Troubleshooting Problems with Underwater Pool Lights
If you own some underwater pool lights, then you may have some problems getting them to work all of the time. If your pool lights are not working correctly, then you can either call in a specialist, and see if they can find the solution to your problems, or you can try and fix it yourself by performing some basic troubleshooting. Looking at the rest of the lights around your home, you should notice the immediate differences between the two sets. The underwater pool lights are designed to work underwater, which can cause lots of complications in the wiring, and this should be the first thing that you look for.
Testing the Underwater Pool Light
You can take the light out of the water in order to test it, but you will need to remember that an underwater pool light can blow the bulb if you don't place it underwater when you turn it on. This is due to the fact that the lights are watercooled, and they will overheat if they are not in water. Remove the screw which holds the light into the niche, and then remove the bulb before replacing. Turn the light on and off in a low bowl of water, and see if removing it from the pool has helped in any way.
Removing Dirt and Debris
If the pool light is not affected by the change from the pool to the bowl of water, you should carefully examine all of the parts to check for signs of debris. There is a small amount of water algae which builds up inside the light niche, and this can prevent the light from turning on and off, and can also cause the bulb to blow underwater. Remove any dirt and debris from the light, and clean thoroughly.
Check the Electrics
Just as with a normal light, when it stops working you need to check out the electrics. Start with the circuit breaker for your lights. If this has popped out, then dry pressing it back down, and then look at the lights in the pool. You may find that one of the bulbs has burst, and triggered the circuit breaker. You should also check that there is no water in the light, as this can cause the breaker to fail, and then not properly reset. You should pull out the light and check.
You can also replace the bulbs in your lights in order to check whether this is the problem. It is not a good idea to try this bulb in your pool, so consider that you may have to install it in the bowl of water, and then transfer it to the pool once you know that it is working. Take your light into the pool, and screw into place carefully. You should lower the water level while you are installing the light, and then raise it when you are no longer near the pool.
