Reason 1: Incorrect bulb voltage
We sell two voltages of pool lights, a 12V and a 120V.
If you have a 120V system and install a 12V light bulb, the light bulb will blow out when the power switch is turned on. Most pools in the United States are 120V. Sometimes people buy the 12V bulb to save on energy costs, but don't realize that in order to use a 12V bulb in their 120V system, a step-down transformer must be installed.
If you have a 12V system and install a 120V light, the light bulb will be dim, flicker or may not illuminate at all when the power is turned on.
If you determine you have bought the wrong voltage bulb or you need to return the light for any reason, you can send the light back to Amazon within 30 days. If 30 days have passed, please go to exchange.life-bulb.com to view the easiest and best return/exchange method.
Reason 2: Water in light fixture
The pool light fixture was not sealed properly and water leaked inside. This causes the light bulb to short out and the GFCI and/or circuit breaker to trip. For a tight seal, we recommend replacing the light fixture gasket when you change your light. Old gaskets can become dirty, brittle and develop small cracks which can cause water to seep into the fixture and short out the bulb.
Turn OFF the power to the light and remove the light fixture from the pool. Open the fixture and inspect the inside for signs of water. If you find water in the fixture, dry it out and dry off the light. With the fixture on the pool’s surface, screw in the light bulb and turn the power back on. Be sure to reset the GFCI and/or circuit breaker if it tripped. If the light works properly, seal your fixture and reinstall it underwater.
If the light still does not turn on there may be an issue with the fixture itself. Turn the power to the light off and with the pool’s fixture on the surface, Screw a standard household 110V bulb (any wattage over 40W is fine) into the fixture, turn the power back on. The bulb should light to normal brightness without flickering. If the bulb does not illuminate properly you will need to contact an electrician to determine why the fixture is not receiving the proper voltage (if any)
If the 110V bulb lights properly then your fixture is sending the proper voltage to operate the pool light and the issue may be with the 120V pool light. You can test the light by following the below instructions.
DO NOT perform this test if you have a 12V light. It will blow out immediately.
TO TEST THE 120V POOL LIGHT:
NOTE: If water was present in the pool fixture be sure to check the light itself. If there is water inside the light, this test should NOT be performed when electricity is involved.
If no water is present inside the light, dry the outside of the light off and screw it into a standard household lamp or socket and turn the light switch on. If the light comes on, use the remote to cycle through and check the color modes. If everything seems to be working properly, install the light into your pool fixture and test it one more time on the pool surface before sealing your fixture and installing it underwater. If the light does not function properly in a standard household lamp or socket then it will need to be replaced. Please click here to fill out the warranty claim form to receive a replacement light.
