Underwater Pool Lights Buying Guide

Pools are a central component of many homes. The majority of pools feature underwater lighting in order to enhance the swimming experience. Homeowners who need to replace their underwater pool lights must consider a number of factors before purchasing new lights.

Choosing the Right Underwater Pool Lights

Choosing the right underwater pool lights to replace broken or burnt-out lights is essential. Most pool owners choose lights both for their utilitarian value and for the aesthetic appeal that they can add to a pool. When choosing pool lights, it is important to keep a number of factors in mind.

First and foremost, buyers must decide what types of lights they will buy according to the fittings found in their pools. Most modern pools will accept either 12- or 120-volt traditional and LED lights. In order to determine the type of lights needed, pool owners should check their owner's manuals. Specifications can also be found on burnt-out bulbs. The majority of light fixtures are designed with a coil mechanism so that they can easily be brought to the surface of the pool for maintenance and repairs.

Buyers who are shopping for pools made before 1968 may need to search for specialty lights. Electrical standards for pools were not in place prior to 1968. Homeowners who are shopping for pools made prior to this time period may wish to buy new caging and wiring supplies so that pool lights can be replaced and updated. Remember that it is usually necessary to have a professional technician replace pool lights.

In general, pool lights consume very little energy. The average 12-volt underwater pool light will run for more than 1,000 hours before it must be replaced. Homeowners who wish to cut down on electricity usage and extend pool light life should consider placing their pool lights on a pool light timer.. Such timers can also control filters, pumps, and other essential pool functions.

The Advantages of Underwater LED Pool Lights

The majority of pool owners prefer to purchase LED pool lights.. LED lights have a much longer lifespan than traditional 12-volt bulbs. They also tend to burn brighter than traditional bulbs. Like their traditional counterparts, LED lights are rated at 12 or 120 volts.

LED pool lights are available in a wide variety of colors. For many homeowners, this is one of the primary attractions of LED lights. In the past, pool lights were often tinted with special filters in order to create color effects. Today's LED lights do not use such filters. They produce pure, strong color.

Many LED pool lights are classified as color-changing pool lights.. These lights are particularly ideal for homeowners who enjoy entertaining poolside. Almost all color-changing lights can be programmed to change colors according to a variety of different rhythms and patterns.

Buyers should be sure to differentiate between LED lights designed to be installed in underwater fixtures and those lights designed to float on the surface of the pool. While surface LED lights can add a touch of glamour to any pool, they will not fit into light housings. Be sure to buy LED lights that are specifically rated for underwater use.

Many buyers also prefer LED lights because they do not suffer from the heat problems of traditional 12-volt lights. In general, traditional 12-volt lights cannot be run above water for more than a few seconds due to overheating issues. LED lights have no such issues. Buyers can easily check LED lights to ensure that they are properly installed in light caging without submerging the lights in the pool.

Choosing the Right Light Caging Materials

In general, underwater pool lights are protected by either a plastic or stainless steel cage. This cage features a rubber gasket, which prevents excess water from entering electrical fixtures. Many LED lights are sold with a cover already installed to cut down on leakage problems.

Buyers who wish to choose sturdy, long-lasting light caging are advised to look for underwater pool lights that feature stainless steel caging. While many plastics are durable, they will not outlast stainless steel. Buyers should keep in mind that stainless steel cages will cost considerably more than plastic cages.

How to Buy Underwater Pool Lights

Individuals who wish to buy underwater pool lights will be able to find such lights both at online retailers and in brick-and-mortar pool supply stores. Some general discount stores may also carry pool lights. Shoppers will find the largest selection of pool lights at online retailers.

Choosing 12-Volt or 120-Volt Underwater Pool Lights

The majority of buyers will be shopping for 12-volt pool lights.. Lights that are rated at 120 volts are generally used only in large pools or pools with dated electrical systems. Remember that both traditional and LED lights are available in 12- and 120-volt versions.

When shopping for 12-volt pool lights, it is essential that pool owners check light fittings to see if they accept a bulb with a small, medium, or large base. Both traditional and LED lights will be rated according to the size of their base. It is important to remember that bulbs of different bases are not interchangeable. Substantial electrical changes must be made to a pool in order to change the size of bulb that light fittings can accept.

Changing Underwater Pool Lights

Most homeowners will be able to replace underwater pool lights without the help of professionals. Be sure to carefully follow the steps listed below when changing underwater pool lights.

Before attempting to remove light fixtures, switch off the electricity to the pool. This should be done at the breaker level. After the electricity has been switched off, remove the top screw from the underwater light caging. Next, the light will need to be pried out of the niche. Almost all lights can be pried out by using a flat-head screwdriver. Many lights have a notch designed for this purpose along the bottom edge of the caging.

Bring the lighting fixture to the surface of the water and place it on the pool's edge, also called the coping stone. Carefully remove all clamps and screws holding the light's caging to its glass or plastic cover. After the clamps and screws have been removed, lift off the glass or plastic cover. Remember that many LED lights are designed to be installed without this glass cover.

After the light's cover has been removed, cover the bulb with a soft cloth and twist it counterclockwise to remove it from the light caging. Some halogen lamps will need to be slightly depressed in order to be removed. Remember to use caution as old bulbs can become brittle and may break easily.

After the light bulb is removed, wipe any moisture out of the light's caging with a soft, clean cloth. Confirm that the bulb's base is the correct size before screwing the new bulb into the light fixture. After the bulb has been screwed into the light fixture, turn on the power briefly to ensure that the bulb works. Remember that traditional lights cannot be run for more than a few seconds outside of the water.

Replace the bulb's cover and caging. It is essential that homeowners always use a new light gasket when replacing an underwater bulb. This prevents water from entering the light caging and causing corrosion. Submerge the light in the pool after the gasket and caging have been replaced. If bubbles appear, the gasket has not been installed properly.

Return the light caging to the underwater niche. Press it into place and then carefully screw the caging back into the niche. After all burnt-out lights have been replaced, turn the power to the pool on at the breaker level.

Underwater Pool Light Pricing

Buyers who are purchasing underwater pool lights for the first time will notice that underwater bulbs can be quite expensive. LED lights are generally less expensive than traditional electric bulbs. Remember to carefully read the description of LED lights to ensure that they are designed for underwater use. Many of the LED lights on today's market are designed to float at the top of the pool but are not suited to installation in underwater fixtures.

Underwater Lighting Fixture and Gasket Pricing

Underwater lighting components and gaskets tend to cost less than traditional underwater light bulbs. Remember that new gaskets should always be applied when changing underwater lights. More extensive electrical repairs generally require the assistance of a trained professional.
