I bought a pair of these a month ago on promotive.com. I had not used them until this week except for extra lights in my driveway, and now I am impressed. I was in fort Hunter Liggett for an op this week. We were not tactical so we lived in a plywood building, but there was no power. I brought two of the light a life's. I had an old motor cycle battery that I attached a 12 volt socket to. I plugged the lights into the battery using the included adapter. The results: outstanding!
The light itself is also magnetic and can be attached to any metal surface.
Pro: low draw, bright and adjustable, multiple ways to mount. Can chain multiple lights together from a single power source.
Con: needs a goal zero battery or 12 volt cigarette type source.
