VOLTAGE 12V vs 120V - Pool lights are designed to operate with 12V or 120V.
12v vs 120v pool light. 120V just doesnt hold up like 12V does. We currently have a Pentair 120 volt light that is burned out. Secondly advancements in LED technology have revolutionized pool and spa lighting with 12V lights now as bright or brighter than their 120V counterparts.
Before installing a light find out what your local code require. The 12V is also safe if the appropriate transformers are used. 12v is more energy efficient costing less in running costs.
Also asked are 120v pool lights safe. Longevity is another big issue. The difference is that 12v lights require a transformer sold separately.
In some areas of the country the local code requires a low voltage 12V light while in other areas it is fine to use a 120V light. One thing about the newer LED fixtures is that if something goes wrong you can not just change a bulb. VOLTAGE 12V vs 120V - Pool lights are designed to operate with 12V or 120V.
I want to replace the bulb with a Color Splash LED which is a replacement bulb with an Edison base. 12v light bulbs generally last longer than 120v due to the heat generated during operation. In some areas of the country the local code requires a low voltage 12V light while in other areas it is fine to use a 120V light.
VOLTAGE 12V vs 120V - Pool lights are designed to operate with 12V or 120V. The brightness of a 12V and 120V will be the same. They typically use 20 to 40 percent less electricity.
