How to Safely Replace a Pool Light

Replacing a burnt-out pool light can be frustrating, especially if you think you have to drain your pool to do it. In reality, most pool lights are designed to be easily replaced without draining any water. Replacing a pool light should be as simple as replacing any other light bulb in your home or property. Before you start this project, it’s a good idea to read through these steps to ensure you know how to safely replace a pool light. While it’s best to have a licensed pool technician perform this replacement, if you want to do it yourself, follow the instructions below.

Start with the Right Replacement Bulb and Gasket

The first step is to purchase the correct replacement bulb and gasket for your pool light, based on the existing bulb and gasket. Unfortunately, there are many different types of pool lights, and installing the wrong one in your existing pool can put you and others at risk of electric shock. Never replace a bulb without a new gasket. The easiest way to find out what type of bulb you need is to check the information left by your pool builders. This should provide you with details such as the manufacturer, model number, voltage, and wattage of the bulb.

If you can’t find this information, you’ll have to wait until you can remove the existing bulb from the pool to get that information from the back of the light housing itself. This requires you to move on to the next step.

Turn Off the Switch that Controls Your Pool Lights

To protect yourself from electric shock, make sure you completely shut off the power to your pool light before proceeding with the bulb replacement. Some pools may have their own dedicated switch box, while others may share a switch box with the rest of your house. Regardless, locate the switch that controls your pool lighting and turn it off.

Remove the Existing Light Fixture and Replace the Bulb

With the power to the lights turned off, you should now be able to safely remove the light fixture from the niche on the side of your pool. Depending on the type of fixture you are working with, you may need to use a flathead screwdriver or another type of hand tool. Once the fixture is removed from the pool, there should be enough wiring behind it for you to pull the fixture onto your pool deck, remove the lens cover, and unscrew the bulb. Never attempt to replace the bulb in the water.

If you haven’t purchased your replacement bulb yet, make sure to take the burnt-out bulb and gasket with you so you know exactly what type to buy. It may be a good idea to keep these lights and gaskets in stock. Once you have the replacement bulb and gasket, screw it in and reinstall the lens cover.

Replace the Fixture and Restore Power to Your Pool Lights

Once you have finished installing the fixture into the niche, ensuring the cord is properly seated, turn the power back on for the switch that controls your pool lights. You should now have working lights throughout your pool. You will also want to check and make sure no air bubbles are coming out of the light you replaced, as this may indicate an improperly installed gasket. If you see any air bubbles, turn the power off again and try reinstalling the gasket. Be careful to properly align all screw holes and tabs of the fixture when reinstalling it.

As you can see, replacing a burnt-out pool light bulb doesn’t have to be a difficult task. The most important thing is to make sure you purchase the correct replacement bulb and gasket and ensure the electrical power to your pool lights is turned off before proceeding. However, we always recommend using a licensed pool technician to perform this task.

Having working pool lights allows you to enjoy your pool even when it’s dark, so it’s a good idea to keep replacements on hand. For more information on pool maintenance, contact the team at Summerhill Pools today.
