I have two color logics in a 16x34 darker liner pool. In a lighter lined pool your lights will look brighter, in my pool its more of a glow, its still bright, but not as bright as a pool with a white or light liner (plaster). Another benefit of LED's is they use less energy and last longer. I like the color patterns that favour the blues/pink (sangria they call it) and green, the red is a bit weird and not really bright enough. I also like the remote that the color logic comes with, so convenient to turn it on when you are inside to get that mood light going.
Alas, they have closed my pool today, so all I can see now is a dark winter cover.
