How do you approve an above ground light inside the zone by code? (not "underwater")
The only time I have seen fiber illuminators they get installed outside the zone and "fibered" in. That makes everyone happy so the contractor does it that way. He gets to sell another few feet of fiber too. If you are inside that zone with a light, I am really looking for something that looks like 680.23. The same thing goes for rope light, landscape lights or anything else. That is the advantage of fiber, you can put your illuminator "out there" and still pipe in light for borders, accents, spots and anything else you would have done with rope, Malibu or whatever.
I really can't think of any pool equipment besides a light, and maybe a power cover, that needs to be in the zone.
