we are also looking at the requirements for pool lighting and as far as i can tell in nec. 680.22 (b)1. I will have to be no less than 5 feet from the inside wall of the pool and 12 feet vertical from the maximum water level. Am i understanding this correct and does it apply to commercial applications. (we are building a condo where the pool is above the first floor and are worried about the corridor lighting being to close).
