Installation Instructions
Note: No ceiling can or housing is required for this trimless downlight. Always ensure power is disconnected before installation.
- Prepare the Cutout: Create a suitable opening in the ceiling for the plaster frame. Refer to the product dimensions for accurate sizing.
- Install the Plaster Frame: Insert the plaster frame into the new cutout. Secure the plaster frame to the sheetrock using appropriate screws. This frame will be plastered and painted over to achieve a seamless, trimless look.

- Plaster and Paint: Once the plaster frame is securely installed, plaster and paint over it to blend it with the ceiling surface. Allow sufficient drying time.
- Connect the Junction Box: Feed the integrated junction box through the plaster frame opening. Make the necessary electrical connections inside the J-Box according to local electrical codes. Ensure the J-Box is accessible for future servicing if required.
- Install the Downlight Fixture: Connect the downlight fixture to the junction box cable. Carefully insert the downlight fixture into the plaster frame opening. Twist and lock the fixture into place using the integrated twist locks. This secures the light and completes the trimless installation.
