Product Description


Specially designed to keep your pool well lit this season. Our bulbs are made with thicker filaments and glass to last longer. Heavy duty heat shielding prevents damaging heat build-up and prolongs the bulb's life.

* Dimensions may vary slightly


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.

Just bought a house with an in ground pool. The light does not work. How do you know which light to order? Is there a name somewhere on the light assembly?

A  Answered on 5/2/2016 by InyoPools Product Specialist Hector F.

Yes usually once you pull the light fixture from the wall, rest it on the deck there is a label on the rear cone of the fixture that states the model.

Hi. We will need to know the make and model of the fixture in order to identify the lens gasket.
