I had a floating rechargeable light/fountain. I took it back, the issue was with the filter on it tended to go towards the sides and spray water out of the pool. The 'light' show well it left a lot to be desired and the fountain only went up maybe 6". I forget the brand but it was more hassle than it is worth. I have a aqualuminator with a fountain, and that is ok at night. But there is 1 issue, I cannot put the colored lenses on with the fountain. But I kinda like the white. I hear they have a LED multi color version, I have 2 bulbs if one fries again(got 2 replacements from Pentair) I will try to retrofit it with the led. I saw instructions on this forum I beleive. Only other issue is I have not figured how to Pvc the aqualuminator, I don't want to mess the housing up.
Good luck
