I got the pentair intellibrite 5g. It's pretty groovy. Like I've seen on other posts, the red is a bit dim; for the price they charge they should fix it. Otherwise it's perfectly bright for my pool. On white it's a bit brighter than the old light with two 100w halogen bulbs, and it's really white so the pool looks blue at night instead of green (although it does have various shades of green you can choose if you so desire).

Turns out the niche in my pool is an off brand according to the pool guy and moreover is not installed correctly - I guess the screw hole is supposed to be at the top (to screw the light in) but instead it's at about a 2 o clock position.

The pool guy actually charged me less for the light than I was able to find it for online and with labor it was 600.
