Crutchfield Customer Review (What's this?)
For the money this is a pretty good product. I use it to light my chicken coop at night. It provides sufficient light to allow me to observe the chickens at night. I am not sure of the potential life since it seems somewhat flimsy. It does provide light all night without the batteries going dead even after a cloudy day.
Pros: Long light life
Cons: light weight plastic likely to break
