Right now I have 40 solar garden lights charging on the windowsill of my computer room. At night I turn them around so they light the room, hall and stairs nearby. I replace the AAA Ni-MH battery on some of them following a cloudy day with ones I have charged in a charger. I modified most of these solar garden lights so they blink or fade red, green and blue but a few are the original continuous white.
The solar garden lights were cheap Chinese ones and made of plastic, not stainless steel. I bought 10 then returned the ones that worked poorly. Then I replaced them with another 10 and returned more over and over until I have 40 that work pretty well.
