The RAB Design RDL4-LED10 is a 4" edge-lit LED recessed downlight built for professional electricians and contractors tackling new construction and renovation projects in residential and commercial spaces. Delivering 645 lumens at just 10.2W, this slim-profile pot light installs quickly with external mounting tabs and a 26.5" cable — no separate junction box fishing required. The on-driver 5-position CCT selector lets you dial in the right colour temperature on the job site without returning to the supply house, while TRIAC dimming (10–100%) ensures compatibility with standard dimmer circuits already roughed in. IC-rated for direct insulation contact, it meets the demands of energy-efficient builds and retrofit upgrades alike.
