Built to last, built to install fastThe Luna 3" square gimbal starts with a durable airtight aluminum body paired with an adjustable gimbal, so the light aims where the design needs it instead of straight down. An anodized blue heat sink keeps airflow moving around the LED light source, which is how a compact
square recessed downlight keeps its output stable year after year. Two spring loaded clips let the fixture attach to any ceiling material, and the hole cut is Ø 2 3/4" (70mm) — a friendly size for both retrofit and new work. It is approved for direct contact with insulation, so you are not fighting your ceiling insulation on a renovation.
Light quality you can seeThe 7 watt LED module maintains uniform intensity and produces up to
745 lumens, at an efficiency of 96 lumens per watt. With a typical
CRI of 90, colours stay honest: white cabinets read white, warm oak reads warm, and merchandise looks like it does in daylight. The lens delivers a 45° beam spread, tight enough for accenting yet broad enough for general lighting when the fixtures are laid out on a regular grid. LM79 and LM80 testing is on file for this platform, and projected life is 70% @ 33,000 hrs.
Electrical and dimmingPower comes from an extruded aluminum hardwire box housing a 170mA dimmable class II electronic
LED driver with 100-135V AC input, 50/60Hz. An 18" 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. Three quick connect push-in terminals make the wiring quick and clean. Dimming works with industry standard
TRIAC/ELV dimmers; power factor is 0.95. The fixture is cETLus certified, class II, suitable for wet locations, and rated for operating temperatures of -40°C to +40°C (-40°F to +104°F).

Where to use it, and what goes with itThink kitchen islands and toe-kick-free ceilings, ensuite showers, mudrooms, covered entries and soffits, finished basements, boutique shelving, café counters, reception desks and treatment rooms — the wet location rating and insulated ceiling approval cover most Canadian realities, including cold garages and porches thanks to the -40°C rating. Accessories are sold separately and, per the documentation, include the P-2810 pre-mounting plate with driver attachment clip for 3" Luna LED fixtures, the P-NCMK-1 new construction mounting kit and VBE vapour barrier extenders for new construction or remodel work.
