Changing the pool’s light bulb is as easy as changing the light bulb in your home and as long as you don’t become complacent with electrical power to the pool and light then it could save a bunch of money. Follow these directions. 

How to Replace Pool Light

 

Disconnect Electricity to the Pool

-Turn the pool light on

-Shut the main circuit breaker off to the swimming pool light.

I turned the power off to the whole swimming pool filter system just for safety.  If you don’t know where the main breaker is stop. Call an electrician. If you do continue on.

Use a voltage tester against the swimming pool light wall switch. Turn the switch to the “On” position and double-check the switch and power are dead. Return the switch to the “Off” position. 

-Remove Screw Holding Light Housing

Look for the single screw along the bottom of the pool light housing bezel. Enter the pool to access the screw if you cannot reach the screw from outside the pool. Remove the screws from the housing.

-Remove the Light Housing

The light should pull out the housing from the side of the pool. The housing has a long around 6ft, waterproof cord attached to it, so you can replace the light from outside the pool. Place the light housing on a towel outside the pool.

-Loosen Other Screws

Look behind the bezel for a single brass screw or a series of brass screws holding the bezel, light housing gasket, and lens to the housing. Loosen the screws to release the bezel, gasket, and lens from the housing.

-Remove the Original Bulb

Dry the inside of the housing with a soft towel to remove any moisture. Grab the original bulb with the towel and untwist it to the left from the housing socket then lay it to the side.

-Install the Replacement Bulb

Swap with the new replacement bulb (must match the size, shape, and watts of your original bulb) but If the bulb is a standard 500-watt incandescent bulb swap it with a  comparable LED low-voltage pool light.

Screw the replacement pool light bulb in the light housing. Install a new light housing gasket around the edge of the light lens if applicable. Position the lens on the end of the housing and install the bezel over the lens.

-Replace Pool Light Housing

Tighten the screw or screws holding the bezel to the pool light bulb housing. Wind the housing waterproof cord around the housing.

Insert the pool light housing into the pool light opening in the pool wall. If a steady stream of air bubbles escapes from the housing after you submerge it in the water, you must remove and replace the bezel, gasket, and lens to ensure you properly seal the pool light against water seepage.

-Secure Light Housing Screw

Secure the light to the pool wall with the screw you removed earlier. Turn on the pool lighting circuit breaker. I always test the GFI Breaker once the light is back in place. 

 

 

LED Pool Lighting

 

The 120v pool lights are fairly common, and safe when installed correctly according to the National Electrical Code, 12v lights are potentially safer and some of them are even considered “intrinsically safe” by the NEC and UL due to their non-conductive material design and low voltage two wire system.

More and more pool owners upgrade to LED light fixtures which can actually outperform 120v lights and provide all the beautiful color options for a pool.

Some 120v pool lighting uses a regular bulb socket called a standard Edison base which allows for the replacement of the existing white bulb with a color-change-capable LED light without changing any electrical equipment or another existing wiring to your pool light bulb like adding a 12v step-down transformer. Simply take the bulb out of the lens and housing, open it, and swap the bulb out with this 120v LED pool light fixture.

 

Pool bulb replacement is a pretty straightforward task just swap out the burned-out bulb from the niche. But something to keep in mind is that your pool bulbs don’t have to be burned out for you to replace them. You can also change a bulb to higher lumens, more energy-efficient LED bulbs that burn a fraction of the energy traditional incandescent pool bulbs do.

Most of the older incandescent and halogen pool bulb light fixtures can be changed to the newer LED color-changing lights by replacing the entire light fixture. However, there are a limited number of old lights that can be converted to LED light by simply replacing the old light fixture bulb with a color-changing LED light bulb.

Most of the older incandescent and halogen pool lights can be changed to the newer LED color-changing lights by replacing the entire light fixture. But there are a limited number of old lights that can be converted to LED pool lighting lights by simply replacing back the old light fixture bulb with a color-changing LED light bulb

On average, a pool light will last around 3-5 years depending on the types of bulbs and their voltage level, the type of light housing, the environment, and the amount of use. Halogen and incandescent bulbs typically last an average of 3-4 years while a LED light bulb will last up to 5-6 years.

You can replace your old pool bulb light fixture with an LED bulb. It is a great way to achieve cost savings and increase efficiency and aesthetics. LED pool lights are extremely low maintenance compared to traditional halogen pool lights, and they provide a much brighter, whiter light with a lens that can enhance the beauty and color of your pool.

Additionally, they consume much less energy than standard fixtures, and the bulb can last up to much longer. When replacing your old pool light with an LED, bulb it is important to ensure that you choose the correct lighting fixture that is compatible with your existing pool equipment. Be sure to consult a professional pool contractor or an electrician to ensure that the right voltage and wattage are used for your specific pool lights.

 

Pool Water Light GFI Bulb Pool Lights

 

The first GFCI light will flash green or red to indicate operating status. The second light will flash amber to indicate a trip or fault in the circuit. When the device is first wired up or in a tripped condition, the green status indicator light and the amber indicator pool light should be on.

Leviton SmartlockPro® Self-Test GFCI devices, introduced in 2015, feature a small LED status indicator light to give you a convenient way to check the level of ground fault protection a glance. GREEN LIGHT indicates the device has passed the self-test and is providing power through the circuit. RED means the device needs attention.

How do you tell if a GFCI breaker is tripped?
Locate your house’s main electrical panel and the circuit you want to test. With the breaker in the ON position and the lamp plugged into that circuit, hit the TEST button. The lamp should turn OFF. The breaker should trip and move to the OFF position or middle “TRIP” if it has one.
If you press the reset button and it won’t stay in, this indicates that you’re dealing with a ground fault somewhere downstream from the GFI outlet. Your GFCI outlet protects receptacles that are downstream from it, and if the outlet is overloaded with a load, this will be a problem.

Before resetting the wet GFCI outlet, check the other outlets on the same circuit. Turn off and unplug any other appliances connected to this circuit. Use a voltmeter to confirm whether the outlets are live or not.

  • Turn off the circuit breaker connected to the wet GFCI outlet. This will prevent any electrical accidents as you deal with the GFCI. 
  • The easiest way to dry out your GFCI electrical outlet is to use a battery-operated hairdryer. Begin with the lowest setting and aim for the moist areas. Don’t put the hair dryer too close to the outlet as the hot air may melt the plastic or the wire insulation. Dry out every outlet that may have been exposed to water. 
  • Turn on the circuit breaker and check GFCI once you’re sure the electrical outlet is dry. If the electricity is on, reset the GFCI unit. If the GFCI resets without a problem, your issue has been fixed, and you can use the outlet again without worry. If the GFCI immediately trips after you try to reset it, there may still be some lingering moisture in the outlet. It is also possible that the outlet has been damaged and needs repair or it must be replaced.

Always Check your Electric wiring and GFI at the filter in the Timer Box. Experts recommend once per month. 

  • Turn on the Pool Light and Push the GFI Test Button-then Reset the circuit
  • Turn on the Pool Pump and Test the GFI Button then Reset the circuit
  • Turn on Both the Pump and the Pool Light along with the receptacle with a load on it. The radio is good. Press the Test Button. If it’s all working Reset The GFI and put the filter back on manually.
  • GFCI Receptacles contain both a reset button and a test button.

When an electrical current problem is detected, the GFCI can manually be reset by simply pushing the red reset button in the middle of the receptacle. Along with the reset button, there is also a test button that can be used to verify that the GFCI works properly.

To test the GFCI, turn on the pool light and simply press the test button. If it is working correctly, you should hear a snap sound that trips the outlet and cuts off the power,  turning off the light or other powered appliances.
