Built to disappear into the ceilingThe LUNA 2" square starts with a durable airtight aluminum body and an anodized blue heat sink that maximizes airflow around the LED light source — the kind of thermal design that keeps output and colour stable year after year. The trim is square with regressed optics, a shape contractors reach for when they want a crisp architectural ceiling instead of a row of obvious
pot lights. This unit carries the white (WH) trim finish and the
Dim-to-Warm module; note that the on-fixture 5-position colour selectable switch is not available on DTW versions, since the colour shift happens through the dimmer instead.
Light quality and Dim-to-Warm behaviourThe 7 W LED module maintains uniform intensity and produces up to 700 lumens, with the DTW module rated at 680 lumens. Its colour temperature travels from
3000 K down to 2000 K as you dim, which is why this fixture feels so natural in dining rooms, bedrooms and restaurants — bright and neutral when you need to work, candle-warm when you want to relax. Typical CRI is 96, and independent photometric testing on the RA2-7F-DTW-90WH module measured a CRI of 98.2 with R9 at 97.3, TM30 Rf of 95.1 and a measured 2822 K, at 6.9 W and 499 lm for 73 lumens per watt. The 40° beam spread and a tested beam angle of 43.3° give clean, controlled pools of light with low glare.

Wiring and installationMounting is fast: two spring-loaded clips grip any ceiling material, so remodel installs go up through a Ø 2½" hole without opening the drywall. The extruded aluminum hardwire box holds a 170 mA dimmable Class II electronic LED driver, and three
Quick Connect push-in terminals make the wiring straightforward. 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 — but it is not approved for branch wiring. The luminaire is airtight, approved for direct contact with insulation and suitable for indoor/outdoor applications, so it works under soffits, on covered porches and in bathrooms. Optional accessories listed by Liteline include a new construction mounting kit with pre-mounting plate and hanger bars, butterfly brackets, a 60" flexible connector to extend the distance between fixture and driver, a vapor barrier, and a commercial grade driver (120~347V / 120~277V, 0-10V dimming).
Where to use it, and what pairs with itThink kitchen perimeters and islands, hallway runs, stair nosings, closet and pantry lighting, bathroom vanities and shower areas, wall niches in boutiques, clinics and small offices, plus covered outdoor entries. Because LUNA is also offered in 3", 3.5", 4" and 5" or 6", you can keep one aesthetic through a whole house or storefront. For matching trims in the same 2" square format, see the
colour selectable white version, the
brushed nickel version, or the
Dim-to-Warm black trim version. The full technical PDF (RA2S-7F-DTW90WH Spec Sheet) is in the Documentation tab, with photometrics, dimensions and the ordering guide for your submittal package.
