This is a complete OEM fixture including glass lens that has been converted to our upgraded RETROFIT-18-5630 LED Module. You choose Cool White 6000k, Natural White 4500k, or Warm White 3200k.
This fixture is designed to be flush mounted into the ceiling and is held in place with the spring clips. The ceiling hole should be between 3 1/2" to 4" maximum size.
If you have this type of fixture and just need to convert it to a better LED, look at our RETROFIT-18-5630 module alone.
