Frequently Asked Questions

What part number is this pool light?

This item is supplied under part number 78456300. Match that number against your equipment's parts diagram before ordering.

Can I put an LED light in my existing niche?

Most LED replacements are designed to drop into standard niches, but you must match the voltage, the niche size and the cord length. A 12V fixture cannot run on a 120V circuit without the correct transformer.

What cord length do I need?

The cord must reach from the niche to the junction box without a splice, which is a code requirement in most areas. Measure the run and add slack for the service loop that lets you lift the fixture onto the deck.

Do I need to drain the pool to change the light?

Usually not. Most fixtures have enough cord to be lifted onto the deck with the pool full, though the power must be switched off at the breaker first.

How do I confirm this part fits my equipment?

Check the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.

How quickly does this ship?

In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.

Can I return it if I ordered the wrong part?

Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.

Is this covered by a warranty?

Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
