I used to EDC a Surefire P6 LED, but have since switched to a 5.11 L2 (LED). The Surefire was ON any time, and there's a lot of times you don't need BRIGHT in a flashlight. The L2 is also a (2) 123A flashlight, but it's 220 lumens on bright, like 10 lumens on low, and has a strobe. The cap screws all the way on, and it has a safety for when it's packed or something. Standard deal on operation... Hold it down a little bit and it comes on momentary, and down farther and it clicks and stays on. Flash the momentary once and go on, and it's on low. Flash momentary twice, and the third time it's on bright strobe. Any time it's been on, and is turned off, when you turn it back on, it always starts on bright. When you click it on once, and click again to turn it off, it turns off (no cycling through the different modes like cheap lights). The LED is apparently a CREE.
More than the operation that I like better, they're a little bit smaller in the head, and they're a lighter weight light than the P6, so they really work well in the pocket, and don't feel like carrying another full mag or anything.
They're like an $80 flashlight, I think, but I saw them at Gander Mountain for like $50 the other day. I have not looked online to see who is selling them for what. I got this for like $35 at the Grainger show, but I would (and probably will) buy another one at whatever they sell for ($50-$60).
Also has a little bit of a strike bezel.
The LED is also regulated, so it stays the same brightness for a long time, before it starts to get dim, and you know to change batteries.
