Pricing & Ordering

MSRP for the R1 Lawman is $455, and the light is only available in black. Several retailers already have the R1 Lawman in stock, and actual pricing is estimated to be around $350.

In The Box

We received our R1 Lawman in pre-production packaging, but production models will come in a cardboard box with similar contents, including: SureFire R1 Lawman, Lithium-Ion rechargeable battery pack, “Dual Fuel” battery carrier with 2 x SF123A batteries installed, AC adapter with international adapters, 12V car charger, rubber anti-roll ring, and user manual.

Batteries

One of the many improvements that the R1 Lawman received during its development was a new, higher-capacity, battery pack. With Panasonic’s Nickel-Oxide New Platform (NNP) technology, the proprietary rechargeable lithium-ion battery pack has an increased capacity of 2900mAh and is rated for 500 full discharge cycles with a 20% loss in capacity (up to 2000 cycles with partial discharge cycles).

To charge the light, connect the AC adapter to the charge port on the light. When the Fuel Gauge LED turns green, the battery is charged to 90% capacity. Typical charge time until 90% is two hours, and it will take an additional two hours to reach 100% capacity. For maximum battery longevity, as mentioned above with the cycle count, you may want to consider only charging the battery to 90%.

While rechargeable systems are cost-effective and convenient, most can only be powered by the rechargeable battery pack, leaving you in the dark if the rechargeable battery is depleted. With “Dual Fuel” capability, the R1 Lawman stands among the few rechargeable flashlights that can also use regular disposable batteries – in this case, 2 x 123A lithium primaries.

If the battery type is changed, or depleted primaries are replaced with new ones, the Fuel Gauge requires a reset by briefly pressing the tail switch.

The Light

Head
Behind the crenelated bezel are an anti-reflective coated glass window and a textured reflector. Flat areas on the head stop the light from rolling away on a smooth surface.

Raised texturing of the SureFire logo on the rubber cover gives tactile feedback for the electronic head switch.

Body
The body is type-III anodized to resist scratches and corrosion, and aggressive knurling along the body of the light provides grip.

Next to the water-resistant charge port is the Fuel Gauge LED, which indicates battery charge status during use and while charging. Green indicates at least 90% charge, orange indicates reduced battery charge, red indicates low battery, and blinking red indicates that it’s time to charge or replace the batteries.

Tail Cap
On the tail cap is a tactical “press for momentary, twist for constant on” switch. To prevent accidental activation in a tactical situation, the tail switch has a raised border and requires more pressure to activate than a regular clicky or electronic switch.

To activate the lockout tailcap feature, unscrew the tail cap until the light no longer turns on (about a half-turn). The light can still be activated by the head switch if the tailcap is locked out.

Modes

Four modes, which are arranged into three function sets, are available for the user to choose from. If multi-mode operation is selected, the head switch will activate the previously used mode.

High
100% mode for 750 lumens. Always accessible from the tail switch, independent of the head switch.

Medium
20% mode for 150 lumens.

Low
2% mode for 15 lumens.

Strobe (Tail Switch Only)
With three consecutive presses or twists, the 750 lumen strobe is activated.

Function Sets

To change the function set, twist the tail cap for constant on and hold the head switch until the light turns off. Unscrew the tail cap, and the R1 is now in the next program set.

Program 1 (Default)
Head Switch: High, Medium, Low, Off
Tail Switch: High Only

Program 2
Head Switch: High, Medium, Low, Off
Tail Switch: High and Strobe

Program 3
Head Switch: High Only
Tail Switch: High Only

When using program 1 or 2, we found a good balance of output and runtime if medium output is programmed in memory for the head switch since maximum output is always accessible from the tail switch should it be needed.

Performance

Using the same high-performance Cree XM-L LED found in the P2X Fury, the R1 Lawman raises the bar once again with its maximum output of 750 lumens, equivalent of a typical 60W incandescent bulb. This combination of a large-die LED with a textured reflector produces a smooth, flawless beam that will light up just about anything.

Due to the electronic head switch and memory feature, the R1 Lawman has a standby drain of 200 µA (or 0.2 mA). Even though this is a fairly significant standby drain compared to other lights, it will take 1.6 years to drain the 2900mAh battery, so we don’t expect it to be an issue. For long-term storage, it is recommended to remove the battery pack.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

SureFire uses tactical and total runtime, which are not necessarily consistent with ANSI FL-1 Standard specifications. For the R1, maximum output runtime is given as tactical runtime (50 lumens = 7%), and lower output runtimes are given as total runtime until battery exhaustion.

When using the rechargeable battery, the R1 reduces output to 500 lumens after a 2-minute burst of 750 lumens. Due to non-linear brightness perception, the reduction during actual use is not as noticeable as the numbers seem to imply.

Accessories

Almost everything that you may need is included with the R1, including a variety of charging and battery options. One unexpected item was the anti-roll ring, which gives the R1 even more stopping power when set down on a smooth surface.

Conclusion

Whether the intended use for your flashlight is tactical or not, the SureFire R1 Lawman is guaranteed to perform in any situation where an illumination tool is indispensable. SureFire has taken a while to get the R1 Lawman just right, having gone from the original 300-lumen prototype announced at the 2011 SHOT Show, to the 700-lumen model with a one-hour runtime shown at the 2012 SHOT Show, and finally settling on a 750-lumen model with a 1.75 hour runtime for production. By combining multi-mode operation with memory and a medium output of 150 lumens, the R1 Lawman is not just extremely bright, but also convenient and practical for many uses where runtime may be preferred over output.

One aspect about the R1 Lawman is still lingering, and you might have guessed it already – price. It shouldn’t surprise those who are familiar with SureFire products, but the price is indeed quite steep compared to other rechargeable lights. That being said, the R1 Lawman has introduced a new standard for rechargeable flashlights, leaving current models comparable only to the R1’s medium mode, so there’s definitely a cost associated with all of this new technology. There’s no doubt about the R1 Lawman when it comes to features and performance, but we can’t say the same about the pricing as we did with the P2X Fury. While the SureFire R1 Lawman could be the best rechargeable flashlight that money can buy, we’ll have to leave it up to your budget or equipment allowance.

• Runtime: 3h
• Battery: 2 x AAA
• Length: 5.0″
• Diameter: 0.7″ body
• Weight with Batteries:2.2 oz.
• Warranty: Limited Lifetime
• MSRP: $29.99

Pricing & Ordering

MSRP for the 5.11 ATAC PLx flashlight is $29.99. This flashlight is only available in black.

In The Box

Included in the ATAC PLx’s box are: 5.11 Tactical ATAC PLx flashlight, 2 x AAA alkaline batteries, and a user manual.

Batteries

It operates on two AAA batteries, which are to be inserted in the conventional way of positive end first.

The Light

Head/Body
The head and body, which are integrated and cannot be separated, is type-II anodized aluminum and houses a polycarbonate window and a smooth reflector.

Four lines of jagged protrusions around the body and simple patterns, as well as the pocket clip, provides grip on the body, and the forward-facing pocket clip can be removed if desired.

Tail Cap
On the tail cap is a forward clicky switch, covered with black rubber. The rubber protrudes, so the light cannot tail-stand.

Operational Modes

Like many other compact flashlights, the ATAC PLx only comes with single mode.

Performance

The 5.11 ATAC PLx flashlight uses the Cree XP-C LED, which produces 69 lumens from two AAA batteries. Since this is a general purpose light, the hotspot isn’t tightly focused for far distances but it does the job well for close proximity. The beam is both smooth and clean.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

Conclusion

LED technology is rapidly improving and the 5.11 Tactical ATAC PLx flashlight is one of the brightest penlights on the market right now, yet is still small enough to fit comfortably in a shirt pocket. Although the compact AAA power source limits potential performance, we’ve found the PLx to be bright enough for many everyday tasks. This probably won’t be a good choice for patrolling your property, but with its compact size, you are more likely to have the PLx with you when you need it. All in all, we were satisfied with the quality and output of the 5.11 ATAC PLx flashlight.

Pricing & Ordering

MSRP for the SureFire P2X Fury is $155, and the light is only available in black.

In The Box

Included in the blister packaging are: SureFire P2X Fury, 2 x 123A lithium batteries (installed), user manual, battery safety notice, registration card, and a SureFire sticker.

Batteries

Like most of SureFire’s lights, the P2X Fury uses lithium 123A batteries. These batteries have twice the voltage of a common 1.5V AA battery, and this high energy density makes them ideal for high-powered flashlights.

High energy density also makes it essential to only use quality 123A batteries, as low-quality or counterfeit 123A batteries can be dangerous. SureFire recommends only using Duracell, Energizer, Panasonic, or SureFire branded CR123’s. Rechargeable 3.2V lithium phosphate 123A batteries can also be used.

The Light

Head
The head features an anti-reflective coated glass window and a textured reflector. Flat areas on the head stop the light from rolling away when set on a flat surface.

Body
The body is type-III anodized, which is a tough finish that resists scratches and corrosion. Instead of knurling, the Fury has a sculpted body which is smooth and easy to grip.

Tail Cap
On the tail cap is a forward click switch, which is covered with textured rubber. To activate the lockout tailcap feature, unscrew the tailcap until the light no longer turns on (usually about a quarter-turn).

Modes

Based on the 6PX Pro, the P2X Fury is also a dual-output flashlight designed for non-tactical use.

Low
With the first press or click, the 15 lumen low mode is activated.

High
After returning to off, a second press or click activates the maximum output of 500 lumens.

Performance

With the combination of high-energy 123A batteries and a high-performance Cree XM-L LED, the Fury is capable of a maximum output of 500 lumens. This is equivalent to a 40W incandescent light bulb, which is an incredible amount of light from a compact flashlight. A textured reflector produces a smooth and floody beam pattern that easily lights up a wide area.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

SureFire states runtime for their lights as “tactical runtime,” which is runtime until 50 lumens. For the Fury, the tactical runtime coincides with the ANSI FL1 Standard because 10% initial output is 50 lumens. Runtime is significantly shorter with rechargeable lithium phosphate 123A batteries, so we would recommend carrying a spare set of primary 123A’s if you will be without access to a charger.

Accessories

SureFire offers several accessories for the Fury, including spare battery carriers, filters and diffusers, and lanyards. More interesting, however, is the rechargeable 123A battery kit that we received to test with the Fury.

Manufactured by K2 Energy, the 3.2V lithium phosphate 123A batteries have a capacity of 600mAh. Compared to 3.0V lithium primary 123A batteries, which are approximately 1500mAh, the rechargeable lithium phosphate batteries last about half as long. That being said, the rechargeable kit not only pays for itself after just a couple charge cycles, but they are also safer to use than lithium primaries.

Pricing for the kit, which includes two batteries and a charger, is expected to be $29, and additional pairs of batteries can be purchased for $12. Both the kit and extra batteries will only be sold on the SureFire website and should be available for order within a couple weeks.

Conclusion

There’s no doubt in our minds that the SureFire P2X Fury is bright – 500 lumens is a serious amount of output. Even more impressive than its output is the moderately priced MSRP of $155, with many retailers selling the Fury for even less. If you’ve been using tactical lights for a while, you are probably already familiar with using 123A batteries. However, for those who are new to the battery type, the SureFire rechargeable lithium phosphate kit makes it easy to overcome the expense of lithium 123A batteries and still get great performance from the Fury.

Our only gripe with the P2X Fury is that the low mode activates first, and after getting accustomed to the 500 lumen high mode, the low mode really doesn’t seem very bright. Even though the P2X Fury isn’t designed for tactical use, we would have preferred a little more light on the low mode because it’s quite a big jump from 15 lumens on low to 500 lumens on high. When we mentioned this to SureFire, we learned that the P2X Fury is actually just the first model in the Fury family of lights, with Tactical, Defender, and CombatLight versions due to release in several months.

If the dual-output of the P2X Fury is not the thing for you, the upcoming tactical versions will feature one-step access to high. It’s always good to have choices, right?

Pricing & Ordering

MSRP for the Mini Maglite Pro is $29.99, with the Pro+ priced slightly higher around $32.99. Black is only available at the moment, but both models will be available in black, grey, blue, red, silver, or UCP camo.

In The Box

Included in the blister packaging are: Mini Maglite Pro/Pro+ LED Flashlight, 2 x AA Duracell alkaline batteries, and holster.

Batteries

Like the original Mini Maglite LED, both the Pro and Pro+ operate on two AA batteries. ANSI FL1 specifications for the lights are for alkaline batteries, but NiMH rechargeable and lithium primaries can also be used.

The Light

Head
The head features a plastic window and a deep smooth reflector. Optimal focus can be achieved with a quarter turn of the head, or the head can be removed for “candle mode.”

A glass window may be installed using Mag Instrument part #108-617.

Body
The entire light is type-II anodized aluminum inside and out, which prevents corrosion and also electrically insulates the light.

Knurling along the body of the lights ensures a solid grip but do not prevent the light from rolling when set on its side.

Tail Cap
Since these are twist-operated lights, there’s only a lanyard hole on the tail cap.

Modes

Multi-mode operation differentiates the Mini Maglite Pro+, which uses an accelerometer for selecting the power-saving low mode, from the single output Mini Maglite Pro.

Full Power (Pro+)
100% brightness at 245 lumens.

Power Save (Pro+)
Simply point the light straight down before turning it on for 25% brightness, or 61 lumens.

Performance

Using the same Cree XP-G LED as the XL200 and ML125, the Mini Maglite Pro and Pro+ are rated for 226 and 245 lumens, respectively. Not only is this an incredible amount of output compared to the current 77-lumen Mini Maglite LED, but the Pro and Pro+ holds ground even when compared to tactical CR123 or rechargeable lights.

At the point when the light turns on, the beam pattern tends toward that of a floody work light, which is ideal for work in a Pro-fessional environment (pardon the pun) where light is often needed at close range. With another quarter turn of the head, the beam reaches optimal spot focus.

Since the LED module is disconnected when the head is fully tightened, we’re pleased to report that there’s no parasitic standby drain to be found on either light.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

As efficient as LEDs are, heat is still produced and has to be dissipated, so step-down regulation is used to prolong battery life and reduce heat. This behavior does not give accurate comparisons for one runtime cycle, so we conducted an extended runtime test where we power cycled the lights to reset the timer.

If the lights are operated with a 90% duty cycle (13.5 minutes on, 1.5 minutes off), maximum output is maintained for a shorter amount of time and the runtime graph resembles that of a flashlight without an automatic energy-saving step down.

Accessories

Maglite includes a basic open-top holster with blister pack versions of the Mini Maglite, and the Pro/Pro+ are no exception.

An optional closed-top, open-bottom holster is available as an OEM accessory (useful if you plan to attach a lanyard to the light, since it may not fit in the included holster), and most Mini Maglite accessories such as anti-roll rings and glass windows are compatible.

Conclusion

Maglite has been continuously updating their product line over the past couple years, not only bringing performance and functionality to new levels, but also value. It’s no exception with the Mini Maglite Pro, which offers an unprecedented 200+ lumens for under $30. Priced only slightly higher than the Pro, the Mini Maglite Pro+ includes an accelerometer for intuitive mode-switching.

One thing that we would really like to see is an OEM tail cap switch upgrade, since the twist operation does require re-focusing the light each time it’s turned on. To put things into perspective, the low mode of the Mini Maglite Pro+ is about the same brightness as the high mode of the Mini Maglite LED. Even though these lights have impressive peak performance, they are also designed to be economical for everyday use.

Pricing & Ordering

MSRP for the ML100 is $54.99 to $58.99, and the light is only available in black (contrary to the flyers we posted in 2011).

In The Box

Included in the blister packaging are: Maglite ML100 LED Flashlight, 2 x C-cell alkaline batteries (or 3 x C-cell for the 3-cell model), and user manual.

Batteries

The ML100 operates on C-cell batteries, which makes the light less bulky and easier to grip than wider D-cell lights. However, the C-cell form factor is not very popular, so alternatives such as battery adapters for AA’s are available (which we used for our NiMH runtime test). Using these adapters not only creates commonality with AA batteries, but also further reduces weight.

The Light

Head
The head features a plastic window and a shallow smooth reflector. Unlike previous models, focusing is continuous action, so the head cannot be removed.

Body
Knurling along the flashlight body gives the ML100 better grip, and the light is type-II anodized aluminum inside and out.

The head mounted switch is an electronic switch similar to that of the XL-series lights.

Tail Cap
A band of knurling is found on the tail cap, and that’s about it for the exterior.

Threads are anodized, allowing lock-out with a quarter turn of the tailcap.

Modes

Five modes, which are arranged into four function sets, are available for the user to choose from.

Full Power
100% brightness at 137 lumens.

Power Save
25% brightness at 34 lumens.

Strobe
The 12Hz strobe feature is designed for disorienting or getting somebody’s attention.

SOS
SOS is the International Morse Code Distress Signal, which is three short flashes, three long flashes, and three short flashes.

Momentary
If momentary is enabled, the switch must be pressed twice for Full Power. While this is not true momentary operation since Full Power cannot be activated from momentary, it’s a clever workaround of the electronic switch.

Function Sets

To change the function set, start with the tailcap slightly unscrewed so that the light does not turn on when the switch is pressed. Press and hold the switch while screwing on the tailcap, and once the tailcap is screwed on all the way, the light will start flashing. The number of flashes corresponds to a function set’s number, which are cycled. Releasing the switch selects the function set.

Function Set 1 (Default)
Full Power, Power Save, Strobe.

Function Set 2
Full Power, Power Save, SOS.

Function Set 3
Momentary, Full Power, Power Save.

Function Set 4
Momentary, Full Power, Strobe.

Performance

One of the upgrades that the ML100 received during its redesign was the more efficient Cree XP-E LED, increasing light output to 137 lumens. Since the XP-E LED has a smaller chip size than the XP-G used in the ML125, the ML100 has a more intense beam that will travel a longer distance.

The redesigned focusing assembly of the ML-series allows fine-tuning of the ML100’s beam pattern, if desired. Lights are aligned at the factory and both of our ML100’s had well-focused beams, so we didn’t find this necessary. Although focusing is smoother, there are still some rings and holes when the ML100 is unfocused.

We measured standby power drain of 47.2 µA (or 0.0472 mA) on the 2-cell ML100, and 59.8 µA (or 0.0598 mA) on the 3-cell ML100. Since C-cell batteries have more capacity than the AAA’s used in the XL-series, this is less of a concern, but we would recommend locking out the tail cap if the light will not be used for an extended period of time.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

Power-save regulation is also used on the ML100, which reduces output to approximately 50% after 12 minutes of runtime.

If the ML100 is operated with a 90% duty cycle (13.5 minutes on, 1.5 minutes off), maximum output is maintained for a shorter amount of time and the runtime graph resembles that of a flashlight without an automatic energy-saving step down.

Accessories

Maglite C-cell mounting brackets and belt rings are compatible with the ML100, but since many mid-sized rechargeable flashlights have similar body diameters, open-bottom holsters (such as the Pelican 7078 below) designed for those lights can also be used.

Conclusion

Not only is the ML100 an improved LED flashlight, but also a major step in the right direction for Maglite. Previous generations of Maglite’s MAG-LED technology, including the original LED drop-in replacements and even the current LED D-cell lights, had problems with heat dissipation and irregular beam patterns because they were originally designed for incandescent bulbs. However, neither is a concern anymore with the new ML-series, and the Maglite ML100 offers a lot of features and performance for the $50 price point.

Pricing & Ordering

Depending on charger configuration, MSRP for the Knucklehead is between $120 and $350, and the light is only available in black. Alkaline models can be found for around $80, and rechargeable configurations range from $140 to $180.

In The Box

Included in the box for a rechargeable model (item # 90607) are: Streamlight Knucklehead, NiCd rechargeable battery, alkaline battery cartridge, charging stand, 4 x mounting screws, AC adapter, cigarette lighter adapter, magnet, magnet screw, hex wrench, and user manual.

For an alkaline model, the following would be included: Streamlight Knucklehead, alkaline battery cartridge, magnet, magnet screw, hex wrench, and user manual.

Batteries

Proprietary nickel-cadmium batteries (rechargeable up to 1000 times), or 4 x AA batteries, can be used in the Knucklehead. Battery flexibility is a great plus for the Knucklehead, as the Knucklehead works well on both alkaline and NiMH rechargeable AA batteries such as the Sanyo Eneloop.

To charge the light, insert the base of the light into the charger, and push down until it locks.

Streamlight advises that the “memory effect” common to NiCd batteries is rare under normal flashlight use, so it isn’t recommended to condition the battery with frequent complete discharging.

The Light

Head
The head consists of a heavy duty rubber bezel, anti-scratch coated polycarbonate plastic window, and a textured reflector. The scratch resistance comes from a silicon dioxide coating that is cured onto the plastic for a minimum pencil hardness of 3H (meaning that only a pencil with 3H hardness or higher will be able to scratch the window).

Metal contacts between the head to the body allow continuous 360° swiveling and is sealed with an O-ring.

Body
The light is made of lightweight nylon polymer, and the electronic switch is designed to be easy to press even with thick gloves and sonic welded for durability.

On the back of the light are two attachment accessories – removable magnet with 135 lb. pull strength and a retractable hook.

Base
On the base is the battery cover with charging contacts.

Alkaline batteries are not connected to the charging contacts, so there is no risk of accidentally charging the alkaline battery pack.

Modes

Four modes are available through a simple user interface, and pressing and holding the switch cycles through each of the modes.

Mode #1: High
A short click activates 100% mode for 200 lumens.

Mode #2: Low
When the switch is pressed for one second, the 63 lumen low mode is activated.

Mode #3: Flash
When the switch is pressed for another second, the 200 lumen flash is activated.

Mode #4: Moonlight
If the switch is pressed for another five seconds, the approximately 1 lumen moonlight mode is activated.

For all modes, a short click will turn the light off. Since the light uses electronic switches, there is a small standby current drain of 5 µA (0.005 mA), which is negligible.

Performance

The Knucklehead is rated for 200 lumens with two Luxeon Rebel ES LEDs, which produce a smooth flood beam. Due to the shape of the reflector, the beam is actually square.

The light is rated for IPX4 water-resistance, which means it can withstand splashing water from all directions, and also has safety approvals for use in hazardous environments (see Fact Sheet link at the bottom for details).

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

Accessories

Streamlight offers a variety of charging options, such as the PiggyBack charger, which charges both the light and a spare battery at the same time. It is available with a choice of standard or fast charging for the primary charger, but only steady charge for the spare battery.

Conclusion

It’s a busy time for IT as we near the end of the year, so it has taken us longer than usual to publish this review. On the other hand, we’ve been able to use the Knucklehead in a variety of practical situations, and it’s quickly becoming our preferred light for work. Dual-LEDs in the Knucklehead provide an even flood beam for area illumination, unlike the focused beam of a flashlight that can be blinding, especially if shined on a white or metallic surface. With the Knucklehead’s swiveling head, it’s easy to direct light where it’s needed.

One thing to keep in mind is that rechargeable Knucklehead packages cost about twice as much as the alkaline model – a significant premium. Performance with rechargeable NiMH AA batteries is similar to the rechargeable model; however, having removing the batteries for charging can be time-consuming compared to variety of charging options available for the rechargeable version. Unless you require the convenience of a rechargeable system, our verdict is that the alkaline version of the Knucklehead will offer the most utility, and value.

When changing batteries, care must be taken because the pocket clip is attached to, and turns with, the tail cap.

The Light

Head
The head, which cannot be removed from the body, features a polycarbonate window and a smooth reflector.

Body
The light is type-II anodized aluminum inside and out. Grip is provided by the pocket clip, which also prevents the light from rolling.

Tail Cap
On the tail cap is a removable two-way pocket clip and a forward clicky switch covered with black rubber.

Due to customer issues with the switch cover wearing out, Streamlight has made the switch cover thicker and also user-replaceable (spare cover is included). Clicking the switch takes more force than the older, non-C4 version MicroStream.

Performance

The MicroStream is rated for 28 lumens, and uses the Cree XP-C LED. As expected for a light with this LED, the hotspot isn’t tightly focused or well defined like a tactical light, but overall the beam is smooth and clean.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

The ANSI FL-1 standardized output and runtime specifications were made using alkaline batteries, which are included with the lights, and NiMH rechargeable and Energizer Lithium primary AA’s may also be used for increased brightness and more consistent output. The MicroStream has a long, useful runtime that, in our test, exceeded ANSI specifications by over an hour.

Conclusion

We’ve said this before, but we’ll say it again: the best flashlight is not going to be the brightest one you have at home, but the one that you carry everywhere with you. We’re not particularly fond of small twist-operated lights as they can be difficult to turn on, so the tail switch is a big plus for the MicroStream.

With the $20 price point and the holidays just around the corner, the Streamlight MicroStream will be a great gift for that outdoor enthusiast or gadget lover in your family!

Pricing & Ordering

MSRP for the 5.11 ATAC A1 is $54.99, and the ATAC A2 is $64.99. Both lights only come in black.

In The Box

Included in the box are: ATAC A1 (or A2) flashlight, 1 x AA (or 2 x AA) alkaline battery, a Break-Away Lanyard, and user manual.

Batteries

One of the first 5.11 flashlights to use alkaline batteries, the ATAC A1 and A2 lights operate on one and two AA batteries, respectively.

The Light

Head
The head, which cannot be removed from the body, features a plastic window and a textured orange-peel reflector.

Body
The light is type-II anodized aluminum inside and out, and the forward-facing pocket clip can be removed if desired.

Some ribbing and patterns, as well as the pocket clip, provides grip on the body. Ribbing is also present on the inside to reduce battery rattle.

Tail Cap
On the tail cap is a forward click switch, covered with black rubber. The rubber protrudes, so the light cannot tail-stand.

Operational Modes

Like many other tactical flash, the 5.11 ATAC A1 and A2 flashlight has 3 modes.

High
A full click (or a partial press) will run the light at the maximum output of 162 lumens.

Ultra Low
A single tap and a full click (or a partial press) will activate ultra low power mode at 15 lumens.

Strobe
Double tap and a full click (or a partial press) will activate the strobe mode at maximum output.

Performance

The 5.11 ATAC A1 and A2 are ANSI rated at 103 and 162 lumens, respectively, and both use the Cree XP-E LED. The lights have smooth spill from edge to hotspot.

Although the hotspot is focused, the beam is more floody and better suited for closer work where a strong spot beam can be too reflecting. Overall, the beam is clean and smooth, thanks to its textured orange-peel reflector.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

The light output drops to 50% within 2 hours and remains constant for about 5 hours before shutting off. 5.11 designed the circuit to go into an energy saving mode in order to extend the run-time. At the request of Law Enforcement professionals for a longer lasting battery life in the field, the light was designed to automatically reduce the current output gradually after exceeding the 10-15 minute threshold time.

However, this gradual reduction of energy is less pronounced to the eye because of a non-linear perception of “brightness” (click here for more information).

Accessories

Both lights come with a break-away lanyard that is designed for quick detachment when necessary (for example, if the flashlight gets caught on machinery or somebody tries to grab it). On top of that, there is a rubber ring around its tail cap designed to prevent the flashlight from rolling over.

Conclusion

5.11’s ATAC A1 and A2 flashlights are suitable for everyday carry use with strong construction, compatibility with common batteries, and multiple modes for any kind of usage. At 162 lumens, the ATAC A2 would put it at one of the brightest AA flashlights we have ever tested.

Although the lights are a bit pricey compared to other AA competitors, the ATAC A1 and A2 are well built and backed by 5.11’s lifetime warranty. Our only concern with the lights would be the durability of the angled bends on the pocket clip, but all in all, we are pleased by the quality and output of these flashlights.

ANSI/NEMA FL 1-2009 Standard

Commonly abbreviated as the FL1 Standard, the ANSI/NEMA FL 1-2009 Standard is a set of flashlight performance guidelines. Before the introduction of these standards, you may have seen variety of phrases on flashlight packaging, such as these:

• “3W LED” was a common term used when high performance LEDs, such as the Luxeon, were first introduced. LEDs have varying efficiencies and rarely operate at the rated power, so this doesn’t really have any meaning.
• “1 million candlepower” (or any other multiple of a million), is often seen on lanterns and spotlights. A million of anything is impressive, but how bright is one million candles?
• “High-flux LED” is really just a fancy way to say that the LED is bright, but unless you’re an engineer, it’s only going to make you scratch your head.

With the FL1 Standard, ambiguous marketing phrases are a thing of the past, and direct comparisons can be made between flashlights from different manufacturers. Adherence to the FL1 Standard is voluntary, although the vast majority of manufacturers have adopted the standard. Here’s how the ratings are defined:

Light Output [Lumen]
Light output is a measurement of luminous flux using an integrating sphere. The unit of luminous flux, lumen, is a measurement of energy.

Peak Beam Intensity [Candela]
Peak beam intensity is a measurement of luminous intensity at the middle of the flashlight beam. The unit of luminous intensity, candela, is a measurement of energy.

Beam Distance [Meter]
Beam distance is defined as the distance from the flashlight where illuminance is equivalent to a full moon on a clear night.

Runtime [Hours]
Runtime is defined as the amount of time, rounded to the nearest quarter hour, until output drops below 10%.

Water Resistance [IPX Rating]
Water resistance is stated using the IP rating system, and three ratings are used.

• IPX4 – water-resistant, or water splashed from all directions
• IPX7 – water-proof, or temporary submersion at 1 meter for 30 minutes
• IPX8 – submersible, or continuous submersion at some specified depth for 4 hours

Impact Resistance [Meter]
Impact resistance is tested with drops onto a concrete surface at the specified height with all intended accessories, including batteries, installed.

Interpreting the FL1 Standard

Now that we have defined these ratings, let’s see what the not-so-obvious ratings mean.

Light Output vs. Peak Beam Intensity
Although higher output seems like it should correspond to higher intensity, a light with more lumens is not necessarily “brighter.” Here’s why:

• Light output is determined by the total amount of light coming out-the-front (OTF) of the flashlight, which is related to the LED’s efficiency and how much power it uses.
• Peak beam intensity represents brightness as perceived by the human eye, which is related to how the beam is focused by the optical system (typically a reflector, lens, or optic).

So, which is more important? Light output can be thought of as “raw material,” but it’s how that light is dispersed that determines usefulness. For example, a fluorescent lamp has high output but low intensity (a dispersed, or flood, beam), whereas a laser and has low output but high intensity (a focused, or spot, beam).

Both are useful for their intended purposes, but neither would make a good flashlight. Thus, the candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot- or flood-type beam.

• Spot beams (large cd/lm ratio) are great for lighting up distant objects, but at close range, the hotspot may be blindingly bright.
• Flood beams (small cd/lm ratio) are great for close work, but for distant objects, there’s not going to be much light.

As a reference, well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

Peak Beam Intensity vs. Perceived Brightness

Brightness, as we think of it in everyday terms, is actually a difficult measurement to grasp numerically. While 10,000cd will appear brighter than 5,000cd, it will not appear twice as bright. The reason is because our perception of brightness is non-linear, meaning that “twice the intensity” will not appear “twice as bright.”

Keeping this non-linear relationship in mind is important for making Peak Beam Intensity comparisons, and a rough estimate is that for a light to appear twice as bright to the eye, four times the intensity is required.

Beam Distance
Beam distance is calculated from peak beam intensity, so there is actually no new information here. In addition, a full moon on a clear night is not really a useful amount of light, so don’t put too much weight on this specification.

Limitations of the FL1 Standard

While the FL1 Standard is a big step forward, no standard is free of issues, and there are some limitations to the FL1 Standard. Knowing the limitations of a standard is just as important as knowing what the standard means, and the biggest limitation of the FL1 Standard is the runtime rating.

Runtime
Here’s a trick question: when is a 1.5V battery actually 1.5 volts? Ideally, always, but an alkaline battery’s voltage decreases as it discharges, so it would almost never be 1.5 volts. This is why LED flashlights require complex electronics, but not all flashlights behave the same way. To capture this behavior, runtime must be presented as a graph, which is not required by the FL1 Standard. Take this sample data from our runtime tests:

This runtime chart tells us the following information:

• Flashlight 2 has the shortest runtime, but it is consistent and within 10% of the initial brightness.
• Flashlight 1 has slightly longer runtime than Flashlight 2, but brightness (which is mostly less than 50%) is continuously decreasing.
• Flashlight 3 has a long runtime that is maintained at 50% brightness.

Based on the runtime graph, we can say that flashlight 2 is a better choice than flashlight 1, and flashlight 3 is the good choice for extended runtime (in fact, flashlight 1 and 2 are actually the same flashlight using different batteries, but that’s the topic for another article).

These observations would not be possible with just a runtime rating, which is why conduct our own independent ANSI FL1-compliant testing and include runtime graphs in our reviews to supplement the FL1 Standard Runtime. For more information about our runtime tests, please click here.

Impact Resistance
While LEDs are reliable solid-state devices with no moving parts, electronic circuitry that regulates power to the LED tend not to be as durable. Occasional drops shouldn’t be an issue, but repeated stress can cause damage that may lead to erratic operation or failure. Our advice would be to treat LED flashlights like any other electronic device and avoid drops or other damage if possible.

Pricing & Ordering

MSRP for the Pelican 1910 is $32.95, and $35.95 for the 1920. Both lights are only available in black.

In The Box

Included in the 1910’s box are: Pelican 1910, 1 x AAA alkaline battery, and user manual. Included in the 1920’s box are: Pelican 1920, 2 x AAA alkaline batteries, and user manual.

Batteries

Both lights operate on AAA batteries, and contrary to initial product images, batteries are to be inserted positive end first, not the other way around.

The Light

Head
The head, which cannot be removed from the body, features a polycarbonate window and a smooth reflector.

Body
The light is type-II anodized aluminum inside and out, and the forward-facing pocket clip can be removed if desired. Some ribbing and patterns, as well as the pocket clip, provides grip on the body.

Tail Cap
On the tail cap is a forward clicky switch, covered with black rubber. The rubber protrudes, so the light cannot tail-stand.

Modes

As with the 7060 and most of Pelican’s lights, the 1910 and 1920 are single mode, so that’s about it for this section.

Performance

The Pelican 1910 is rated for 39 lumens, the 1920 for 67 lumens, and both lights use the Cree XP-C LED. Since these are general purpose lights, the hotspot isn’t tightly focused or well defined like a tactical light, but overall the beam is smooth and clean.

Runtime

If you haven’t read our article about runtime graphs and the ANSI FL1 Standard, please click here.

The ANSI FL-1 standardized output and runtime specifications of these lights were made using alkaline batteries, which are included with the lights, and NiMH rechargeable and Energizer Lithium primary AA’s may also be used for increased brightness and more consistent output.

Conclusion

As LED technology improves, lights are not only getting brighter, but also smaller. While the Pelican 1910 is a little too large to be a keychain light, its rated output of 39 lumens makes it one of the brightest single AAA lights. The 1920 is also one of the brightest 2AAA “penlights” with its 67 lumen output. These lights are priced about $10 more than similar offerings, but if you need a brighter pocket light, it’s definitely worth it. Overall, we were impressed with the build quality and output of the Pelican 1910 and 1920 flashlights.
