Batteries

A rechargeable 2200mAh lithium-ion battery is used in the M7RX, which uses a battery carrier that is attached to the tailcap.

M7RX_03 M7RX_04

To charge the light, attach the tailcap to the magnetic charger. Charge time can take up to five hours.

The Light

The M7RX is a tactical-sized light with a type-II anodized aluminum body, and the body diameter is slightly larger-than-average because of the battery carrier. The light is easy to grip, especially if you have large hands.

M7RX_07 M7RX_08

Head
The grey bezel distinguishes the M7RX from the M7R, and the head features LED Lenser’s hallmark plastic total internal reflection optic.

M7RX_09 M7RX_10

To adjust the focus of the light, the head can be pushed forwards for a tighter beam or backwards for a wider beam.

Body
Light knurling along the body provides grip for the light.

M7RX_11

Tail Cap
On the tail cap is a momentary-capable elecrtonic clicky switch, which also doubles as charging contacts. The switch is a little firm but has good tactile response and a solid, audible click.

Modes

The LED Lenser M7RX features eight modes, which are divided into three function sets. Modes can be changed with a half press of the switch at any time.

Boost (Momentary)
A half press of the switch activates boost mode for maximum output of 600 lumens.

Power (Normal)
A full click activates power mode, which is approximately 400 lumens.

Dim
Professional and Easy: After turning the light on, hold the switch halfway to activate the adjustable dim mode. The light will continuously fade between low and high, and to select brightness level, release the switch.

Low Power
Professional and Easy: After turning the light on, a half press activates the 85 lumen low mode.

Blink
Professional: After turning the light on, two half presses activates a 3Hz blink.

SOS
Professional: After turning the light on, three half presses activates SOS mode.

Strobe
Professional: After turning the light on, four half presses activates a 20Hz strobe.
Tactical: After turning the light on, a half press activates a 20Hz strobe.

Function Sets

Function sets can be changed with four half presses followed by a full press, and the active function set is indicated by the number of flashes after the mode is changed.

Professional (One Flash)
Professional mode enables all available modes.

Easy (Two Flashes)
Easy mode is designed for simple operation, and only Boost, Power, Low, and Dim are available.

Tactical/Defense (Three Flashes)
Tactical mode is designed for quick activation of strobe, and only Boost, Power, and Strobe are available.

Energy Management Modes

Energy management modes can be changed with eight half presses followed by a full press, and the active energy management mode is indicated by the way the light shuts off after the mode is changed.

Energy Saving Mode (Dimming)
Output is reduced in two steps, from 100% to 35% in the first 10 minutes, then 35% for the next 25 minutes, then 15% for the rest of the runtime. Turning the light off will reset the step-down.

Constant Current Mode (Abruptly)
Output is reduced in one step, from 100% to 40% in the first 10 minutes, then 40% for the rest of the runtime. Turning the light off will reset the step-down.

Performance

Using a Cree XM-L LED, the M7RX has a maximum output of 600 lumens and 13,800 candela. Overall performance is similar to that of the M7R, except brighter and with a cleaner beam pattern.

M7RX_14

In spot mode, the beam pattern has a round hotspot and a square corona. In flood mode, the beam is completely smooth. LED Lenser’s Rapid Focus system allows quick spot to focus adjustment, and simply twist the head to lock/unlock the bezel.

M7RX_15 M7RX_16

Low battery is signaled by a 3Hz blink. The light is rated for IPX4 water-resistance, which means it can withstand splashing water from all directions.

Runtime

M7RX_Runtime

Runtime depends on the Energy Management Mode that is selected, and the different behavior can easily be seen here. In Energy Save mode, the step-down behavior is more aggressive, while Constant Current mode maintains consistent output after the initial step-down.

Accessories

The M7RX comes with several accessories, including a mounting bracket, swiveling belt clip, and lanyard.

Conclusion

In the LED Lenser M7RX, the 600 lumens of output are definitely put to good use. Both the spot and flood beams are excellent and artifact-free on the M7RX, compared to the M7R, which has a couple rings and bands in the beam. However, increased output in the M7RX also brought along an increased MSRP of $300, which makes this light quite costly. Actual retailer pricing is slightly lower, but the LED Lenser M7RX is an excellent multipurpose light that has many features not found in similar lights.

  • Adjustable brightness
  • Focusable Total Internal Reflection optic
  • Magnetic charging system
  • User-programmable function sets

    Hello,
    Do you know is there’s a bigger mIlliampere battery available for this torch?
    It comes with 2200mAh but I’m hoping there’s maybe a 3500 or 5000 mAh
    Battery available.
    Apparently genuine is the only way to go?

    Thank you
    Andrew

  2. Robin Wang says:

    Andrew,

    There is no 5000mAh lithium-ion battery available, regardless of brand.

    With the M7RX, upgrading to a larger capacity battery isn’t going to help, as the light is pre-programmed to step-down after a fixed interval.

    bought this light few days ago in Moscow for 300 $. very nice torch ! instead of trying more powefull batteries i,m very interested in m 17r model of led lenser. Do you think it is worth buying ?

  4. Robin Wang says:

    Michail,

    LED Lenser’s pricing has gone up quite a bit with their latest models, and the M17R is very expensive. For that much money, there are better choices, and I would recommend looking into a rechargeable SureFire.

    Robin, many thanks for your advice ! one more question: making a present to my brother which model is better : m 8 or X 7R ? Thank you

  6. Robin Wang says:

    Michail,

    I didn’t know there was an M8, but rechargeable lights generally have better performance than those that use primary batteries (due to discharge characteristics and voltage maintenance). It’s hard to say which is better, since rechargeable lights are less convenient (non-standard batteries) but cheaper to operate.

    Personally, I prefer rechargeable lights because I don’t need to worry about leaking alkalines or expensive lithiums.

    Hope this helps.

    Robin

    Hi I have just purchased a new charger lead it’s blinking red and Won’t charge can you tell me and help thanks for you advise

  8. Robin Wang says:

    Julie,

    Blinking red means charge error. Make sure the contacts are clean and the light is seated properly. If the issue persists, contact Leatherman support and they will take care of you.
