About this lighting

This genuine OEM light lens is designed specifically for Hot Spring Spas Limelight series spas manufactured from 2018 to current model years. The low-profile design features a 1.75" diameter that maintains the sleek aesthetic of your spa while providing reliable underwater illumination protection.

Engineered to Hot Spring's exact specifications, this replacement lens ensures a perfect seal and optimal light transmission. At Bubbles Supply, we guarantee an exact fit with same-day shipping on in-stock items, backed by our comprehensive 1-year warranty. The durable construction withstands constant exposure to spa chemicals and temperature fluctuations. For proper installation, ensure the spa is powered off and allow the light fixture to cool completely before replacing the lens to prevent thermal shock and ensure a secure seal.

Before you buy — quick checklist

  • Confirm your spa is a Hot Spring Limelight Series manufactured 2018 or later
  • Measure the existing lens diameter to verify it is 1.75"
  • Inspect the light fixture body for damage — a cracked housing will need separate repair before installing a new lens
  • Check whether the existing lens is sealed with an o-ring or gasket and source a replacement seal if needed
  • Verify the lens retainer ring or mounting hardware is intact before ordering only the lens

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
