I'm using the Tactician as an EDC, get a good 16650 battery and you're good to go. If you want to mod it there's a factory of lumens that makes a lot of different Surefire parts so you can make it the way you want.
I own many SF lights and recently bought a Stiletto Pro and really like it. When I first saw them online I wasn't sure what to think and dismissed them as a gimmick light. That was until I handled one at the local fun shop, after that I had to have one. It's my favorite light now. No it's not a tactical light but it makes a great EDC. Fits in the pocket great, I love the controls and very bright. Not cheap but worth it in my book. In my humble opinion you get what you pay for with SF.
The EDCL-2T gets too warm for me. 5 amp draw on a pair of regular batteries did not set well with me. SureFire says its safe, but I am reminded that once upon a time Ford said BroncoII's don't easily roll over too. Samsung said their phones don't explode and Toyota said their throttles don't get stuck.
But I tell ya what, that sucker throws a beam a country mile. Easily ID stuff 2 football fields away. I used a 16650 in it that throttled it way back but still allowed a bunch of light out front, but the low was nowhere near as useable. I'd guess 600-700 lumens on the rechargeable. Not bad at all compared to the backup lights of before, yet you lose that whole "yee hah" feeling of the full output.
