Guess it's time for an update. I've long since moved away from the cheap Chinese lights, and now love and use a Zebralight SC600W every day. I feel like this could be the last flashlight I ever buy. Easily fits in my pocket, nice color tone, and goes from <1 lumen to over 650 if I need.

Pseudonomen137's mRad calculator is really nice...
Yeah, it seems like you've already assumed that position too! It's just a thread, so anyone can help, it just seems that a lot of the questions are directed at me so I try to get to them ASAP. Even though I forget sometimes. :P
