Pool light replacement is one of the most straightforward upgrade opportunities in residential pool service. The conversion from halogen or incandescent to LED is quick (typically under an hour), delivers a dramatic improvement in light quality and color capability, and generates a $200–600 service ticket with a part that has a 30,000-hour lifespan. Understanding the options, safety requirements, and compatibility considerations makes this a confident upsell.
Most in-wall pool lights use a niche — a watertight housing embedded in the pool wall during construction. The light assembly (lens, housing, bulb or LED array) sits inside the niche and is secured with a single stainless steel screw at the top. A conduit runs from the niche through the pool wall and up to the junction box at the equipment pad.
The key feature for service: there's typically enough cord coiled inside the niche to pull the light fixture out of the niche, over the edge of the pool wall, and onto the pool deck — while the niche itself remains submerged. This means most light services can be done without draining the pool.
A direct LED bulb replacement uses the same base and fits the existing housing. It's the lowest-cost option and the simplest installation. Examples: Pentair IntelliBrite bulb, Hayward NightStar LED bulb, Jandy LED replacement bulbs. The limitation: drop-in bulbs are limited by the existing fixture's optical design, and most don't support color-changing features or automation system integration.
A conversion kit replaces the entire light assembly inside the niche — new housing, new lens, new LED array and driver board. The niche itself stays in place. This is the recommended option for most upgrades because it provides:
Required only when the niche itself is damaged — cracked housing, corroded fitting, or a niche that's incompatible with available LED conversion kits. Niche replacement requires draining the pool and cutting into the pool wall — a significant job that's more renovation than service.

Pool electrical work must comply with NEC 680 (National Electrical Code, Article 680 — Swimming Pools and Fountains). Key requirements: all pool lights within 5 feet of water must be GFCI-protected, 12V systems must use listed transformers, and all underwater luminaires must be listed for the specific voltage and application. Never bypass GFCI protection for a pool light. A pool light failure in a GFCI-unprotected circuit is a fatal electrocution hazard.
Practical safety checklist for pool light service:
Always replace the gasket when servicing a pool light, even if the existing gasket looks intact. A failing gasket allows water into the fixture housing, which causes shorts, bulb failures, and in older halogen fixtures, thermal cracking of the lens from the temperature differential. Gaskets are cheap; repeat service calls because of a saved gasket are not.
Log light model, installation date, and GFCI status in SplashLens. Pool light records are useful for future service scheduling and for demonstrating to homeowners that their electrical safety requirements are being met.
Log light model, installation date, color settings, and GFCI verification per account. Know which lights are aging incandescents ready for LED upgrade — and have the upsell conversation proactively rather than at failure.

The fixture pulls out of the niche on a tethered cord and can be brought to the deck for bulb or conversion kit replacement while the niche remains submerged. This works as long as there's enough cord to reach the deck.
An LED bulb drops into the existing fixture housing. An LED conversion kit replaces the entire light assembly inside the niche. Conversion kits provide better optics, more color options, and are compatible with color-sync automation systems like Hayward ColorLogic or Pentair IntelliBrite.
LED pool lights run at much lower wattage and generate significantly less heat, reducing the risk of fixture overheating. Both types must be GFCI-protected. LED fixtures also have far longer lifespans, reducing the frequency of service events that carry inherent electrical risk.
Quality LED pool light assemblies (Pentair IntelliBrite, Hayward ColorLogic, Jandy WaterColors) are rated for 30,000–50,000 operating hours — roughly 15–25 years at 8 hours per night. The LED elements rarely fail; the more common failure point is the LED driver board or gasket seal.
