Built to disappear into the ceilingThe LUNA Designer Series was evolved to be a flexible, low-glare and aesthetically pleasing luminaire, and the regressed gimbal version is the proof. A durable
airtight aluminum body houses an adjustable regressed gimbal, while an anodized blue heat sink keeps maximum airflow around the LED light source — the single best way to protect lumen output and colour over the years. The black trim finish (BK) sinks visually into dark ceilings and cuts reflected sparkle, which is exactly what you want in a media room, a restaurant or a hotel corridor. Two spring-loaded clips are included and grip any ceiling material, and the fixture is approved for direct contact with insulation, so no standoff boxes to build.
Light quality and aimingThis is a
colour selectable (5CCT) recessed downlight: an on-fixture switch steps through 2700 K, 3000 K, 3500 K, 4000 K and 5000 K, so a single SKU handles a warm master bedroom and a cool garage workbench on the same job site. Output tracks the setting — 1040 lumens at 2700 K, 1090 at 3000 K, 1135 at 3500 K, 1160 at 4000 K and 1145 at 5000 K — for up to 102 lumens per watt. With a typical
CRI of 95+, merchandise, artwork and finishes read true. The lens delivers a 38° beam spread and the gimbal tilts up to 40°, so you can wall-wash, accent a fireplace or correct for a sloped ceiling without buying a second fixture type.

Wiring and installationThe extruded aluminum hardwire box holds a 12 watt (300mA) dimmable Class II electronic LED driver with 100-135V AC input. Three
"Quick connect" push-in terminals make wiring fast, and an 18" (457 mm) FT6 rated cable with a DC 2.1 connector links driver to fixture — approved for use in plenums and suspended ceilings, which matters for commercial inspections. Cut a Ø 3 5/8" (92 mm) hole, clip it in, aim, done. Pair it with industry standard forward-phase / reverse-phase and TRIAC/ELV dimmers for smooth 100%-10% control; contact factory for the list of compatible dimmers. Accessories such as pre-mounting plates, new construction plates and mounting kits, vapour barrier extenders and reducer rings are listed on the spec sheet and sold separately.
Where it works, and what pairs with itBecause it is airtight, IC-rated for insulation contact and suitable for wet locations, this LUNA suits Canadian realities: insulated attics, bathrooms and shower ceilings, covered entries and soffits, basements, open-plan kitchens, plus retail, offices, clinics and hospitality. Build a consistent ceiling by mixing this gimbal with the fixed-trim
3.5" Luna LED round recessed fixture RA35-12F-30K-90WH for general lighting, or stay in the gimbal family with
3.5" Luna LED round regressed gimbal recessed fixture RA35-12RG-90WH and
3.5" Luna LED round regressed gimbal recessed fixture RA35-12RG-90BN for other finishes — all share the same Ø 3 5/8" (92 mm) hole cut. The full technical PDF (RA35-12RG-DTW90BK Spec Sheet) is in the Documentation tab with dimensions, lumen table and the complete ordering guide.
