Built to last, built to aimThe LUNA 4" gimbal starts with a durable
airtight aluminum body and an adjustable gimbal that tilts 20° in either direction, so you can point light at a backsplash, a bookcase or a feature wall instead of settling for whatever falls straight down. An anodized blue heat sink sits behind the LED module to maximize airflow and keep the light source cool, which is exactly what protects long-term output. Two spring-loaded clips hold the fixture in any ceiling material, and the compact housing measures 5 1/16" (128 mm) across the trim, 4 3/16" (106 mm) at the body, with a 3 3/8" (85 mm) depth and a 2" (51 mm) profile — easy to fit in tight joist spaces where a traditional
recessed can light simply will not go.
Light quality and colour selectionThe LED module maintains uniform intensity and delivers up to
1111 lumens with a typical
CRI of 96 — high-fidelity colour rendering that flatters finishes, food and faces. The on-fixture
colour selectable switch lets you pick 2700 K, 3000 K, 3500 K, 4000 K or 5000 K before install: 2700 K delivers 995 lumens, 3000 K 1040 lumens, 3500 K 1090 lumens, 4000 K 1110 lumens and 5000 K 1085 lumens. The lens produces a controlled 40° beam spread, and the regressed optics keep glare low so the ceiling reads as light, not as a row of bright dots.
Electrical, driver and installationPower comes from 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 driver and fixture and is approved for use in plenums and suspended ceilings. Three "Quick Connect" push-in terminals make wiring fast on a jobsite.
Dimming runs 100%–10% with industry standard forward-phase / reverse-phase and TRIAC/ELV dimmers (contact factory for the compatible dimmer list). The fixture is airtight, suitable for wet locations, approved for direct contact with insulation and for insulated ceiling applications, tested with insulation up to R60, and rated for operating temperatures from -20°C to 40°C (-4°F to 104°F). A VBE vapour barrier extender is recommended in spray foam and loose fill applications.

Applications, accessories and documentationThink kitchen perimeters and islands, bathroom and shower zones, covered entries and soffits, stairwells, home theatres, retail displays, dental and medical clinics, cafés and offices — anywhere a
4" gimbal downlight can point light with intention. Accessories are sold separately and include pre-mounting and new construction plates for 4" LUNA fixtures (P-4020, P-4020NC, P-4024), the P-NCMK-1 new construction mounting kit with hanger bars and brackets, VBE vapour barrier extenders for new construction and remodel work, and RA4-XLRING reducer rings for 4" LUNA fixtures in black, brushed nickel or white. Mixing finishes or optics in the same project is easy: pair it with the
4" LUNA LED round gimbal recessed fixture RA4-12G-90WH, the black
4" LUNA LED round regressed gimbal recessed fixture RA4-12RG-90BK, or add colour-changing accents with the
LUNA 4" OnCloud RGBTW RA4-12RG-RGBTW-90WH. The full technical
spec sheet is available in the Documentation tab for dimensions, lumen tables and the complete ordering guide.
