Built to last in a tight ceilingThe LUNA 3" gimbal starts with a durable
airtight aluminum body and an adjustable gimbal yoke that lets the optic tilt within the trim. Inside, an anodized blue heat sink maximizes airflow around the LED light source, which is what keeps output and colour stable over the long run in a small
recessed downlight. Two spring-loaded clips hold the fixture to any ceiling material, and the compact format — 3 31/32" (85 mm) outside, 2 5/16" (59 mm) deep, with a 1 7/8" (48 mm) and 4 5/8" (117 mm) footprint on the driver box side — slips into shallow cavities where a full housing simply will not go.
Light quality you can seeThe 7 watt LED module maintains uniform intensity and produces up to
745 lumens, a very efficient 96 lumens per watt. A typical
CRI of 90 means whites stay clean and reds stay rich — a real difference in kitchens, bathrooms, retail displays and anywhere people look closely at colour. The lens shapes a 45° beam spread, tight enough to be directional but wide enough to overlap comfortably when fixtures are laid out on a grid. Tilt the gimbal up to 30° to aim at a backsplash, a feature wall, shelving or a piece of art.
Electrical, dimming and installationThe extruded aluminum hardwire box houses a 170 mA dimmable class II electronic
LED driver with 100-135V AC input, connected to the fixture by an 18" (457 mm) FT6 rated cable with a DC 2.1 connector — approved for use in plenums and suspended ceilings. Three "Quick connect" push-in terminals make wiring fast on site, a real time-saver when a contractor is installing a dozen units in one afternoon. Cut a Ø 2 3/4" (70 mm) hole, make your connections, squeeze the clips and you are done. The fixture is
dimmable on TRIAC/ELV dimmers; Liteline publishes a compatible dimmer list at liteline.com/lunadimmers.

Applications, accessories and documentationThink open-concept kitchens with a row of gimbals angled at the counter, a hallway in a Montréal condo, a basement rec room with low joists, a shower or covered entry where the wet location rating matters, or a small clinic and boutique that need clean, high-CRI accent light. Accessories are sold separately and are made for this family: the SLM-60-FC 60" flexible connector for use with SlimLED and LUNA fixtures, the P-2810 2 3/4" round pre-mounting plate with driver attachment clip for 3" LUNA LED fixtures, the P-NCMK-1 new construction mounting kit with hanger bars, brackets and screws, and the VBE-1, VBE-2 and VBE-5
vapour barrier extenders for new construction and remodel work. For smart control, the LC-CRTL-DIM-1 OnCloud Smart Wi-Fi dimmer (120V) and the LC-CRTL-3WAY-1 OnCloud Smart Wi-Fi 3-way switch work with the WiZ App. Need a different colour temperature or finish on the same project? See
