I've been on a flashlight tear lately, learning a lot in the process. I recently aquired a Surefire L4. A few years ago I would not have believed that any flashlight is worth what this one cost, but it's very, very impressive.

It seems to be like some other items, you don't miss not having it until you try it EDC and see how handy it really is.

Of course, that wasn't so much the case just a little while ago, before you could easily pocket a really powerful, reliable light.
