Pool Lens Gaskets

There are many bulb types and gaskets available so make sure that you purchase the appropriate parts for your light fixture. To guarantee that you purchase the correct parts you will want to gather the manufacture name, model #, voltage and wattage of your light, this information can be obtained from the sticker on the back of the light housing this is typically located where the cord of the light attaches to the light housing. You will need to replace your gasket to ensure the proper seal of your pool light.

Step Two
Gather the following items.

  • Phillips and flat head screwdrivers
  • Circuit tester
  • Dry towel

Step Three
Locate your circuit breaker box and shut off all electricity to the pool area. Use a circuit tester if you're not positive that all of the electricity is off.

Step Four
Locate and remove the screw at the top of the light, this is called the pilot screw.

Step Five
Pry the light fixture out of its casing, commonly referred to as the light niche or can. Your light should have enough extra cord so you can bring it up and lay it on the pool deck. Note how the excess cord is stored as you will want to store cord similarly when reinstalling the light housing. Take the glass lens out of the fixture by removing the screws or clamps. Corrosion may have occurred so use care and the correct tools.

Step Six
Unscrew the light bulb with a towel using great care.

Step Seven
Find a friend to watch the light while you briefly turn on the electricity. This is to see if the bulb actually works. These lights are not made to be turned on out of the water, so this has to be a quick check.

Step Eight
Screw the new bulb in securely, install new lens gasket and reassemble the lamp fixture. Check for leaks by placing it underwater. A few bubbles may float up, but water should not be coming from the sealed outer edges.

Step Nine
Restore the lamp unit and the excess cord to their original positions. Make sure the screw holes line up correctly.

Step Ten
Turn your electricity back on and enjoy swimming at night once again.

Tips & Warnings
If you can kneel on the coping and reach the light you do not have to lower the water level. If not, drain the pool water or jump in.

Any parts that are crumbling or corroded should always be replaced.
