Built to disappear into the ceilingThe LUNA 3.5" platform is built around a durable airtight fixed aluminum body with an anodized blue heat sink that keeps airflow moving around the LED light source — the single biggest factor in how long a
recessed LED downlight holds its output. The trim is finished in white to blend with standard ceilings, and the compact footprint (4 3/8" / 111 mm overall, 15/16" / 34 mm deep at the trim) means it works where deep cans simply won't fit: shallow joist bays, bulkheads, soffits and dropped ceilings. Because it is airtight and approved for direct contact with insulation, it respects the building envelope in well-sealed Canadian homes.
Light quality you can actually seeA 12 W LED module delivers up to 600 lumens with a typical CRI of 90, which is the difference between "lit" and "flattering". Skin tones, stained cabinetry, tile and artwork all read correctly under 90 CRI, and the 57 lumens per watt efficacy keeps energy use far below the halogen cans this fixture replaces. The lens produces a controlled 38° beam spread, ideal for spacing a clean grid of
round downlights down a hallway or over a counter without hot spots or scalloping on the walls.

Wiring, dimming and installationThe extruded aluminum hardwire box houses a 300 mA dimmable Class II electronic driver with 100-135 V 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 installing a dozen
dimmable LED downlights in one afternoon. 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, so the box can sit comfortably above a T-bar grid. Two spring-loaded clips attach the fixture to any ceiling material, and the Ø 3 5/8" (92 mm) hole cut is easy to template. Pair the fixture with an industry-standard TRIAC or ELV dimmer for smooth control; Liteline publishes a compatible dimmer list for the LUNA family.
Where it works, what it pairs with, and the paperworkUse it as general lighting in kitchens, living rooms, bedrooms and finished basements, as a discreet wash in retail change rooms and boutique ceilings, or over covered patios and in bathrooms where a
wet location rated fixture is required. Accessories are sold separately and include round pre-mounting and new construction plates with driver attachment clips for 3½" LUNA LED fixtures, a new construction mounting kit with hanger bars, reducer rings in black, brushed nickel or white, and vapour barrier extenders for new construction or remodel work — a common ask on any
recessed lighting vapor barrier detail. Keep a consistent look across a whole floor by mixing finishes and colour temperatures from the same housing, such as the
brushed nickel RA35-12F-27K-90BN, the
RA35-12F-40K-90BN or the
dim-to-warm RA35-12F-DTW-90BK. The full technical PDF spec sheet is available in the Documentation tab for your submittal package.
