Streamlight Strion LED Rechargeable Flashlight Review

Featuring the same great user interface as the Streamlight Stinger, the Strion family of lithium-ion flashlights combines rechargeable performance with the small size of a tactical flashlight. At a mere 6”, about the same size as a 2AA flashlight, the Strion LED puts out a regulated 160 lumens for 2 hours, or up to 7.5 hours on low. Charging is done through a cradle, and the 2.0Ah lithium-ion battery takes up to 3 hours to charge.

Pricing & Ordering

Depending on charger configuration, MSRP for the Strion LED is around $180, and the light is only available in black. Most configurations can be found for around $100.

Like the Stinger series, the Strion LED has package choices for input voltage and number of charging cradles.

In The Box

Included in the box are: Streamlight Strion LED, Li-Ion rechargeable battery, charging cradle, 2 x mounting screws, AC adapter, cigarette lighter adapter, and user manual.

Our package is the 120V AC/DC with 1 holder (item # 74301), and of course, contents depends on the package.


A proprietary rechargeable 2000mAh lithium-ion battery is used in the Strion LED and can be recharged up to 500 times. To compare, this battery has more capacity than the nickel-cadmium battery used in the Stinger series, yet is about half the size and weight.

To charge the light, insert the barrel of the light into the charger, and pull down until it locks. Charging time can take up to three hours.

The Light

The head features a Borofloat high-temperature glass window and partially textured reflector.

The reflector is an interesting feature of the Strion LED. With the textured pattern closest to the LED, this hybrid reflector smoothes out some artifacts in the beam pattern yet maintains good throw.

The light is made of type-II anodized aluminum inside and out. Charging contacts are on the back of the light, on an elevated triangle that orients the light in the charging cradle.

Multiple bands of knurling on the body make it easy to maintain a secure grip on the light.

Tail Cap
On the tail cap is a momentary-capable electronic switch, which is covered by black rubber with Streamlight’s logo on it.

As expected, the switch is responsive with good travel.


The Strion LED shares the same four-mode user interface of the Stinger LED lights.

Single Click: High
A single click activates 100% mode for 185 lumens.

Click and Hold: High-Medium-Low
When either button is pressed and held, the light will slowly cycle through the three brightness levels in high-medium-low-medium-high order. When the button is released, the light will stay in the current mode. The mode can be changed anytime, whether the light is on or off.

Two Fast Clicks: Strobe
With two fast clicks, the 185 lumen strobe is activated. Once again, strobe can be activated anytime, whether the light is on or off. To return the light to high, double-click the switch again (this would turn the light off then immediately turn it back on).

For all modes, a single 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.


The Strion LED is rated for 160 lumens with its Cree XR-E LED, and it has a fairly clean beam pattern due to the hybrid reflector although some rings and artifacts are still visible around the hotspot.

The light is rated for IPX4 water-resistance, which means it can withstand splashing water from all directions, and rainfall would be nothing to be worried about.

When in a quiet environment, we observed a high-pitched inductor whine from the Strion LED for the first couple seconds when it is turned on. Streamlight advised us that this is not an indication of malfunction, and that some people hear it while others do not. If you’re sensitive to high frequencies, do keep this in mind.

Streamlight offers a variety of charging options and add-ons, such as traffic wands and holsters. However, no PiggyBack option is available for the Strion series.


Regrettably, the Streamlight Strion LED came very close to being the first flashlight that we reviewed and didn’t find any drawbacks. For those who find mid-sized rechargeable flashlights to be just a bit too large, the pocket-sized Strion LED is a great choice to have the same performance in a smaller package. Although the Strion LED is not compatible with Stinger family accessories (except for the AC charge cord), it shares the same charger as other Strion series products.

Pros Cons
  • High, medium, low, and strobe modes
  • Direct access to brightness levels and strobe
  • Borofloat glass window
  • High capacity lithium-ion battery
  • Small size
  • Lifetime warranty
  • Possibly audible whine when turning on

    Hello Sir, Madam

    I have streamlight strion with charger and I
    need to know, how do I know when the light is fully charged? Is there an indicator to look for when is
    done charging?

  2. Robin Wang says:


    When the red LED on the charger starts blinking, it is done charging.


  3. Bruce says:

    Hi Robin. Any idea what changed with the Strion in July 2012? Now advertised as High – 250 lumens, up to 2 hours, shines up to 616 ft
    Medium – 80 lumens, up to 4 hours, shines up to 436 ft
    Low – 40 lumens, up to 7.5 hours, shines up to 315 ft

    Still shows the C4 LED, but they sure did something different. It is a great light; no whining noise that I have heard. Lots of them in use where I work; everybody loves it. Thanks for your fantastic web page, by the way!!

  4. Robin Wang says:


    I’m waiting on Streamlight for a response, but I think the LED was upgraded (C4 LED is Streamlight’s marketing term, not an actual type of LED).

    It’s encouraging to hear that they may have fixed the whine, and if the difference is significant enough, we’ll re-review the light.


  5. Stephen says:

    I recently purchased this flashlight about a month ago. After use and the battery wearing down I charged it. The indicator light was blinking so I removed it from the charging holster. Now it won’t turn on. Once and awhile if I click it, the light will blink but it will not stay lit. Can I return it and have them look at it?

  6. Robin Wang says:


    Try removing the battery from the light, then putting it back in and charging it. If that still doesn’t work, contact Streamlight support at 610-631-0600 and I’m sure they will take care of it.


  7. Bruce says:

    Just read your 2012 Strion review!Thanks!I actually ended up getting the new one in October, making it my second LED Strion. Great lights, either version!

  9. John skuta says:

    Hi. I have a sreamlight strion and the adapter for the charger is broken are they available separately? Thanks.

  10. Robin Wang says:


    Try contacting Streamlight, the warranty might cover it. Otherwise, you should be able to order them seperately, part numbers are here:


  11. Ken says:

    I have a streamlight strion and it won’t come on. It has a new tail cap and battery. It light up then goes out.

  12. Larry says:

    I have 4 of the big stream lights
    They are great. I bought the strion and on light
    Number 4 and still not fixed – turns on for 30 -40 sec then goes off wait 15-20 sec then on for
    Fully charged or not does the same thing
    Lil frustrated . Spent a lot on a flashlight and it doesn’t work

  13. Jeremy says:

    I have a Strion and the last few times I’ve used it, it will shut off for no reason. I’ll click the bottom several times and it won’t come back on. If I unscrew the end cap and then screw it back on it will work again. A short time later the same malfunction will occur. Any ideas on what the problem is and how to fix it?

  14. Jhon says:

    It seems to be most of the comments,are the light comes for a few seconds and than does not come on no more I just have that problem it seems to be that needs more time charging I think 3 hours.
