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
