Pool and Spa Lights

The easiest way is to match what you already have: (1) voltage (commonly 12V or 120V), (2) light type (LED vs halogen/incandescent), (3) fixture style (niche/wet-niche fixture vs bulb-only vs retrofit), and (4) cord length. If you can find your current light’s model number on the fixture or lens ring, that’s the fastest path to a perfect match.

LED pool lights use far less electricity, usually run cooler, and often last longer—plus many models offer color-changing modes. Halogen/incandescent lights are typically lower upfront cost but use more power and create more heat. If you want the most efficient upgrade, LED is usually the go-to choice.

Voltage matters because the replacement must match your electrical setup. Many pool lights are 12V (low voltage) and use a transformer; others are 120V (line voltage). Check the label on the fixture, the transformer (if present), or the existing light documentation before ordering.

Sometimes. If your existing housing and lens are in good shape and the light is designed for bulb replacement, a bulb can be a cost-effective fix. If the fixture is corroded, leaking, or you want an LED/color upgrade, replacing the entire light (or using a retrofit kit designed for your niche/fixture) is often the better long-term move.

A niche is the built-in housing in the pool wall that the light fixture mounts into. Not all lights fit all niches. For the smoothest replacement, choose a light that’s listed as compatible with your niche/fixture type (often tied to the original manufacturer and series).

Cord length needs to reach from the light niche to your junction box/transformer with enough slack to pull the fixture onto the deck for future service. If you’re replacing an existing light, matching (or slightly exceeding) your current cord length is usually the safest choice.

Many color LED lights change colors by toggling power in specific on/off sequences at the wall switch. If you use pool automation, confirm the light is compatible with your controller (or the manufacturer’s recommended control method) so colors and shows work as expected.

Spa lights are often smaller and may use different niches/fixtures than full-size pool lights. When shopping, match whether it’s a pool or spa light first, then confirm voltage, fixture/niche style, and cord length.

Water in the fixture usually points to a sealing issue (often a lens gasket) or a compromised housing. If the fixture is otherwise solid, a new gasket may solve it. If there’s corrosion, repeated leaks, or you want an upgrade, replacing the fixture is often the better option.

Yes. If you can share the light’s model number (or clear photos of the lens ring/fixture label), plus your voltage and cord length, we can help you pick a compatible replacement or retrofit option. Visit our Support page to contact a pool expert.
