I have 2 color logics in the pool and one in the spa. We have a dolphin blue (light blue) mini pebble finish. The LED's are definately not as bright as a 500W standard pool light. The colors are nice, I like the deep blue and the slow color wash options. They are bright enough IMO to see at night in the pool but it would be nicer if they were a little brighter.

I don't know anything about the SaVi so I can't comment on it, but if it's brighter than the colorlogics and has similar capabilities I would probably go that way assuming it's a quality light.

good luck, let us know how it works out.
