OK, do not laugh, I bought this as a nightlight for the bathroom at night for my cats ... So They Can See What They're doing When They need to visit the litter box. The bathroom does not have a window, so it's pretty dark in there. Yes, I'm love my cats very much :) Well, it gets two paws up from the cats :) it does a great job of providing some dim and colored light in the bathroom, and I like it so much, I might buy more Hanes my long dark corridor, so I can see where I'm going at night ... instead of tripping and falling over everything. Ah well, cats first. The color revolves through a spectrum, it fades from one to the next very Gradually, it's a really pretty effect, much like a disco. I did wonder why the cats were spending so long in there, and I did question all the empty cocktail glasses and empty beer bottles littered everywhere ...
