I purchased half a dozen of these last time they were on sale. They run for a ridiculously long time on 4 AA Duraloops. I have not used them as headlamps but instead as a safe light a closet light and set on tables during power outages. For $1.49 you can't go wrong.
Talk about cheap! (Price and at least the appearance of build quality.) How bright are these things? Any idea? Floody? I'm wondering on camping use - table top, strapped to a tree aimed down onto campsite, etc. . .
