I bought a Pentair Intellibrite 5g last year at which time I also considered the Hayward ColorLogic. I looked briefly at the SaVi lights and I can't remember why I decided against them quickly. Here's the thread I posted about it, which also includes photos. http://www.poolforum.com/pf2/showthr...ard-Colorlogic

I can't say that the Pentair is any better than the others because I've never seen them in person, but I can say that I am very happy with the pentair. It's brighter than a 200w halogen, and changes colors to boot!
