Built to disappear into the ceilingThe LUNA 3.5" round fixed downlight is built around a durable airtight fixed
aluminum body with an anodized blue heat sink that maximizes airflow around the LED light source — the single best predictor of how long an integrated
LED recessed light will hold its output. The fixture measures 4 3/8" (111 mm) across the trim with a 3 3/8" (85 mm) body, a 3 1/16" (78 mm) depth and a 4 3/16" (106 mm) span at the clips, and it drops into a
Ø 3 5/8" (92 mm) hole cut. Two spring loaded clips attach it to any ceiling material, which is what makes it such a fast retrofit in existing drywall, plaster or panelled ceilings. This SKU ships with the brushed nickel (BN) trim finish.
Light quality and dim-to-warm controlThe 12 watt LED module maintains uniform intensity and produces up to 600 lumens with a
typical CRI of 90, so colours, cabinetry and merchandise read true instead of washed out. The lens delivers a
38° beam spread — tight enough to layer nicely over a counter or a hallway, wide enough to light a room when spaced properly. Colour temperature starts at
3000 K and warms to 2000 K as you dim, mimicking the glow of an incandescent as the evening goes on. Dimming is handled by industry-standard
TRIAC/ELV dimmers; Liteline publishes its compatible dimmer list at liteline.com/lunadimmers.

Wiring and installationPower comes from an extruded aluminum hardwire box housing a
300 mA dimmable class II electronic LED driver with 100-135 V AC input. Three "Quick connect" push-in terminals make wiring fast — no wire nuts, no fumbling above your head — and an 18" (457 mm)
FT6 rated cable with a DC 2.1 connector links the driver to the fixture, approved for use in plenums and suspended ceilings. The fixture is suitable for wet locations and approved for direct contact with insulation, so it can go in an insulated attic ceiling, under a soffit or in a shower area without a separate housing. Accessories are sold separately, including the P-3520 round pre-mounting plate and the P-3520NC new construction plate with driver attachment clip for 3½" LUNA LED fixtures, the P-NCMK-1 new construction mounting kit with hanger bars, brackets and screws, the VBE-1 to VBE-4 vapour barrier extenders, the RA35-XLRING-BN brushed nickel reducer ring, the SLM-60-FC flexible connector and the LC-CRTL-DIM-1 smart Wi-Fi dimmer.
Where it works, and what's on the pageThink kitchen downlights over an island, a run of
dimmable LED downlights down a hallway, bathroom and ensuite ceilings, covered entries and porches, basement renos, condo corridors, dental clinics, salons, boutiques and small offices. Because the same 3½" platform is offered in several finishes and colour temperatures, you can keep one aperture size throughout a project and change the mood room by room — see the
RA35-12F-35K-90BN, the
RA35-12F-90BN or the dim-to-warm
RA35-12F-DTW-90BN. The full technical PDF spec sheet is available in the Documentation tab for dimensions, the ordering guide and the accessory list.
