Built to last, built to breatheThe LUNA Designer Series starts with a durable airtight aluminum body fitted with an adjustable
regressed gimbal. An anodized blue heat sink sits behind the LED module to maximize airflow and keep junction temperatures in check — the real secret behind a projected life of 70% at 50,000 hours. The trim measures 4 3/8" (111mm) square at the ceiling and 3 3/16" (78mm) in depth behind it, with a 3 5/8" (92mm) hole cut, so this
square LED pot light drops into tight joist bays, sloped soffits and renovation ceilings without drama. Two spring-loaded clips grip any ceiling material, from drywall to wood plank.
Light quality you can seeRegressing the optic pushes the source up and away from your line of sight, which is what makes this fixture so comfortable to sit under. The 38° beam spread is tight enough to sculpt and wide enough to cover, and the gimbal tilts 40° (20° in each direction) to aim exactly where you want. With a typical
CRI of 95+ and a colour selectable switch right on the fixture, you can set 2700 K for a warm living room, 3000 K or 3500 K for kitchens and hallways, 4000 K for a workshop or garage and 5000 K for a commercial back-of-house — five
selectable colour temperatures in one SKU, decided on site instead of at the order desk.

Wiring and installationThe extruded aluminum hardwire box houses a 12 watt (300mA) dimmable Class II electronic LED driver with 100-135V AC input, and connects to the fixture through an 18" (457mm) FT6 rated cable with a DC 2.1 connector — approved for use in plenums and suspended ceilings. Three "Quick connect" push-in terminals make the line, neutral and ground connections fast, which matters when you are installing twenty
recessed downlights in an afternoon. Because the housing is airtight and approved for direct contact with insulation, no separate IC box is required. On dimmers, stay with industry standard forward-phase / reverse-phase TRIAC/ELV models and always test one fixture on the circuit before finishing the whole ceiling.
Applications, options and documentationThink kitchen islands and perimeter wall-wash, hotel corridors, bathroom and shower ceilings (wet location approved), covered entries and exterior soffits, retail shelving, café counters and clinic waiting rooms. Mix aimable gimbals with fixed trims in the same ceiling for a coherent look: the fixed
