*Quantities are extremely limited*

The Maelstrom Regen MMU-X3R is micro-USB rechargeable and reconfigurable. It's also very bright. Maxing at 2000 lumens, it's our brightest light* all while maintaining the compact length of its predecessors.

To charge the MMU-X3R, unscrew the USB cover around the neck of the flashlight. Connect the flashlight to the included USB power supply or any USB socket through the USB cord. After connecting the flashlight, the charging indicator will turn on to indicate that charging is in progress. When the MMU-X3R is fully charged the indicator will turn green. It's as simple as that.

Like the Maelstrom Regen MMR-X, you can choose between five different user interfaces to match your needs for the light. The interfaces range from a simple, one-mode full-power setting, to being able to cycle through all the available modes to find the one you need.

The Maelstrom Regen MMU-X3R ships with one proprietary rechargeable battery already in the packaging. Additional batteries can be ordered here. Do not use any other batteries with this flashlight.

* Yes, we know the XM18 is brighter, but we try not to stroke his ego too much.
