Krill Lights: Do you use them?

I have a couple or the 180* Extreme (green and red) and I really haven't used them much. The red stays in the truck.

I haven't been camping in a while admittedly, and will probably use them then.

In the meantime, what do you use your Krill lights for?

I use one every night in my son's room (or ours if he migrates to our room (6 months old))- puts out enough light to navigate by and enough light for him to see that it's not "real" dark if he wakes up. I use Lithium AA's (Energizer's) in it and I get about 65 hours out of them as opposed to standard alkalines at about 50 hours. Conservatively, I've got about 1500 hours on it so far without a glitch (I've got other glitchy ones however). The green seem the most robust from what I've seen and sold over the years. I have a 180 Extreme green in each car's kit bags with lithiums, along with a multitude of other gadgets, knives and lights.
