Island Spas Light Parts

Island Spas lighting uses two housing sizes — 2 inch and 3.5 inch — so measure your lens face first, then match bulb, lens, or housing.

Island Spas Light Parts — Measure the Lens, Match the System

Island Spas light parts break down into three layers: the LED bulb inside, the lens you see in the shell, and the housing with gasket behind it. The 2 inch and 3.5 inch systems don’t interchange, so start by measuring across your lens face. A dark light is usually just the bulb; a leak at a light is the housing gasket — and a gasket-stage fix is far cheaper than the shell-side water damage of ignoring it.

Island Spas Light Parts FAQs

Measure across the lens face in the shell: about 2 inches or about 3.5 inches tells you which system you have. Bulbs, lenses, housings, and gaskets are listed by size above. A photo with a tape measure through the form confirms it.

Usually the LED bulb. If a new bulb doesn’t light, the problem moves up the line to the light’s power feed or controller — send us your symptoms and serial number and we’ll point you to the next check before you buy more parts.

That’s the housing gasket (or a cracked housing). Replace it promptly: a weeping light housing is a slow leak into the cabinet. Housing-with-gasket listings above cover both sizes.

✅ Not Sure Which Light Part Fits? Verify Before Ordering

Island Spas part compatibility can vary by model, year, serial number, and part revision.

To help us identify the correct replacement, please send clear photos of:

  • The light lens in the shell, next to a tape measure
  • The housing behind the shell, if accessible
  • Your spa serial number sticker

EZ Hot Tub Parts can confirm fitment before you order and help you avoid costly returns.
