The next big thing in underwater pool lights

After building your pool and enjoying it during the months or years comes the next step: replacement. There are three things you have to keep in mind when replacing underwater pool lights.

How to buy the right replacement for underwater pool light?

These are important things you should consider:

Voltage. This is the first element to take into account. For example, in the U.S most swimming pools are using 120 volt lights, although there are a few places in Maryland having other requirements. Be careful when selecting your pool lights; make sure you read the label before buying.

Cord Length. When buying underwater pool lights you need to make sure you buy a cord that is long enough to reach the junction box, in addition to 3 or 4 feet of cord coiled up inside the niche. The extra cord is needed so you can have enough slack to pull the light up on deck for bulb replacement or any other maintenance task you may require.

Niche Size. Something else to consider when replacing this product is that there is no standard size for niches and they all vary by an inch or so. The most common brands have different diameter in terms of light niches, which fit different sized underwater pool lights. For maximum results, please make sure that you are replacing the product with the same exact pool lights.


Our advice is that this procedure is performed by qualified personnel only. Remember that working with electrical wiring can be hazardous. Please, use an electrical test meter to verify that the power is off before you open the junction box and start replacing the underwater pool lights. In addition, read all instructions and make sure you have understood all the precautions need to handle your new lights before any installation attempt.

Study the owner’s manual for specific instructions and cautions. After that, start by turning off the power at the breaker panel conceived for pool equipment. If there is more than one breaker, then turn them all off.

When you are sure the power is off, drain the pool and locate the light junction box. Take into account that older pools with underwater pool lights may have the junction box located beneath the rear of the diving board, and in the case of the very old ones it may be located in the pool deck, beneath a steel plate.

Now you just need to remove the pool light from the light niche and cut the cord just behind the underwater pool lights disconnected from the cord. Inspect visually and close-up where the cord leaves the light niche.

Now it is time to return to the junction box and remove the saddle clamp that is holding the pool light cord in place. Make sure to grab the light cord firmly in the junction box, and then pull it straight up. We need to be careful in this step.

Replace the saddle clamp that holds the light cord in place at the junction box.

Coil up the excess cord around the new pool lamp and insert the underwater pool lights in the niche.

Please remember that the replacement of this kind of products should be performed by a qualified person, with experience with electricity. Your best option is to hire a well-established pool company.

Don’t make this silly mistake with your swimming pool lights

You should be very careful about repairing your swimming pool. There are many people that have committed the mistake of trying to repair the swimming pool lights by themselves and some accidents have occurred due to their lack of knowledge in terms of pool repair.

Replacing a bulb

This is probably the most common repair in swimming pool lights. First you need to pull the lamp out of the niche, and then remove the clamp band. Be careful with old, soft brass screws. Use spray lubricant first, and use the proper size screwdriver to make sure you don´t strip the head or even break off the screw head.

When the clamp or nuts or screws are removed, proceed to separate the lens/gasket from the lamp housing. In this step a flat head screwdriver is generally used which should be inserted between the gasket and the lamp housing. Next, pry the lens/gasket from the housing. In case you don’t have a new lens gasket, be careful with it. It is advisable to replace the lens gasket at the same time as replacing a bulb, but you can also reuse the old gasket, depending on its condition.

Repair leaking pool light niches.

This is probably the second most common repair regarding swimming pool lights. Concrete and vinyl pools generally use a light niche that resembles a sideways bucket with a small hole in the upper back for the light cord to run through. This port on the light niche is commonly connected to a gray pvc conduit, usually 3/4″ diameter. The conduit runs up towards the deck, then, it passes under the deck to a point where it can turn upwards and come up to a junction box, there, your pool light cord meets the power wires from the breaker panel. But after months or years of usage a conduit can leak, especially due to shifting pool or ground, or even freeze damage. The conduit immediately cracks or becomes separated from the niche. That´s why you need to check this when you open your pool and if you see that its water level is at the top of the swimming pool lights, then it means that your pool is leaking water through the pool light conduit and needs to be repaired.

In the case of leaking swimming pool lights you can use a big handful of pool putty – about half a package – in order to build a cone around the point where the light cord is placed. You can also use another method consisting in using a silicone product; however this is not recommended underwater.

If  you choose to use the silicone to repair the leaking through the swimming pool lights be careful not to shoot too much into the conduit, because it will make a future pool light replacement to be more difficult. The third method is to use a cord stopper, but the best method to repair your swimming pool lights is to call for the aid of the professionals. Please remember that you have to be very careful when working with electricity and water. Make sure you follow every possible safety precaution and turn off the power at the main circuit breaker when doing any kind of work related to swimming pool lights.
