SureFire M3LT CombatLight

13 Jul

SureFire has announced what it claims to be the brightest LED flashlight ever, the M3LT CombatLight, delivering a max of 400 lumens. (although the Fenix TK-30 and TK-40 models are LED powered and claim to deliver 630 and 650 lumens respectively?). In any case, 400 lumens is plenty bright for most uses.

Here is a little info on the M3LT from SureFire’s web site:

Max Output 400 .0 lumens
Low Output / Runtime 70 .0 lumens / 8.5 hours
Tactical Runtime* 1 .7 hours
Length 8 .7 inches
Bezel Diameter 2 .5 inches
Weight w/Batteries 10 .9 ounces
Batteries 3 123A (included)

A large-diameter Turbohead, a Total Internal Reflection (TIR) lens, and an ultra high-output 4-die LED emitter come together to produce a powerful, focused beam suitable for spotlight/searchlight applications—yet the light is less than 9 inches long. The high-performance LED is virtually immune to failure since there is no filament to burn out or break, and it provides a far longer runtime per set of batteries when compared to incandescent lights of similar lumen output. They come standard with a tough aerospace aluminum body with a Mil-Spec hard-anodized finish for extreme durability. These 4-die LED illumination tools also feature an ergonomic CombatGrip configuration, suited for flashlight/handgun techniques and provide a secure hold with cold, wet, or gloved hands. All models feature tactical switching— a pushbutton switch that (1) is located on the tailcap for fast no-look access and for use with flashlight/handgun techniques, and (2) always activates maximum light output when fully depressed.


  • Virtually indestructible 4-die LED emitter regulated to maximize output and runtime
  • Two output levels—high for maximum light, low for extended runtime
  • Turbohead TIR lens produces tight, extended-reach beam
  • Coated, tempered window resists impact and thermal shock, maximizes light transmission
  • CombatGrip for secure hold in all conditions
  • High-strength aerospace aluminum body, Mil-Spec hard-anodized for extreme durability
  • Two-stage tactical tailcap switch—press for momentary-on low, press further for high, twist for constant-on at either level
  • Weatherproof—O-ring and gasket sealed
  • Includes high-energy 123A batteries with 10-year shelf life

SureFire has a great reputation among it’s users for producing high quality, dependable lights. The M3LT is priced in what I consider the ‘serious flashlight enthusiast’ category at an MSRP of $450.00.
