LED Quality

Olight M2R pro crenated bezel LED

The Olight M2R Pro features the Cree XHP35 HI TIR lens for uniform light with a hot corona.

The XHP35 is often used in high power flashlights. With this LED many flashlight manufacturers got more output at same size and battery configuration.

The light beam is capable for a long distance throw with its powerful 22400 candela rating, which can be used as a spotlight that is capable of reaching ~200-300 meters, and also be able to punch through any photonic barriers such as fog, rain and other ambient lights.

Strobe Mode

The strobe feature can be activated via pressing the thumb button or the tail cap. The user can program the strobe activation method based on preference very easily.

The strobe mode is a must have feature as a signaling device for outdoor survival, draw immediate attention and as close up personal defense blinding tool.

When the strobe light is activated, it operates at the highest 1800 lumens intensity.

Tail Cap & Thumb Button Activation

The Olight M2R Pro has two button activation feature, and both has its own practical use for different applications, and the tail cap switch can be programmed to fit your needs.

Both buttons have very positive controls and feedback with or without gloves.

The tail cap button design has been upgraded from the original M2R with extruded protectors around to prevent accidental button press, and the height of the button is also raised for better tactile activation control.

For personal defense use, it's recommended to program the tactical tail cap to activate the max lumen strobe by press & hold the button all the way down, then release to turn the strobe off.

For steady momentary on light, the user just need to press the tail cap half way to activate, which is highly recommended to leave light in this mode to give the user super tactile & responsive button operation.

The thumb activation button is an EDC feature that allows for constant-on and to cycle through different lumen intensities by double tapping the button.

Magnetic Base

The magnetic base of the M2R Pro allows the user to stick the light to any magnetic surfaces for providing hands free steady light mount. This is very helpful for car mechanics and anyone who need low light illumination without holding the light.

The magnetic base also allows for the USB Magnetic Charging Calbe (MCC) to be attached.

The body of the M2R Pro features good/simple knurling textures in the mid section of the body to give the user a very positive grip without slipping when activating the light via tactical grip.

The anti rotation geometry is also built in on the upper portion of the grip so you don't have to worry about the light rolling away when you're working on cars or other tasks where you had to free up your hands.

Rechargeable Battery

olight 3.6v 5000 mah battery
Olight USB MCC cable

The Olight M2R Pro features an rechargeable 3.6V 21700 battery with 5000 mAh capacity. Under normal mid-lumen intensity use, the light will last you 10+ hours if you use it for hiking in the dark, or working on cards.

On turbo mode, the battery drains the fastest with about 5 mins of constant on.

The user can monitor the battery status by checking the power indicator

To charge the battery, the package comes with Olight's 3rd generation magnetic MCC fast charging USB cable.

What we like is that you save tons of money buying batteries, and you can recharge it on the go if you have a portable battery bank.
