User Review: Petzl e+LITE
Price Paid: $22
The perfect union of form and function. This little guy is one of the most value-packed items you can stash in your pack, car, or anywhere you may end up needing hands-free lighting. Super lightweight, very bright on max white setting, easy to operate, and just plain cool to have on you.
The hat clip is durable, stiff and will aggressively grab onto any thin material (you can even clip it to clothing, cardboard, or paper). The plastic gimble is also pretty stiff, so it will remain in a particular position while you wear it on your head. Note the flat "base" is wide enough to set on a flat surface for lighting a cooking area, etc.
Petzl has pretty much covered every base with this light- even the battery cover has been designed so that you can unscrew it with the spring loaded "barrel" lock on the strap. Although the case isn't 100% waterproof, it is still very well designed. It is light, rugged, capable of being run onto a belt, and just perfectly sized to hold the light and strap.
I should add that brutes who like to manhandle things should probably avoid buying this light (not that I think it couldn't take your abuse, I just think you wouldn't be interested in something so small and refined).
