Built to last, built to install fastThe LUNA 3.5" fixed downlight starts with a durable airtight fixed
aluminum body and an anodized blue heat sink that maximizes airflow around the LED light source — the single biggest factor in how long a small
recessed LED fixture keeps its brightness and colour. Two spring-loaded clips hold the housing in any ceiling material, so a retrofit into existing drywall, plaster or a T-bar ceiling takes minutes with a 3 5/8" (92 mm) hole saw. The white trim finish (WH) sits flush and paint-friendly against the ceiling, and the fixture measures 4 3/8" (111 mm) in diameter by 3 3/8" (85 mm) high, with a hardwire box footprint of 4 3/16" (106 mm) x 3 1/16" (78 mm) x 15/16" (34 mm).
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, which is what separates a flattering room from a flat one. This SKU is the 3000 K version, and its colour temperature dims from
3000 K down to 2000 K as you dial the dimmer back — perfect for a dining room that needs to be bright at supper and candle-like at 10 p.m. The lens gives a controlled 38° beam spread, tight enough to graze a wall or wash a counter without spilling light everywhere. LM79 and LM80 tested, with a projected life of 70% at 33,000 hours.
Electrical 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. 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. Three "Quick connect" push-in terminals make wiring fast — a real time-saver when you are installing a dozen
dimmable LED downlights in one afternoon. Use industry-standard
TRIAC/ELV dimmers; Liteline publishes a compatible dimmer list at liteline.com/lunadimmers.

Applications, accessories and documentationBecause it is rated for wet locations and approved for direct insulation contact, this downlight handles showers, covered porches, soffits and insulated attics as easily as a living room ceiling — and the -20 °C to 40 °C range means it keeps working through a Québec or Prairie winter. Accessories are sold separately: the P-3520 round pre-mounting plate and P-3520NC new construction plate with driver attachment clip are made for 3½" LUNA LED fixtures, the P-NCMK-1 kit adds hanger bars and brackets, VBE-1 through VBE-4 vapour barrier extenders cover new construction and remodel work, and RA35-XLRING-WH, -BK or -BN reducer rings adapt the aperture. To keep a whole floor consistent, pair this fixture with the
brushed nickel RA35-12F-DTW-90BN, the
black RA35-12F-DTW-90BK or the
RA35-12G-90WH. The full technical PDF (RA35-12F-30K-90WH Spec Sheet) is in the Documentation tab for dimensions, ordering guide and accessory codes.
