Pentair IntelliBrite® 5G White LED Light Engine Replacement Kit (300W) | 619875Z

The Pentair 619875Z is a replacement LED light engine / circuit board assembly (PCBA) for select IntelliBrite® 5G White underwater pool and spa lights. It’s designed to restore bright white illumination when the original LED engine fails (no light, intermittent operation, flickering, or dim output), while keeping your existing light housing, lens, and cord in place (when those components are still in good condition).

Key Features

  • 300W IntelliBrite 5G White LED engine replacement (model-specific).
  • Field-replaceable PCBA that renews the light’s internal LED/driver assembly.
  • Includes thermal transfer strips (used to help move heat away from the board inside the fixture).
  • OEM-fit for compatible IntelliBrite 5G White fixtures where 619875Z is specified.

Compatibility

  • Fits: Pentair IntelliBrite 5G White underwater pool/spa light fixtures that use the 300W engine (confirm by your light model/parts diagram).
  • Not for: IntelliBrite 5G Color lights (they use a different engine/board).
  • Tip: If you’re unsure whether your light is the 300W version, match the part number on your diagram or the existing internal board.

What’s Included

  • (1) IntelliBrite 5G White LED engine / PCBA assembly
  • (2) Thermal strips (for proper heat transfer during reassembly)

Common Reasons to Replace

  • Light will not turn on (after confirming power, GFCI, and switch/controller are functioning)
  • Intermittent operation, flickering, or unstable output
  • Dim/uneven illumination compared to normal performance
  • Water intrusion damage inside the fixture (after correcting the sealing issue and replacing the gasket)

Installation Notes

  • Safety first: Turn off power at the breaker and verify the circuit is de-energized before servicing.
  • Remove the light from the niche and place it on the deck (do not attempt to service by splicing or working on wiring underwater).
  • Replace the lens gasket any time you open the light—reusing old gaskets is a common cause of leaks.
  • Install the new board and apply the thermal strips as required for proper heat transfer.
  • Reassemble evenly and test operation before returning the fixture to the niche.
  • If the fixture shows corrosion, cracked lens, warped face ring, or compromised sealing surfaces, replace those components as needed.

Maintenance Tips

  • Keep water chemistry balanced to reduce corrosion and extend the life of lighting components.
  • If you ever open the light, replace the gasket and clean the sealing surfaces before reassembly.
  • When troubleshooting, confirm GFCI, switch/controller, and junction box connections before replacing internal parts.
  • If moisture or fogging appears behind the lens after service, shut off power and correct the seal immediately.
