Before you buy — quick checklist

  • Confirm the part number ACM0749 is printed on your existing light or original documentation before ordering
  • Verify your spa's control system is compatible with RGB LED lighting — some older Wellis controllers may not support full color cycling
  • Inspect the existing wiring harness and connector for corrosion or damage before installation
  • Check that the mounting recess or fixture opening in your spa shell matches the dimensions of this unit
  • Confirm whether your current light failed due to a wiring or control board issue — replacing the light alone will not fix upstream electrical faults

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