Embarrassment? I'm all function first, form later...unless I'm cold.

I keep a Gerber Infinity Ultra in my pocket 24/7 (I've never liked the prospect of locating a coin battery for my EDC light should the battery fail at the least opportune moment...AAs are everywhere). Sometimes I even put my Petzl e+Lite on my belt...especially if I'm camping or hiking since I use it all the time in that setting.

Good to see somebody is testing the longevity of these lights. I'll be curious to see the results of your full scale test.
