SureFire G2X Pro Dual-Output LED Flashlight review

This is my second Surefire flashlight. I've owned several other decent LED lights (Olight, Fenix, etc), and this is by far my favorite brand. It's simple, and it works. My only gripe is that I am unable to use the rechargeable 18650 batteries like in other lights. The body of the light is not shaped wide enough to fit the slightly wider batteries. But, I have a decent supply of cr123a so that helps.

This SureFire G2X Pro Dual-Output LED Flashlight review based on real experience in using it .

Our field team has several of them now and we understand why they cost a bit more: not only are they American-made, they're insanely bright (like... inSANEly!). Exceptional lens optics produce a nearly perfect illumination pattern (in case you're an Ophthalmologist) and the two-click low-high button-cycle for the two lumen settings is very handy. Note that this "Pro" model produces you the low 15-lumen setting on the first click, then the 320-lumen 'dazzler' setting on the second: the other "Law Enforcement" model of this same body, the "G2X LE"\ reverses that switch behavior (we suspect the logic is "first let's blind the perp, then later we'll read a map in the squad car"). Apparently, the logic on the "G2X Pro" is more "let's sneak up on people first, THEN blind then". Element of surprise, one supposes. It's not hard to guess which one is for which audience.

The casing seems to be machined from a block of leftover M1 Abrams tank armor: it is unlikely that you'll break it unless you drop it out of the hatch of your sub-orbital SR-71 and it falls 100,000 feet onto granite (heat... it could happen! it's just not very likely). The rear section of the barrel can be twisted to ensure that you don't accidentally press the butt-end switch (twice) and inadvertently turn the light on in your pack or pocket. That could be A Bad Thing because the G2X Pro gets rather 'warm' if you leave it on for extended periods... we haven't tested this theory, but based on handling it after 10 minutes on, it might melt through a nylon jacket after an hour unattended (but hey... it'd make a great hand-warmer for antarctic camping trips!). It also seems to chew through the rather expensive '123 batteries it requires (we're looking for the rechargeable type as an add-on).

For nighttime field operations where you don't want to blind yourself (or just ruin your night-adjusted vision... let's say you're uh... an 'astronomy enthusiast'... yeah, that's the ticket...), we highly recommend a red filter ("Flip Up Red Filter for SureFire Flashlights with 1.25" Diameter Bezels"). Just remember: with the filter flipped open, and with this unit on the high-lumen setting, it's easily bright enough to blind… um… any "tourist" who might... y'know... stare directly down your barrel. Of your flashlight, of course. Or your scope. Uh... telescope, that is. Sure.


600 lumens


1 CR123A batteries required. (included)

  • Virtually indestructible LED emitter regulated to maximize light output and runtime
  • Two output levels - high of 600 lumens for maximum light, and low of 15 lumens for extended runtime
  • Dual-output tailcap click switch--press for momentary-on low, click for constant-on low, return to off then press or click again for high
  • Precision micro-textured reflector creates smooth, optimized beam
  • Tough Nitrolon body, anodized aluminum bezel


10 x 4 x 1.5 inches ; 1.1 pounds


1- Best flashlight I ever ever owned.
2- Incredibly bright.
3- Functional, durable housing material.
4- Thankfully only a single output mode


batteries are not rechargeable and can become a fairly costly maintenance item. Surefire does offer a rechargeable battery (and charger) separately, which may need to be my next investment.
