Pool Light Replacement & LED Pool Lighting in Phoenix, AZ
Burned-out pool light? Casther Electric replaces incandescent and first-generation LED pool lights with current color-changing LED fixtures across Greater Phoenix. Licensed AZ ROC #311594. Typical cost: $400–$800 per light, including the niche inspection and GFCI test.
When a Pool Light Should Be Replaced
A pool light that flickers, won’t turn on, fills with water, or trips the GFCI is telling you something. The most common failures we see in Phoenix pools are corroded sockets from hard water, cracked lenses from age and sun, and old incandescent fixtures that draw too much current. If your light is more than 8–10 years old, replacing it with LED usually pays for itself in energy savings within two seasons.

Frequently Asked Questions
How much does pool light replacement cost in Phoenix?
Most single-light LED replacements run $400 to $800 in the Phoenix area, including the niche inspection and GFCI test. The exact price depends on the fixture brand and whether the existing conduit and niche are in good condition.
Can you replace an incandescent pool light with LED?
Yes. Swapping an old incandescent fixture for an LED is one of our most common jobs. LED pool lights use roughly 75% less energy and last far longer, so the upgrade usually pays for itself within two pool seasons.
Why does my pool light keep tripping the GFCI?
A pool light that trips the GFCI usually has water in the fixture, a failing socket, or a wiring fault in the niche. This is a safety issue around water and should be inspected by a licensed electrician right away. We diagnose the root cause rather than just resetting the breaker.
Do you need to drain the pool to replace a light?
No. In almost all cases we replace the light without draining the pool. The fixture is pulled up to the deck on its excess cord, replaced, sealed, and returned to the niche underwater.
