Built to last, built to install fastThe LUNA 3.5" uses a durable airtight fixed aluminum body with an anodized blue heat sink that maximizes airflow around the LED light source — the detail that keeps light output stable year after year in an enclosed, insulated ceiling. Mounting is handled by two spring-loaded clips that attach to virtually any ceiling material, so drywall, plaster and thin panels are all fair game. The
recessed LED downlight measures 4 3⁄8" (111 mm) and 3 3⁄8" (85 mm) across the trim and body, with a 15⁄16" (34 mm) profile detail, and requires a Ø 3 5⁄8" (92 mm) hole cut — an easy template to repeat across a long hallway or an open kitchen.
Light quality you can seeA 12 watt LED module maintains uniform intensity and produces up to 600 lumens with a typical CRI of 90, so colours stay honest under the beam: countertop veining, cabinet finishes, artwork and merchandise all read correctly. The lens delivers a controlled 38° beam spread, ideal for spacing downlights evenly without hot spots or harsh glare, and the fixture is offered in a 3000 K colour temperature for a clean, comfortable white. Efficiency lands at 57 lumens per watt with a power factor greater than 0.90, and performance is documented through LM79 and LM80 testing.
Electrical, dimming and installationPower comes from an extruded aluminum hardwire box housing a 300 mA dimmable class II electronic LED driver with 100-135V AC input. An 18" (457 mm) FT6 rated cable with a DC 2.1 connector links the driver to the fixture and is approved for use in plenums and suspended ceilings — handy for commercial ceilings and condo bulkheads. Three quick connect push-in terminals make wiring quick and tidy. The fixture is
dimmable with TRIAC/ELV dimmers; check the manufacturer's compatible dimmer list before pairing controls. It is suitable for wet locations, approved for direct contact with insulation, and operates from -20°C to 40°C (-4°F to 104°F).
