Changing a swimming pool light bulb might seem tricky, but with the right tools and safety steps, it’s a task most pool owners in South Africa can do themselves. Whether you’re replacing a broken bulb or upgrading to an energy-efficient LED light, this simple guide explains everything you need to know.
Main Takeaways
- Always switch off power at the breaker before starting.
- Use a pool-rated or LED bulb for energy savings.
- Replace the rubber gasket if worn to prevent future leaks.
- Test the light before screwing the fixture back in.
Tools & Materials You’ll Need
- Screwdriver (usually Phillips)
- Dry towel or cloth
- Replacement pool light bulb (preferably LED)
- New rubber gasket (if needed)
- Pool light lens cleaner (optional)
Step 1: Turn Off the Power at the Breaker
Before anything else, turn off the electricity at the circuit breaker connected to your pool lighting system. This is critical for your safety. Never work on underwater lights while electricity is flowing — it’s a serious electrocution risk.
Step 2: Remove the Pool Light Fixture
Locate the single screw that holds the light fixture in place. Typically, this is found at the 12 o’clock position on the light housing. Using a screwdriver, carefully unscrew it. Then gently pull the entire fixture out of its niche. You’ll find that it’s connected by a long waterproof cable, giving you enough slack to rest the light on the poolside without disconnecting it.
Step 3: Open the Light Fixture Safely
Once the fixture is out of the pool, place it on a towel to avoid scratches. Unscrew or unclamp the lens cover to access the bulb. You may also need to remove a retaining ring. At this point, check for any trapped water — this might be a sign of a damaged gasket.
Step 4: Remove and Replace the Bulb
Carefully unscrew the existing bulb using a cloth or glove to avoid skin contact. Then insert your new swimming pool-rated bulb or LED equivalent, ensuring it’s a correct match for your fixture. Avoid touching the new bulb with bare fingers — oils from your skin can reduce the lifespan of the bulb.
Step 5: Inspect and Replace the Gasket if Necessary
Check the condition of the rubber gasket that seals the light. If it looks cracked, brittle, or worn, replace it. A poor seal can let water in and damage the new bulb. Reassemble the light, making sure all components are dry and sealed tightly.
Step 6: Test the New Bulb
Gently lower the light fixture back into the water without securing it. Then turn the breaker back on briefly to test the bulb. If the light turns on, turn the power off again and reattach the light fixture to the wall securely.
Step 7: Reinstall the Fixture into the Pool Wall
With the light confirmed to be working, line up the fixture in its niche and reinsert the retaining screw. Make sure the cord is neatly tucked away so it doesn’t float into the pool.
Benefits of Switching to LED Pool Lighting
While you’re replacing your bulb, consider switching to energy-efficient LED lights. These lights offer several advantages:
- Lower electricity bills over time
- Longer lifespan, up to 50,000 hours
- Brighter, vibrant colours and colour-changing options
- Eco-friendly with lower heat output
Many Cape Town pool owners are opting for LED upgrades to make their swimming pools more efficient and stylish.
Safety Tips for DIY Pool Light Repairs
- Never work on a pool light unless the power is 100% off.
- Use proper PPE (rubber-soled shoes, gloves).
- If unsure, call a certified pool technician — especially if wiring appears damaged or corroded.
