How to Change a Pool Light Bulb
Swimming during the day is a blast, but nighttime swims have their own charm—the water is warm, the night sky adds a magical touch, and there’s no worry about sunburn. But, of course, none of that is enjoyable if your pool lights aren’t working. Even just one burnt-out light can dim the whole experience. Luckily, replacing a pool light bulb is simple! Let’s walk through the steps, from choosing a new bulb to testing it out.
Why Replace Your Pool Light Bulb?
You might need to change a pool light bulb if it’s gone out, or if you’re ready to switch to a brighter, more energy-efficient option. Upgrading to an LED pool light can help you save on energy costs while enjoying vibrant illumination. Many LED pool lights even offer color-changing options, adding a unique effect to your evening swims and gatherings.
Should You Go Pro or DIY?
While changing a pool light bulb is generally easy, it does involve handling water and electricity. Safety is the top priority—if you’re at all unsure about handling electrical tasks around water, consider hiring a professional to ensure the job is done safely.
Tools and Supplies You’ll Need
If you’re ready to go the DIY route, here’s what you’ll need:
- Replacement pool light bulb (compatible with your pool’s light housing)
- Replacement lens gasket
- Phillips and flathead screwdrivers
- Multimeter (to ensure no current is present)
- Dry towels (a few for cleaning and drying parts)
How to Replace Your Pool Light Bulb in 11 Steps
Follow these steps carefully to replace your pool light bulb:
-
Turn Off the Power
First and foremost, turn off any electricity to the pool area. Double and triple-check that there’s no power reaching the light to avoid risks. -
Optional: Lower the Water Level
To make the job easier, consider draining a little water from the pool, enough to expose the light fixture if necessary. Remember, you’ll need to rebalance the water afterward. -
Remove the Pilot Screw
Find and remove the screw (usually located at the top of the light fixture) with the appropriate screwdriver. -
Carefully Pry Out the Fixture
Once the screw is removed, gently pull the light fixture out of its place. You should have enough wire slack to lift the fixture onto the deck. Place it on a towel to keep it clean and scratch-free. -
Check for Current
Before touching any wires, use a multimeter to confirm no power is flowing to the fixture. -
Disassemble the Fixture
Carefully take apart the lens, lens gasket, and face ring by removing the screws or clamps. Keep track of each component and avoid doing this directly over the water to prevent debris from falling in. -
Remove the Old Bulb
Unscrew the old bulb with a towel for grip and carefully take it out. Wipe away any dirt from the fixture with a dry towel. -
Insert the New Bulb
Place the new bulb in the fixture. Tighten it securely, but avoid overtightening, which could cause damage. -
Test the New Light
With the bulb installed, turn on the power briefly to ensure it works. Remember, pool lights aren’t meant to stay on outside of water, so keep this test short. Then turn the power back off. -
Check for Leaks
Place the fixture back in the water and look for any air bubbles that may indicate a leak. If you see any, take the fixture back out, dry it off, and reassemble it carefully before testing again. -
Reinstall the Fixture
Push any excess wire back into the wall, line up the screw holes, and secure the fixture in place. Once the light is back in the wall, turn on the power one last time to make sure it’s working.
Enhancing Your Pool Lighting Experience
With your new light installed, you can enjoy a brighter pool at night! Upgraded lights like LEDs can bring fun effects to your pool with color options, perfect for evening get-togethers or a relaxing solo swim. Plus, now that you’ve learned the process, future replacements will be even easier.
