Lutron Lumaris RadioRA 3 4 in Retrofit Tunable White Downlight – 1800K–4000K, White or Black Trim | RRL-RD4WH-TW / RRL-RD4BL-TW

The Lumaris 4 in retrofit downlight upgrades existing 4 in recessed cans to tunable white and warm dim under RadioRA 3 control. With a 3 in aperture sized for 4 in housings, it installs quickly into pre-existing cans without special tools, modifications, or pulling control wire.

System Notes

• Retrofit form factor for pre-existing cans — for new openings, specify the Lumaris canless downlight (RRL-CD series) instead
• Choose trim color as the variant: White (RRL-RD4WH-TW) or Black (RRL-RD4BL-TW); 4 in and 6 in class fixtures are listed separately
• RRL- model numbers are the RadioRA 3 versions — do not substitute HomeWorks QSX (HWL-) model numbers
• Controlled natively over Lutron Clear Connect – Type X wireless; no low-voltage control wiring required
• Power the fixture from constant (unswitched/undimmed) 120 V — do not wire through a phase-control dimmer
• Verify layout, load, and control requirements before ordering
