Built to last, built to disappearThe LUNA Designer Series was evolved to be a flexible, low-glare and aesthetically pleasing luminaire, and the RA35S-12RG-90BN shows it. The housing is a durable
airtight aluminum body with an adjustable regressed gimbal, and an anodized blue heat sink provides maximum airflow for the LED light source — the kind of thermal management that keeps output and colour steady year after year. The regressed optic pulls the light source back from the ceiling plane, cutting the hot-spot glare you get from flush lenses, while the Brushed Nickel trim (BN) gives a refined metallic edge to the
square recessed fixture format. Overall dimensions are 4 3/8" (111 mm) and 3 3/8" (85 mm), with a 3 1/16" (78 mm) and 4 3/16" (106 mm) profile and a 15/16" (34 mm) depth detail, for a 3 5/8" (92 mm) hole cut.
Light quality you can actually seeThe LED module maintains uniform intensity and produces up to 1160 lumens with a typical
CRI of 95+ — a level of colour rendering that makes whites crisp, woods warm and merchandise honest. The on-fixture
colour selectable switch offers five CCTs (2700 K, 3000 K, 3500 K, 4000 K, 5000 K), so one SKU covers a warm living room, a neutral kitchen and a crisp commercial space. Lumen output by CCT: 1040 lm (2700 K), 1090 lm (3000 K), 1135 lm (3500 K), 1160 lm (4000 K) and 1145 lm (5000 K). The lens delivers a 38°
beam spread and the gimbal tilts up to 40°, ideal for grazing a feature wall or picking out art.
Electrical and installationThe extruded aluminum hardwire box carries a 12 watt (300mA) dimmable class II electronic LED driver with 100-135V AC input, plus an 18" (457 mm) FT6 rated cable with DC 2.1 connector between driver and fixture, approved for use in plenums and suspended ceilings. Three
quick connect push-in terminals speed up wiring, and two spring-loaded clips attach the fixture to any ceiling material. Dimming runs 100%-10% and the fixture is compatible with industry standard forward-phase / reverse-phase and
TRIAC/ELV dimmers (contact factory for the list of compatible dimmers). Operating temperature range: -20°C~40°C (-4°F~104°F). Power factor >0.90.

Where it works and what's in the box of documentsAirtight construction, direct contact with insulation and a wet location rating make this
gimbal downlight a natural choice for insulated ceilings, bathrooms and showers, covered entries and porches, basements and condos — all the spots a Canadian renovation throws at you. Commercially, think boutiques and display cases, restaurants, hotel corridors, clinics and offices where a tight 38° beam and CRI 95+ make products and finishes pop. Accessories are sold separately, including vapour barrier extenders for new construction and remodel work, round pre-mounting and new construction plates for 3 1/2" LUNA LED fixtures and a new construction mounting kit with hanger bars — useful when your
recessed lighting vapour barrier detail has to pass inspection. Matching the rest of the ceiling is easy: pair it with the fixed-optic
3.5" Luna LED square recessed fixture RA35S-12F-27K-90BN, or choose the dim-to-warm version, the
RA35S-12RG-DTW90BN. The full technical PDF spec sheet is available in the Documentation tab for cut sheets, submittals and dimensions.
