Swimming pool lights are important safety features that increase a swimmer’s visibility at night and help observers to locate swimmers. Locating swimmers during an emergency, such as drowning, is imperative and pool lights can potentially be lifesaving. While pool lights are beneficial from a safety standpoint, they also improve the aesthetics of a pool, particularly at night. Pool lights can come in a variety of colors, and some have color-changing modes.
A swimming pool light submerged in pool water may seem challenging to change; however, it is typically a straightforward process that can be done with nothing more than a pair of screw drivers. The homeowner may not even need to lower the water level of the pool.
To begin the process, switch off the circuit breaker associated with the light. Next, test the light to ensure it does not come on.
Most pool light fixtures are attached to the pool using a single Phillips-head screw. Sturdy yourself on the edge of the pool (laying on your stomach is a good option). Reach into the pool with a Phillips screwdriver and unscrew the top screw or “screwlock”. The light fixture may come out on its own or you may need to pry it off the pool using a flat-head screwdriver. If the light is in serviceable condition, it should come off easily.
Next, pull the light fixture up out of the water and set it on the pool deck. The light fixture should be attached to a long water-proof electrical cord. The cover, lens, and gasket for the fixture may be screwed on, or they may have mounting tabs that need to be pulled back. The light bulb can then be taken out and replaced, just like a light bulb in your home.
Finally, reverse the steps taken when removing the light fixture. It is a good idea to submerge the light fixture for a few seconds prior to mounting it against the pool to make sure there are no air bubbles coming out through the gasket. This will ensure a proper seal. The electrical cord may need to be wrapped around the back side of the fixture upon re-mounting to ensure it fits flush against the pool vessel. Make sure that the mounting screw is made of stainless steel to help prevent rusting. Once the light has been properly secured turn the breaker back on and test the light.
LED light bulbs are the best option for swimming pool lights as they last longer than incandescent, CFL, and halogen lights. LED bulbs also use less energy and come in a variety of colors.
While replacing a swimming pool light is a task that the homeowner can usually complete, there are specific instances when this is not the case. For example, a pool located on a hill with its electrical equipment located below the pool may need to be drained before you change the bulb. If you are unsure about the safety protocols for changing your pool light, you should reach out to a qualified pool company for further evaluation.
