Underwater lights are a standard fixture in all pools. Similar to a household light, pool light bulbs will need to be changed with time. To do so safely and efficiently, follow these steps on how to replace a pool light bulb below.

1. Shut off the power

Make sure that you turn off the circuit breaker for the pool light before you exchange the bulb. After the power is turned off, hold a non-contact voltage sensor next to the light switch that provides power to your pool light and test the on and off switch. If electrical voltage is present, then the sensor will react with an audible and visual alarm.

2. Remove the fixture out of the niche

To remove the light fixture, simply remove the steel screw at the top of the light and use a flathead screwdriver to remove the fixture. Once it’s removed, lift the light up onto the edge of the pool.

3. Take out the screws or clamp holding the lens

Once you have the light fixture on the pool deck, take out the screws or clamp holding the lens, and gently pry the glass 
from the front of the fixture. We recommend that you have a towel underneath the fixture while removing the glass to prevent it from shattering.

4. Unscrew the light bulb

After the lens is removed, remove the bulb by twisting it counter-clockwise. 
keep in mind that some spa lamps or small halogen lamps have small bulbs that need a push in and twist motion to remove. Be careful when removing the bulb, as old
 light bulbs tend to break at the base during removal.

5. Dry all interior surfaces

When the light bulb has been removed, use a cloth to dry all the fixture’s interior 
surfaces, then thread in a new bulb, specifically made for the fixture.

6. Briefly turn on the power

Before you reassemble the pool light, turn on the power for a brief 1 to 2 seconds. This will allow you to test the bulb and make sure that it’s working properly.

7. Reassemble the light fixture

Reassemble the fixture by attaching the lens back to the fixture using a new gasket (round rubber piece around the lens). Make sure the screws are screwed on tightly and that the lens is properly aligned.

8. Check for air leaks once placed underwater

Once you submerge the fixture back into the pool, check for air leaks. If there are no bubbles coming out of the 
light fixture, it is sealed. If there are bubbles, remove the fixture from the water to check the lens alignment and tighten the screws. Repeat this step until no bubbles appear when the fixture is underwater.

9. Place the fixture back into the niche

When you’re done ensuring that there are no air leaks, place the fixture back into the niche by lining up the tabs. Once in the correct position, push the
 fixture into the niche so it’s flush with the pool’s surface.

10. Test the light

Replace the top screw into the light ring and then thread it through the hole in the niche. Tighten the screws more so it creates a snug fit, and then test the light.

Remember to use proper-sized tools, so there is no chance of stripping off any of the metal screws, bolts, etc. On old
 fixtures, screws may break easily or be corroded from exposure to the water and chemicals.
