Construction and designThe LUNA 3" square gimbal is built around a durable
airtight aluminum body with an adjustable gimbal head, so you can point the light instead of settling for whatever the ceiling gives you. An anodized blue heat sink sits behind the LED source to provide maximum airflow, which is exactly what keeps output and colour stable year after year in a sealed ceiling cavity. The square trim in black gives a sharp, architectural look that reads as deliberate on white drywall and quietly vanishes on dark ceilings, which is why designers keep specifying this
square recessed LED over a round aperture in modern interiors.
Light qualityThe 7 watt LED module maintains uniform intensity and produces up to 745 lumens, a genuinely useful level for a 3" aperture. A typical
CRI of 90 renders colour honestly, so cabinetry, tile, fabric and food look natural rather than washed out, and the fixed
3000 K colour temperature stays in that comfortable warm-white zone most homeowners ask for. The lens delivers a 45° beam spread for controlled pools of light with soft edges, ideal for an even ceiling grid or for accenting a specific surface once the gimbal is tilted.

Electrical and installationWiring is refreshingly simple: an extruded aluminum hardwire box houses the class II electronic driver and offers three
quick-connect push-in terminals for fast connections. 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, a real advantage in commercial ceilings. Two spring-loaded clips let the trim attach to virtually any ceiling material, and the Ø 2 3/4" (70 mm) hole cut keeps drywall repairs minimal on a
retrofit. Because it is wet location rated and approved for direct contact with insulation, it can go under a covered entry, in a shower ceiling or straight into an insulated attic without an extra enclosure. Pair it with any industry standard TRIAC/ELV dimmer for smooth control.
Applications, compatibility and documentationThink kitchen perimeters and islands, hallways, walk-in closets, stairwells, bathrooms, covered porches, and on the commercial side retail displays, reception desks, restaurant booths and clinic corridors. Accessories such as vapour barrier extenders, a new construction mounting kit and a round pre-mounting plate for 3" LUNA LED fixtures are sold separately, which makes this
3 inch gimbal downlight equally at home in new construction and remodel work. Within the same family you can match finishes and temperatures using the
3" Luna LED square gimbal RA3S-7G-27K-90BK, the
3" Luna LED square gimbal RA3S-7G-35K-90BK, or the dim-to-warm
3" Luna square gimbal RA3S-7G-DTW-90WH in white. The full technical spec sheet is available in the Documentation tab for cut dimensions, driver details and certification references.
