Built to last, built to aimThe LUNA 3" square gimbal is made around a durable airtight aluminum body with an adjustable gimbal that tilts 30°, so a straight row of trims can still send its beams toward a wall, a countertop or a display. An anodized blue heat sink sits behind the LED to maximize airflow and protect the light source, which is what allows the
projected life of 70% at 33,000 hours and the lifetime warranty. Two spring-loaded clips hold the fixture in any ceiling material, and the compact 2 5/16" (59 mm) height keeps it friendly in tight joist bays and dropped bulkheads. The square trim is offered in black (BK), brushed nickel (BN) and white (WH); this SKU is the black version.
Light quality and dim-to-warmThe 7 watt module produces uniform intensity up to
745 lumens, for 96 lumens per watt, with a typical
CRI of 90 that keeps reds, woods and textiles honest. What sets this model apart is
dim-to-warm behaviour: as you dial the dimmer down, the colour temperature shifts from 3000 K toward 1800 K, so a bright kitchen at dinner prep becomes a soft, amber, restaurant-like room later in the evening — the same feeling incandescent lamps gave, without the heat or the energy bill. The lens holds a controlled 45° beam spread, tight enough to accent, wide enough to light a walkway or a vanity.
Electrical and installationPower comes from an extruded aluminum hardwire box housing a 170 mA dimmable Class II electronic driver, 100-135V AC, 50/60Hz input, 0.95 power factor. An 18" (457 mm) FT6 rated cable with a DC 2.1 connector links driver to fixture and is approved for use in plenums and suspended ceilings. Three Quick Connect push-in terminals make wiring fast — a real time saver when you are installing a dozen trims in one afternoon. Cut a Ø 2 3/4" (70 mm) hole, connect, push the driver box through the opening and squeeze the clips. The fixture is approved for direct contact with insulation and for wet and insulated ceilings, and it dims with industry standard
TRIAC/ELV dimmers; Liteline publishes a compatible dimmer list at liteline.com/lunadimmers.

Applications, accessories and documentationUse it over an island in rows, angled into upper cabinets; in a bathroom or a shower area thanks to the wet location rating; in a finished basement where ceiling height is precious; on a covered porch or soffit; or in a boutique, café, clinic or hair salon where small square apertures look sharper than round ones. Accessories are sold separately: the P-2810 2 3/4" round pre-mounting plate with driver attachment clip is made for 3" LUNA LED fixtures, the P-NCMK-1 new construction mounting kit adds hanger bars, brackets and screws, and VBE-1 through VBE-4 vapour barrier extenders cover new construction and remodel situations — handy for anyone searching
recessed lighting vapour barrier solutions. For smart control, the LC-CRTL-DIM-1 Wi-Fi dimmer and LC-CRTL-3WAY-1 Wi-Fi 3-way switch work with the WiZ App. Need other finishes or a fixed colour temperature? See
