About this lighting

The Sloan Large Faceted Bullet Light Lens 400372-WF-LRG is a premium replacement lens designed for Sloan spa lighting systems. This wide-flange frosted polycarbonate lens delivers even light diffusion while maintaining the durability needed for demanding spa environments.

Engineered with UV-stable materials, this large faceted lens resists yellowing and cracking from prolonged exposure to chemicals and sunlight. The frosted finish creates attractive ambient lighting while the wide flange design ensures secure mounting. At Bubbles Supply, we guarantee this OEM-quality lens provides an exact fit for your Sloan lighting fixture, backed by our 1-year warranty and same-day shipping on in-stock orders. Verify your existing lens size and flange configuration before ordering to ensure proper fitment with your spa's lighting assembly.

Common symptoms this part fixes

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

  • Cracked or shattered lens allowing water intrusion
  • Yellowed or discolored lens reducing light output
  • Lens fogged beyond cleaning due to UV degradation
  • Chemical etching causing cloudy or dull light diffusion
  • Missing lens leaving fixture exposed to spa water

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing lens is the large size — Sloan bullet lenses come in multiple sizes and the flange diameter must match your fixture housing
  • Verify the wide-flange (WF) configuration matches your current mounting ring — standard flange and wide flange are not interchangeable
  • Inspect the fixture body itself before ordering a lens — if the housing is cracked or the socket is corroded, a lens swap alone won't fix the problem
  • Check that your existing lens has a faceted (multi-cut) face profile, not a smooth dome — these are visually distinct and not cross-compatible
  • Note your current lens part number or measure outer diameter before ordering if you are unsure of size

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