Built to disappear into the ceilingThe LUNA 3.5" square fixed recessed fixture uses a durable
airtight fixed aluminum body with an anodized blue heat sink that keeps airflow moving around the LED source — the simplest way to protect light output and colour over the years. Two spring loaded clips hold the fixture to any ceiling material, so it works in drywall, plaster, T-bar ceilings or wood. The square face measures 4 3⁄8" (111 mm) and the housing steps in to 3 3⁄8" (85 mm), with an overall depth reference of 15⁄16" (34 mm) at the trim and additional dimensions of 4 3⁄16" (106 mm) and 3 1⁄16" (78 mm) on the body. Required hole cut is Ø 3 5⁄8" (92 mm).
Light quality and dim-to-warmThe 12 watt LED module delivers up to
600 lumens of uniform intensity with a typical
CRI of 90, which is the level interior designers ask for in kitchens, bathrooms and retail displays. The lens produces a 38° beam spread, tight enough for accent rows over counters, wide enough for general ceiling layouts. Colour temperature runs from 3000 K down to 2000 K as you dim, so evening light gets warmer and cosier exactly the way an incandescent used to behave — a detail your clients notice immediately in dining rooms and bedrooms.
Electrical and installationPower comes from an extruded aluminum hardwire box housing a 300 mA dimmable
class II electronic driver with 100-135V AC input. 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 on site — a real time saver when you're installing a dozen units in a day. The fixture is compatible with industry standard
TRIAC/ELV dimmers; Liteline publishes its compatible dimmer list at liteline.com/lunadimmers. Operating temperature range is -20°C to 40°C (-4°F to 104°F) and power factor is greater than 0.90.

Applications, accessories and documentationBecause it is
suitable for wet locations and approved for direct contact with insulation, this downlight handles showers, covered porches, entry soffits and insulated attic ceilings as easily as a living room. Typical projects: a kitchen ceiling grid over island and perimeter counters, basement renovations with low joist depth, condo corridors, boutiques, dental and medical clinics, small offices and cafés. Accessories are sold separately, including the P-3520 3 5⁄8" round pre-mounting plate with driver attachment clip for 3½" LUNA LED fixtures, the P-NCMK-1 new construction mounting kit with hanger bars, brackets and screws, and the VBE-1 to VBE-4
