POOL & SPA LIGHT LENS GASKETS
Remember when replacing your pool or spa light bulb it is very important to replace the lights lens gasket. After long use, heat, and harsh chemicals, the old gasket is probably compressed, and if it doesn't fail immediately, it might fail before the next bulb change. Click here for Pool Light Lens Gaskets

This was a great low cost replacement for the underwater light in the pool. Product was exactly as advertised. Website was easy to use. The light bulb arrived quickly and in perfect condition. Website also had easy to follow instructions to replace the bulb. I also ordered a rubber seal around the light based on the instructions on the site.
