How Long Does A Pool Light Last?

The lifespan of a pool light depends on the type of bulb used. Incandescent bulbs, which are the traditional choice, typically last around 1,000 hours. Halogen bulbs, the next evolution of incandescent bulbs, have an improved lifespan and can last between 1,500 and 2,500 hours. On the other hand, LED lights are a more efficient and long-lasting option, lasting at least 20,000 hours. Some LED manufacturers claim even longer lifespans.

To put this into perspective, let's assume you use your pool lights for 5 hours every night. With this usage, you can expect the following lifespans before needing to replace the bulbs:

• Incandescent: 200 days
• Halogen: 300 days
• LED: 4,000 days (approximately 11 years)

Keep in mind that these estimates are based on regular usage, and you may not use your pool lights every night of the year. If you only use your pool lights half of the year, you'll be changing incandescent or halogen bulbs roughly every two years, while LED bulbs can last for 20 years or more.

How To Change A Pool Light Underwater?

Contrary to popular belief, you don't have to drain your pool or change the lights underwater. According to NEC regulations, pool lights must have enough cable hidden in the recess behind them so that you can lift the light out of the water once unscrewed. To replace a bulb, follow these steps:

1. Switch off the power.
2. Unscrew the light fixture.
3. Pull the light away from the recess, unwrapping the cord if necessary.
4. Lift the light to the poolside.
5. Remove the light cover, which is usually held in place by a gasket.
6. Unscrew the old bulb and replace it with a new one.
7. Check the gasket for wear and consider replacing it.
8. Seal the light by holding it underwater for a few seconds. If bubbles escape, the seal is weakened and needs replacement.
9. Replace the cover and place the light back into the recess underwater, tucking the cord away.
10. Screw the light in with one screw initially, then turn on the power and verify it's working before adding the remaining screws.

If you need to replace a sealed LED light or switch to LEDs from an older fixture, it will require more extensive work, such as feeding the new cable through existing conduits under the ground. Refer to a specialized guide for detailed instructions.

Should I Replace The Pool Light Bulb With LED?

Upgrading your old pool lights to LED lights offers several benefits that make it a worthwhile investment. Here are some reasons to consider replacing your pool light bulbs with LEDs:

1. Energy Efficiency: LED lights use significantly less energy compared to halogen or incandescent bulbs. This results in lower electricity costs. For example, a set of four LED lights can save you around $145 compared to halogens over 1,000 hours of usage.

2. Long Lifespan: LED lights have a much longer lifespan than traditional bulbs. This eliminates the need for frequent replacements and reduces maintenance efforts.

3. Brightness Options: LEDs can offer a range of brightness options. While most people prefer a gentle glow for pool lights, LEDs allow customization in millions of shades, giving you more control over the ambiance.

4. Environmental Impact: LED lights are more eco-friendly due to their energy efficiency and long lifespan. By switching to LEDs, you'll be reducing your carbon footprint.

Considering these benefits, it makes sense to use LED lights for both new pool installations and upgrading older lights.

How Much Does it Cost To Replace Pool Lights?

If you're replacing the light bulb within an existing pool fixture, it can typically be done as a DIY job. The only cost involved would be the price of the new bulb. Halogen bulbs range from $10 to $30, while LED light bulbs can cost between $50 and $70.

If you decide to replace the entire fixture or require professional assistance, hiring an electrician is an option. The average cost of hiring an electrician for pool light replacement varies between $115 and $175, excluding the cost of the lights themselves. Keep in mind that these costs can vary depending on location and individual electrician rates.
