Hi all, Thought I would let folks know that I replaced our 500W incandescent bulbs in Pentair housings with this $139 option:
They use 35W vs 500W and are sufficiently bright to illuminate the whole pool at night (2 lights on each end of a 42' x 20' pool). It is fun to play with the various programs, but now we just leave it on a nice white/blue shade that is gorgeous. We have the lights controlled by a WiOn wifi connected switch which means I can more easily scroll through the various lighting options. Also we now have the LED lights on a program that turns them on for a couple of hours every evening.

In any case, these lights have lasted all season with no problems. They seem to be a much more cost-effective way to go LED than the Pentair OEM options. Just be sure to replace the seals if you switch out your bulbs.
