Built to disappear into the ceilingThe LUNA Designer Series was developed around one idea: a flexible, low-glare, good-looking luminaire that contractors, builders, homeowners and designers can all agree on. The RA35S-12RG-90WH uses a durable airtight aluminum body with an adjustable regressed gimbal, plus an anodized blue heat sink that provides maximum airflow for the LED light source — the kind of thermal design that helps an LED hold its output year after year. The square white trim sits tight to the ceiling, while the regressed optic pushes the light source deep inside, so what you see is the light on your surfaces rather than a bright dot in your eyes.
Light quality you can trustThis general application fixture features an LED module that maintains uniform intensity, producing up to 1160 lumens with a typical CRI of 95+. The on-fixture colour selectable switch gives you five white tones — 2700 K, 3000 K, 3500 K, 4000 K and 5000 K — meaning one SKU covers a warm residential living room and a crisp commercial back-of-house. Measured output at 12W is 1040 lumens at 2700 K, 1090 at 3000 K, 1135 at 3500 K, 1160 at 4000 K and 1145 at 5000 K. The lens delivers a 38° beam spread and the gimbal tilts 40° with 20° of visible rotation each way, ideal for grazing a stone wall or highlighting artwork and shelving.

Electrical and installationThe fixture is fed by an extruded aluminum hardwire box housing a 12 watt (300 mA) dimmable Class II electronic LED driver with 100-135V 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, so you can tuck the box neatly above a T-bar grid. Three quick-connect push-in terminals speed up wiring, and two spring-loaded clips attach the housing to any ceiling material — drywall, plaster or panel. Because the body is airtight and approved for direct contact with insulation, it can go straight into an insulated attic ceiling; accessories such as vapour barrier extenders, pre-mounting plates and new construction mounting kits exist for these 3 1/2" LUNA LED fixtures and are sold separately. Dimming runs 100% to 10% on industry standard forward-phase / reverse-phase and TRIAC/ELV dimmers.
Where it works and what to readThink kitchens and islands, bathrooms and showers (wet location rated), hallways, staircases, basements with limited plenum depth, covered exterior soffits, plus retail shops, salons, clinics, restaurants and offices where a 95+ CRI and an aimable beam make merchandise and finishes look their best. Mixing flat and gimbal versions on the same ceiling keeps a consistent aperture: use the
3.5" Luna LED square recessed fixture for general wash and this regressed gimbal for accents, or specify
black or
brushed nickel trims for darker ceilings. The full technical PDF spec sheet for RA35S-12RG-90WH is available in the Documentation tab for your plans, submittals and inspections.
