Built to last, built to hideThe LUNA 3" gimbal starts with a durable airtight aluminum body and an adjustable gimbal that lets you tilt the optic after the ceiling is closed. Inside, an anodized blue heat sink maximizes airflow around the LED light source, which is how a compact
3 inch LED pot light keeps its output stable year after year. Two spring loaded clips hold the fixture in place and let it attach to any ceiling material, from drywall to tongue-and-groove to a suspended ceiling tile. Because the housing is airtight and approved for direct contact with insulation, it belongs in insulated ceilings without a separate box.
Light quality you can seeThe 7 watt LED module produces uniform intensity up to 745 lumens, a real 96 lumens per watt, with a typical CRI of 90 for honest colour rendering on cabinetry, tile, paint and merchandise. The lens delivers a 45° beam spread — wide enough to layer evenly on a ceiling grid, tight enough to accent. Colour temperature is 3000 K, the warm-neutral white most Canadian homeowners ask for in kitchens, baths and living areas, and it stays consistent across every fixture on the run.

Wiring, dimming and installationPower comes from a 170mA dimmable class II electronic LED driver housed in an extruded aluminum hardwire box with three quick connect push-in terminals, so wiring is fast even overhead on a ladder. An 18" (457mm) FT6 rated cable with a DC 2.1 connector links the driver to the fixture and is approved for use in plenums and suspended ceilings. For
dimmable recessed lighting, pair it with industry standard TRIAC/ELV dimmers; Liteline publishes a compatible dimmer list at liteline.com/lunadimmers. Useful accessories are sold separately and include the SLM-60-FC 60" flexible connector for SlimLED and LUNA fixtures, the P-2810 2¾" 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, vapour barrier extenders VBE-1, VBE-2 and VBE-5, and the OnCloud smart Wi-Fi controls LC-CRTL-DIM-1 dimmer (120V) and LC-CRTL-3WAY-1 3-way switch, both compatible with the WiZ App.
Where it works and what else to look atUse rows of these gimbals to wash a hallway, aim them at a stone fireplace or a gallery wall, tuck them into a shower or over a tub thanks to the wet location rating, light a covered porch or soffit, or build a clean grid in a condo, dental clinic, boutique or restaurant. If your project calls for the same body with colour temperature dimming from 3000 K down to 1800 K, look at the dim-to-warm versions:
