occasionally I purchase an item just to "check it out"... examples would be the Goal Zero 7w panel, and the Nitecore charger and 18650s cells....compared to some previously required classes, the education is cheap...the switch to AA Eneloops for my emergency hurricane electronics and lighting came from lessons learned...I don't really need an SBR, but it was fun to build ... while I have a Malkoff module for an old 6P, the rest of my P60 lights are G2s off the prize table, or Solar Force hosts, with XM L2 or XP-G (for the 18650) modules (foil wrapped)

on the practical side, I'm a retired high school teacher, and still like to attend athletic events at school...as a gun free zone, a mongo candlepower pocket light is a legal deterrent option... if you have accidentally flashed yourself, you know how disorienting it is for a couple of minutes
