I've bought several different toilet lights, both USB and battery powered. USB doesn't seem to hold up anymore. Other models work fine with a charge or two, and then the colors don't work at all. I've used rechargeable nickel cadmium batteries with one of these in packs of six and they seem to last quite a while on a single charge. I'm not exactly sure how to change the brightness and maybe you can't, but they are bright enough for me. The fact that you get six of these means you can use them in more bathrooms and not have to buy them as often. It's good value. If you've never used one of these, don't like messing around with a switch, and want to save energy, give it a try.
