Frequently asked questions
Can I replace an incandescent pool light with an LED?
In most cases yes, and it is the common upgrade path, but the niche size, cord length and voltage must all match. LED fixtures draw far less power and last considerably longer than the incandescent lamps they replace.
What is the part number for this pool light?
Pentair lists this pool light under part number 78456300. Quote 78456300 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How long a cord do I need?
The cord has to reach from the niche all the way to the junction box with slack for servicing - installers normally leave enough to lift the fixture onto the deck. Cord length is fixed at the factory, so measure before ordering rather than after.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Does pool light work need an electrician?
Pool lighting sits under specific electrical code requirements covering bonding, grounding and GFCI protection. Cut power at the breaker before removing any fixture, and have a licensed professional handle the junction box and supply side.
Is there a warranty on this pool light?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
