After much effort charging the batterier on the four lights I bought (they all came uncharged contrary to advertisement), I screwed them in place, turned them on just before my party and they lasted 3 houors!! Advertised as 9 hours. Now I have to unscrew them, charge them and screw them back onto the frames!! Easier to have an electrician accomodate an electric light! Furthermore, the light bulb hardly did the job.

Bulb doesn't put off enought light. Looks like it is on dim.
