Built to last, built to install fastThe LUNA 3.5" round fixed downlight uses a durable
airtight aluminum body with an anodized blue heat sink that keeps airflow moving around the LED source — the single biggest factor in how long an integrated LED fixture actually holds its output. Two spring-loaded clips grip any ceiling material, so the fixture seats flush in drywall, plaster or panel ceilings without extra hardware. The extruded aluminum hardwire box carries three "Quick connect" push-in terminals for fast wiring, and an 18" (457 mm) FT6-rated cable with a DC 2.1 connector links the driver to the fixture — a cable approved for use in plenums and suspended ceilings, which matters on commercial jobs.
Light quality and dim-to-warmThe 12 watt LED module maintains uniform intensity and produces up to 600 lumens with a typical CRI of 90, a level of colour rendering that keeps countertops, cabinetry and merchandise looking rich rather than washed out. As you dim, the
colour temperature travels from 3000 K down to 2000 K, recreating the warm glow people love from incandescent sources — ideal for dining rooms, hospitality spaces and bedrooms. The lens delivers a 38° beam spread, tight enough to keep light where you aim it, wide enough for general ambient coverage when the fixtures are laid out on a regular grid.

Installation, dimming and accessoriesCut a Ø 3 5⁄8" (92 mm) hole, feed the hardwire box into the cavity, connect line, neutral and ground to the push-in terminals, clip the fixture in place — done. The driver is approved for direct contact with insulation, so no keep-away zone is needed in an insulated attic or a sloped ceiling. For dimming, use a standard
TRIAC or ELV dimmer; LITELINE publishes a compatible dimmer list at www.liteline.com/lunadimmers. Listed accessories (sold separately) include the P-3520 round pre-mounting plate and P-3520NC new construction plate with driver attachment clip for 3½" LUNA fixtures, the P-NCMK-1 new construction mounting kit with hanger bars and brackets, the RA35-XLRING-WH, RA35-XLRING-BK and RA35-XLRING-BN reducer rings, the VBE-1 vapour barrier extender for new construction and VBE-2, VBE-3, VBE-4 for remodel work — the answer to every
recessed lighting vapor barrier question on a Canadian job site — plus the LC-CRTL-DIM-1 smart Wi-Fi dimmer, 120V.
