Pretty darn good!
I bought a pair of these for my fountain. I was hoping they would illuminate thf face of thr fountain, but they're not that bright. However, they do make pretty light to make the water in the basin glow.
ProsPrice, a zillion possible colors with the remote control.
ConsNot real bright, light doesn't shine out of the water onto something else. Remote is a bit tricky to use- must be right over the light to make it work. Uses 3 AAA batteries each. Not heavy enough to stay in place underwater.
