Surefire System
Aug 25th, 2010 by C. Alexander Leigh

Why do we win wars? We have the best flashlights. My first SureFire was a A2 which was basically an incan with a 3 LED red backup. It was great; the incan had great throw and you could use the LEDs for reading, maps, protective illumination (handy around burning man so you’re not a darkwad, I’d just wander the playa with it hanging around my neck). The problem with my A2 was simple: I lost it.
A period of mourning later and some serious research, I ended up buying a C2L. I promptly replaced the engine with a Cree XP-G drop-in from ThruNite producing something under 300 lumens, thereby creating a Fenix flashlight for three times the price. I chose the C2 over the M line because the shock isolation bezel causes some heat dissipation problems for the brighter drop-ins, and the C2 gets you into a smaller head more suited for heat transfer. And it does get hot.
The real benefit to running SureFire over a Fenix or a lot of the competitors is the P60 drop-in engines are so common, that you are basically future proofed. New LED coming out tomorrow from cree? No problem, you’ll probably be able to pickup a drop-in for thirty bucks. Additionally, the SureFire flashlights (if you are careful) are completely modular.
None of this helps my weapon situation though, and I was lucky to find a great deal on a used surplus M951 system. This provided the millenium series shock bezel, a picatinny barrel, and the clicky tail w/ remote as well as the IR filter, very handy for… I don’t know what. Now I need nightvision goggles.
In the above kit I now have an incan P60 (useful for throwing IR-only w/ the pictured filter), a P60L medium intensity LED, and the high-intensity Cree. I’m shopping for a ridiculous trophy drop-in (>1000 lumens) and meanwhile everything you see in the picture is interchangeable. Thinking about going with some of the higher-cap rechargable (2700mah ea) cells, and there are a few people making barrels that fit that, or else I can get these bored out.
In terms of the ThruNite this dropin has a great, affordable, clean throw, is super bright, but be aware it’s a bit bigger than the standard P60 engine that SureFire produces. It fits fine in the C2 head (although it doesn’t screw down 100% of the way, but this has no impact on waterproofness or anything else), and it’s tight bordering on not working on the M951 barrel adapter. Your mileage may vary!

Wait, when did we start winning wars again?
Troll.
OK, well, setting aside the question of whether anything the US has done militarily in this century fits any definition of winning, and also the question of how fundamental the amount of light flashlights emit really are to those enterprises – that’s a totally sweet flashlight.
Also: trolled.
A flashlight that is?
I stupidly thought it is a laser-controlled target painter which magically homes in the flying lead on selected targets.
I am experiencing flashlight envy. Le Grr.
Red that is an easy enough problem to solve.
Yes, most of my ‘problems’ can be solved by throwing some money at them.
