An LED recessed retrofit is a fixture that attaches to your current standard housing, replacing both the old light bulb and the trim. To install, you just need to attach the fixture's base adapter to the existing socket, and secure the light in place with built-in clips.

Light fixtures that are recessed in the ceiling to illuminate down onto a space are often called "recessed lights." Recessed lighting LED conversion kits can be installed into existing recessed fixtures by removing the original bulb and trim before screwing in an LED module adapter into place.
