I agree - that Intellibrite light does seem to have some problems, to the point there is already a 3rd party that builds a new LED board and has a how-to for repairing them.
If your PB will let you choose any light and not just what they stock then I'd consider the Halco/J and J Electronics up front. I have 2 years experience with the Spa LXG color change (LED) bulb, it still works great and just about 2 weeks ago I installed the newer Pool LXG color change w Pure White (LED) bulb in the pool. Very happy with it so far too.
My pool started off with incandescent bulbs in both 5 years ago and both of those burned out. So moved up to the LED bulb from J and J since it was a direct replacment screw in bulb, it was LED and the Pentair Easytouch will control the colors just like they would the Pentair LED bulbs which were way overpriced from the PB 5 years ago.
