Built to last, built to installThe LUNA 3.5" starts with a durable
airtight fixed aluminum body and an anodized blue heat sink that keeps air moving around the LED light source — the simplest way to protect lumen output over the long haul. Two spring-loaded clips let the fixture bite into any ceiling material, so a
retrofit recessed downlight install in existing drywall takes minutes with a Ø 3 5⁄8" (92 mm) hole cut. The extruded aluminum hardwire box keeps the driver tidy above the ceiling, and the compact footprint (4 3⁄8" / 111 mm overall, 3 3⁄8" / 85 mm) tucks into tight joist bays and shallow plenums.
Light quality and dim-to-warmThe 12 watt LED module produces uniform intensity with up to
600 lumens and a typical
CRI of 90, which is the difference between a kitchen that looks flat and one where the backsplash, countertops and cabinetry read properly. Colour temperature
dims from 3000 K to 2000 K, mimicking the warm shift of incandescent as you turn the dimmer down — great for dining rooms, bedrooms, restaurants and hotel-style ambiance. The lens delivers a controlled
38° beam spread, clean enough to space evenly down a hallway or to graze a feature wall.

Wiring, dimming and compatibilityPower comes from a
300 mA dimmable Class II electronic LED driver with 100-135V AC input, connected to the fixture by an 18" (457 mm) FT6 rated cable with a DC 2.1 connector approved for use in plenums and suspended ceilings. Three
Quick Connect push-in terminals mean no wire nuts and fast daisy-chaining across a run of downlights. Use an industry-standard
TRIAC or ELV dimmer for smooth dim-to-warm control. Accessories listed for this family are sold separately and include the P-3520 round pre-mounting plate and 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, the VBE-1 to VBE-4 vapour barrier extenders (a real answer to the "recessed lighting vapor barrier" question in Canadian builds), the RA35-XLRING-BN, RA35-XLRING-BK and RA35-XLRING-WH reducer rings, and the LC-CRTL-DIM-1 smart Wi-Fi dimmer, 120V.
Where to use it, and documentationThink kitchen downlights over an island, a rhythm of small apertures in a hallway, bathroom and covered-entry ceilings where a
wet location rating is mandatory, plus offices, salons, boutiques and restaurant ceilings that need a quiet, high-CRI look. Approved for direct contact with insulation, it also suits insulated ceilings in cold-climate Canadian homes. Need other finishes or the standard LUNA versions? See the
