Built to last, built to install fastThe LUNA 3.5" starts with a durable
airtight fixed aluminum body — the kind of construction that keeps conditioned air where it belongs instead of leaking into the attic. An anodized blue heat sink is integrated to maximize airflow around the LED light source, which is what protects colour consistency and lumen output over the years. Two spring-loaded clips hold the fixture in place in virtually any ceiling material, from drywall to plywood to acoustic tile, so a
retrofit pot light installation comes down to a clean hole and a firm push. At 4 3/8" (111 mm) in diameter with a 3 3/8" (85 mm) body height, it slips into tight joist bays where a 4" or 6" housing simply won't go.
Light quality you can seeThe 12 watt LED module maintains uniform intensity and produces up to
600 lumens with a typical
CRI of 90. That high colour rendering is the difference between a countertop that looks grey and one that looks like real stone. The fixed
3000 K colour temperature is the classic warm-white living tone Canadians reach for in kitchens, living rooms and bedrooms, and the lens shapes a
38° beam spread — tight enough to layer pools of light down a hallway or over an island, wide enough for general ambient coverage. LM79 and LM80 testing are both on file, and projected life is 70% of initial output at 33,000 hours.
Electrical and dimmingPower comes from a
300 mA dimmable Class II electronic LED driver housed in an extruded aluminum hardwire box, with an input of
100-135V AC, 50/60 Hz and a power factor above 0.90. Three "quick connect" push-in terminals make wiring fast on a long install day, 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. Dimming is
TRIAC/ELV, so it pairs with industry-standard wall dimmers; LITELINE publishes a compatible dimmer list for the LUNA family, and the fixture also accepts the LC-CRTL-DIM-1 smart Wi-Fi dimmer, 120V, as a listed accessory.

Accessories, compatibility and documentationAccessories are sold separately and open up every install scenario: the P-3520 3 5/8" round pre-mounting plate and the P-3520NC new construction plate, both with driver attachment clip for 3½" LUNA fixtures; the P-NCMK-1 new construction mounting kit with hanger bars, brackets and screws; the VBE-1 vapour barrier extender for new construction and the VBE-2, VBE-3 and VBE-4 extenders for remodel work — a real answer to the
recessed lighting vapour barrier question in Canadian exterior ceilings. Reducer rings RA35-XLRING-BK, RA35-XLRING-BN and RA35-XLRING-WH cover oversized holes. For a mixed layout, match this black trim with the
3.5" Luna LED round recessed fixture RA35-12F-27K-90BN, step up in temperature with the
3.5" Luna LED round recessed fixture RA35-12F-35K-90BN, or choose the
dim-to-warm version, the
3.5" Luna LED round recessed fixture RA35-12F-DTW-90BK. The full technical PDF spec sheet is in the Documentation tab for your electrician, inspector or lighting plan.
