Pool is drained and demo has started. Now it looks as though my lights (large pentair style 11" and smaller spa size that won't be replaced) do not have niches. I know the pool is old, but I wasn't expecting this. Now that I've bought a replacement pentair LED, should I return for a nicheless light? PB says too hard to install a niche, which seems about right. But then he also recommended to skip the niche, so even more confused. Also discovered nothing was grounded, not the lights or the pool pump. So, lots of fun.
