Built to last, built to aimThe LUNA gimbal starts with a durable airtight aluminum body and an adjustable gimbal that tilts 20° to either side, so a single
4" recessed pot light can wash a wall, graze a stone fireplace or highlight shelving without adding a separate accent fixture. An anodized blue heat sink sits behind the LED module to provide maximum airflow to the light source, which is exactly what keeps output and colour stable over the long haul. The fixture measures 5 1/16" (128mm) across the trim with a 4 3/16" (106mm) face, 3 3/8" (85mm) deep plus a 15/16" (34mm) and 2" (51mm) profile, and it installs in a Ø 4 1/4" (108mm) hole cut. The black trim keeps the ceiling visually quiet in dark-painted rooms and modern interiors.
Light quality and colour selectionThe LED module maintains uniform intensity and produces up to 1111 lumens with a typical
CRI of 96 — high-fidelity colour rendering that flatters kitchens, retail displays and bathroom mirrors alike. The on-fixture
color selectable switch offers five colour temperatures: 995 lumens at 2700 K, 1040 lumens at 3000 K, 1090 lumens at 3500 K, 1110 lumens at 4000 K and 1085 lumens at 5000 K on the 12W setting. That means one box on the truck can serve a warm living room and a crisp garage on the same job. The lens delivers a controlled 40° beam spread, and regressed optics keep glare out of sightlines.

Electrical and installationAn extruded aluminum hardwire box houses a dimmable Class II electronic LED driver — 12 watt (300mA) or 9 watt (210mA) — with 100-135V AC input, and an 18" (457mm) FT6 rated cable with a DC 2.1 connector links driver to fixture, approved for use in plenums and suspended ceilings. Three Quick Connect push-in terminals speed up wiring, and two spring-loaded clips let the fixture mount to virtually any ceiling material. It is airtight, suitable for wet locations, approved for direct contact with insulation and tested with insulation up to R60; a VBE vapour barrier extender is recommended in spray foam and loose fill applications, a detail that matters in Canadian builds where
recessed lighting vapour barrier compliance is checked. For new construction, mounting plates, new construction plates and hanger-bar kits are available as accessories, sold separately.
Applications, family and documentationUse rows of these
gimbal downlights to graze a kitchen backsplash, angle them over a retail display wall, tuck them into a covered porch ceiling, or mix straight-down and tilted units in a hallway gallery. Because the LUNA line shares the same 4" platform, you can match finishes and apertures across a whole project: the fixed-CCT
4" LUNA LED round gimbal recessed fixture RA4-12G-30K-90WH, the regressed
4" LUNA LED round regressed gimbal recessed fixture RA4-12RG-90WH and the smart
LUNA 4" OnCloud RGBTW RA4-12RG-RGBTW-90BK all live in the same family. The full technical PDF (RA4-12G-DTW-90BK Spec Sheet) with dimensions, lumen table, ordering guide and accessory list is in the Documentation tab.
