There are many types of pool lights and they vary greatly from company to company. For reasons such as the long life of LED pool lights, only some pool lights have replaceable light sources. Currently, the most common standards for replaceable pool light bulbs are PAR56 and E27. You can learn more about pool light sources by reading LED Pool Light Bulbs: A Complete Guide. In addition, you also can consult with your retailer or pool light manufacturer.


Before pool light bulb replacement, we need to be fully prepared so that we will not be in a hurry when changing the light bulb. Have the tools you need to change the bulb ready. Screwdriver, test pen, replacement light bulb.

Pump Water

Draining a portion of the pool water allows for easier replacement work. This is not necessary, but very useful for novices.

Turn Off The Power

When you’re done pumping, turn off the power to the pool. The pool power can be found on the power distribution box. After finding it, turn off the power. After turning off the power, try turning the light on again to confirm whether the power is turned off. If you can’t find pool power, your safest bet is to turn off the main power in your home. Then repeat the above method to see if you have turned off the power.

If it is a recessed pool light, reserved light wires will be in the pool light niche. At this time, you can unscrew the pool light and gently pry out the light. Then directly pull the light to the ground for the following work. If it is a wall-mounted pool light, you can loosen the wire on the other end after gently prying the pool light so that you can slowly pull out the light wire and then pull it to the ground.

Replace The Pool Light Bulb

The next step is to screw the screws. Some of the screws on the lamp cover are cross-shaped, and some are in-line. Therefore, prepare all possible tools at the beginning to ensure that you can get the tools you need at your fingertips and avoid wasting time. Take a suitable screwdriver, remove the screws from the lamp cover, put it in a safe place, remove the lamp cover, and put the screws together. 

Some bulbs are screw connectors that can be twisted and unscrewed, and some have wires attached, so take extra care when removing the bulb. When a wire is exposed, first use a test pen to test whether the wire is live at this time, and then replace it with a new bulb after confirming the safety.

If there are dirty things in the lamp to be cleaned in time, the swimming pool lamp used for more than ten years may also have internal water corrosion. If the corrosion is severe, even if we do pool light bulb replacement, it may be corrupted in a short time. In this case, replacing the pool light with a brand new one is best.

Put The Pool Light Back

After replacing the wick, put the inner collars of the lens back one by one. Then place the lamp housing and re-tighten the screws. For the recessed swimming pool light, wrap the light wire in circles, put it back in the alcove, fix it, and screw it on. For wall-mounted swimming pool lights, you also need to go to the other end of the wire after setting the light. Gently pull the wire that was pulled in just now, then connect it to the power supply, and stick the interface with insulating tape.

Organize tools to avoid missing screwdrivers, screws, etc. If you accidentally kick the fixtures into the swimming pool or are blown into it, it will cause safety hazards.

After doing all the above, turn the power back on and see if the pool light works properly. At the same time, use a test pen to test whether there is leakage around the pool light. After everything appears to be expected, our pool light bulb replacement is complete.
