Built to last, built to disappear into the ceilingThe LUNA 3.5" round fixed fixture uses a durable airtight
aluminum body with an anodized blue heat sink that maximizes airflow around the LED light source — the detail that keeps light output stable year after year. The trim is fixed and round, finished here in brushed nickel, with an overall profile of 4 3/8" (111mm) diameter and 3 3/8" (85mm) height, a 4 3/16" (106mm) trim face and a 15/16" (34mm) trim depth. Because it is airtight and approved for direct contact with insulation, it belongs in sealed ceilings where you do not want conditioned air leaking into the attic.
Light quality and dim-to-warmThe
12 watt LED module maintains uniform intensity and produces up to 600 lumens with a typical
CRI of 90, which is what makes food, textiles and finishes look natural instead of washed out. The lens creates a 38° beam spread, tight enough to shape light on a counter or a hallway runner, wide enough for general ambient lighting when the fixtures are spaced in a row. As you dim, the colour temperature travels from
3000 K down to 2000 K, so evening light in a dining room or bedroom becomes genuinely relaxing rather than just dimmer.
Electrical and installationPower comes from a 300mA dimmable Class II electronic
LED driver housed in an extruded aluminum hardwire box, with 100-135V AC input and three quick connect push-in terminals for fast, tool-friendly wiring. An 18" (457mm) FT6 rated cable with a DC 2.1 connector links driver to fixture and is approved for use in plenums and suspended ceilings. Two spring loaded clips attach the housing to any ceiling material through a Ø 3 5/8" (92mm) hole cut. Pair it with standard
TRIAC/ELV dimmers for smooth control; power factor is greater than 0.90 and the operating range is -20°C to 40°C (-4°F to 104°F).

Applications, accessories and documentationThink of rows of these
recessed LED downlights over a kitchen island, in a basement renovation, in a hotel corridor or a clinic waiting room, or in a covered entryway where the wet location rating earns its keep. Accessories are sold separately: the P-3520 round pre-mounting plate and the P-3520NC new construction plate with driver attachment clip are made for 3½" LUNA LED fixtures, the RA35-XLRING-BN reducer ring matches the brushed nickel finish, the P-NCMK-1 new construction mounting kit adds hanger bars and brackets, and VBE-1 through VBE-4 vapour barrier extenders cover new construction and remodel work. For a full ceiling in one finish family, see the
3.5" Luna LED round recessed fixture RA35-12F-DTW-90BN or fixed colour versions such as the
3.5" Luna LED round recessed fixture RA35-12F-27K-90BN and the
3.5" Luna LED round recessed fixture RA35-12F-40K-90BN. The complete technical PDF spec sheet is in the Documentation tab.
