This was a random buy. It's really useful in the garage and in the shed.

Lightweight, and works very well.

On highest setting, the light is bright and lasts for about two hours. Set at the lowest setting, it is the equivalent of a night-light, enough to find your way through a dark room, and lasted an incredible 170 hours in my test. One continuous week! The setting is continuously variable, and set to the approximate mid-range setting, it was reasonably bright and lasted a little over five hours. I will find these very useful for emergency lighting during power outages, and occasional use for patio lighting.
