Built to last, built to disappear into the ceilingThe LUNA 3.5"
recessed downlight is built around a durable airtight fixed aluminum body — no plastic housing, no rattles, no air leaks through the ceiling plane. Inside, an anodized blue heat sink keeps air moving around the LED source, which is exactly what protects long-term light output and colour stability. The trim is finished in black (BK), a favourite for contemporary ceilings, dark accent walls and spaces where you want the aperture to read as a quiet dot rather than a bright ring. Two spring-loaded clips are included and grip any ceiling material, so the fixture sits tight to drywall, plaster or panel without fuss.
Dim-to-warm light qualityThis is a
dim-to-warm fixture: colour temperature travels from 3000 K down to 2000 K as you lower the dimmer, so a room that feels crisp and functional at dinner prep becomes candle-soft by the end of the night. The 12 watt LED module maintains uniform intensity and produces up to 600 lumens with a typical CRI of 90, a high-fidelity rendering level that flatters wood, stone, textiles and skin tones. The lens delivers a 38° beam spread — tight enough to create clean pools of light on a counter or island, wide enough to layer comfortably at standard ceiling heights. Dimming is compatible with industry-standard TRIAC/ELV dimmers.

Wiring and installationThe extruded aluminum hardwire box houses a 300 mA dimmable Class II electronic LED driver with 100-135V AC input, and three "Quick connect" push-in terminals make the line, neutral and ground connections in seconds — a real time-saver when you're running a dozen
pot lights down a hallway. An 18" (457 mm) FT6-rated cable with DC 2.1 connector links the driver to the fixture and is approved for use in plenums and suspended ceilings. The fixture is approved for direct contact with insulation and suitable for wet locations, so it can go in a shower ceiling or a covered exterior soffit. Overall fixture dimensions are 4 3/8" (111 mm) and 3 3/8" (85 mm), with a 4 3/16" (106 mm) and 3 1/16" (78 mm) hardwire box and a 15/16" (34 mm) profile — plan a Ø 3 5/8" (92 mm) hole cut.
