Built to last, built to aimThe LUNA™ square gimbal starts with a durable
airtight aluminum body paired with an adjustable gimbal, so you can tilt the light source and point it at a backsplash, a bookcase or a feature wall. An anodized blue heat sink keeps airflow moving around the LED module, which is exactly what protects colour consistency and output over the long haul. The square trim is finished in white, a low-profile look that disappears into drywall ceilings and pairs well with modern square vents and registers. Fixture dimensions are 4 15⁄16" (125mm) across with a 15⁄16" (34mm) profile, and the required hole cut is Ø 4 3⁄16" (106mm).
Light quality you can seeThis general application
recessed LED downlight uses a 12 watt LED module that maintains uniform intensity and produces up to 1035 lumens — 92 lumens per watt. The typical
CRI of 90 renders colours faithfully, an advantage in kitchens, retail displays, galleries and anywhere merchandise or materials need to look their best. The 3000 K colour temperature stays warm and residential in feel, and the lens delivers a 40° beam spread for controlled, glare-managed pools of light rather than a washed-out ceiling. LM79 and LM80 testing back the photometric and lumen maintenance claims, with a projected life of 70% at 50,000 hours.
Electrical and installationAn extruded aluminum hardwire box houses a 300mA dimmable Class II electronic
LED driver with 100-135V AC, 60Hz input and a power factor of 0.95. An 18" (457mm) FT6 rated cable with a DC 2.1 connector links driver and fixture, and that assembly is 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 attach to virtually any ceiling material — ideal for retrofit work where you don't want to open up the ceiling. Dimming covers 100%-10% with industry standard
TRIAC/ELV dimmers; the gimbal tilts 20° in each direction. Operating temperature range is -20°C~40°C (-4°F~104°F).
