I can't wait to use it.
I will add one other word of caution - if you leave the batteries hooked up to the lights when they're off, it WILL drain the batteries. I experienced this myself this spring when I found myself out on the trail and went to flick on my lights only to find them completely dead. This fall I was trying to half drain one of the batteries (a 4 cell) and I left it hooked up to one of my 400L's (not on) and in about 4 days it drained to half capacity (according to the built in battery gauge thingy that blinks when you turn the light off).
