Are light niches standard for the most part? I ask because my PB installed a Pentair Large Plastic Niche (P/N: 79206700) for the pool but used a Jandy Small Plastic Niche (P/N: PLNICSM) in the spa. The PB is providing a Pentair Amerlite for the pool and a Pentair SpaBrite for the spa. I assume we won't have any issues with the Amerlite as it will be going into a Pentair Niche, but what about the SpaBrite? Will it fit correctly in the Jandy niche? I'm also thinking about ordering a Pentair IntelliBrite Color LED pool and spa light, would those fit in the Pentair and Jandy plastic niches? I'm super OCD about things matching and being perfectly mated. I actually just placed an order for the small Pentair Plastic Niche (P/N: 79206600) on amazon. I hate to be a pain, but I think I'm going to ask the PB to change it out in place of the Jandy... Am I over thinking this?
