Built to last, built to install fastThe LUNA RA3S-7G-DTW-90BK is made around a durable airtight aluminum body with an adjustable gimbal, plus an anodized blue heat sink that maximizes airflow around the LED light source — the single biggest factor in how long a recessed fixture really lasts. Two spring loaded clips hold it in any ceiling material, and the square black trim sits flush for a clean, architectural finish. The 3" format only needs a Ø 2¾" (70 mm) hole cut, so it slips between joists and into tight bulkheads where a bigger can simply won't go.
Light quality you can seeThe 7 watt LED module produces up to 745 lumens of uniform intensity at 96 lumens per watt, with a typical CRI of 90 for rich, accurate colour. What sets this SKU apart is dim-to-warm: as you lower the dimmer, the colour temperature travels from 3000 K down to 1800 K, mimicking the cozy amber of an incandescent or candle flame. The lens delivers a 45° beam spread and the gimbal tilts up to 30°, so you can wall-wash, graze a texture or highlight a countertop instead of just flooding the floor. The fixture is LM79 and LM80 tested, with a projected life of 70% @ 33,000 hrs.
Electrical and installation detailsPower comes from an extruded aluminum hardwire box with a 170 mA dimmable Class II electronic LED driver, 100-135V AC input and a 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're installing a dozen downlights in one afternoon. The fixture is dimmable with industry standard TRIAC/ELV dimmers, and Liteline publishes a compatible dimmer list at liteline.com/lunadimmers. Operating temperature range is -40°C to +40°C (-40°F to +104°F).

Applications, accessories and documentationThink kitchen perimeters and islands, hallway runs, stair landings, basement renovations, walk-in showers and covered entries at the cottage; in commercial work, it suits boutique retail, café and restaurant seating areas, salons, clinics and small offices where a
square surface-look downlight needs to stay subtle. Because it is approved for direct contact with insulation and for wet locations, it is a safe choice for insulated ceilings and damp rooms across Canada. Accessories are sold separately and include 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, the SLM-60-FC 60" flexible connector, and the VBE-1 to VBE-4 vapour barrier extenders for new construction and remodel work. Matching finishes and fixed colour temperatures are available in the same family, such as the
3500 K black gimbal and the
3000 K white gimbal. The full technical spec sheet for RA3S-7G-DTW-90BK is in the Documentation tab — download it before you cut your ceiling.
