FSMMXAF: Maelstrom MM-X with Burst Mode
Black Finish / Cool White LED

One of our most powerful lights just got brighter. We've upgraded the circuits on our Maelstrom MM-X to give you a massive increase in lumen output.

Thanks to the Burst mode, a new feature for the MM-X, this light will hit a blazing 900 lumens of output for the first 60 seconds on the High setting before ramping down over the next 30 seconds to 50% of the initial output.

The rugged Maelstrom tactical series is designed to perform in the harshest environments. Reliable and versatile, these lights are the result of years of research and input from military and law enforcement personnel. With outputs ranging from 350 to a staggering 15000 lumens, these lights will show the dark who's boss.


The MM-X's seven total modes of output are split into two sets: Regular and Special.
  • Regular: Moonlight-Low-Medium-High
  • Special: Beacon-S.O.S.-Strobe-High
Switching between the modes within a set is very simple - you just tighten or loosen the head to get to your desired mode.The MM-X features a unique 4-point switch engagement in the head of the flashlight that lets you select the different outputs smoothly and silently by simply loosening or tightening the head. Every quarter-turn (approximately 90 degrees) of the head selects a different output. In order of Loosened to Tightened:
  • Off - Auxiliary 2 - Auxiliary 1 - Secondary - Primary
Switching between sets is also simple. Fully tighten the head of the flashlight so that you are in the Primary mode. Then quickly loosen and tighten the head (switching between Secondary and Primary) four times to change to the alternative set of modes.
