Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Cracked or broken lens flange allowing water intrusion
  • Frosted lens is yellowed, cloudy, or discolored
  • Light flickering due to moisture reaching LED assembly
  • Visible physical damage to lens housing
  • Light output is uneven or dim due to lens degradation

Before you buy — quick checklist

  • Confirm your existing lens flange part number is 400372-WF before ordering
  • Verify this is the wide flange (WF) version — measure the outer flange diameter of your current part to confirm it matches
  • Check that your spa uses a Sloan bullet-style light fixture, not a standard flat lens
  • Inspect the LED assembly behind the lens — if the LED board is also damaged, it may need to be replaced separately
  • Confirm the lens material (frosted polycarbonate) is compatible with your spa's sanitizer chemistry, especially if using high ozone or non-standard treatments

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