Built to last, built to aimThe LUNA RA4-12G starts with a durable airtight aluminum body wrapped around an adjustable gimbal, so the optic tilts to place light exactly where the design calls for it. An anodized blue heat sink sits behind the LED source to provide maximum airflow and keep operating temperatures in check — the reason a
4" gimbal recessed light like this can be approved for direct contact with insulation and tested with insulation up to R60. The black trim finish (BK) is the quiet choice for dark-painted ceilings, media rooms and modern interiors where you want the light, not the fixture.
Light quality you can seeThe 12 watt LED module maintains uniform intensity and produces up to 1035 lumens at a warm
3000 K, the temperature most Canadian homeowners pick for living spaces. A typical
CRI of 90 renders whites crisp and colours honestly, which matters over a kitchen counter, in a retail display or in a bathroom mirror zone. The lens delivers a 40° beam spread — tight enough to accent, wide enough to lay out on a grid for general
recessed downlighting. At 92 lumens per watt with a 0.95 power factor, it earns its ENERGY STAR qualification and cuts energy dramatically compared with old halogen pot lights.
Electrical, dimming and installationPower comes from an extruded aluminum hardwire box housing a 300 mA dimmable Class II electronic LED driver with 100-135 V AC, 60 Hz input. An 18" FT6-rated cable with a DC 2.1 connector links driver to fixture and is approved for use in plenums and suspended ceilings, and three "Quick connect" push-in terminals make wiring fast on site. Dimming is 100%-10% with industry standard
TRIAC/ELV dimmers. Cut a Ø 4 3⁄16" (106 mm) hole, feed the fixture through and let the two spring-loaded clips lock it into drywall, plaster or panel. Operating temperature range is -20°C~40°C (-4°F~104°F), and the fixture is suitable for
wet locations and insulated ceiling applications.

4 inch pot light beats a fixed downlight. Liteline offers accessories sold separately, including the P-4020 pre-mounting plate and P-4020NC new construction plate for 4" LUNA fixtures, the P-4024 pre-mounting plate, the P-NCMK-1 new construction mounting kit, VBE vapour barrier extenders (VBE-1 for new construction, VBE-2, VBE-3 and VBE-4 for remodel — recommended in spray foam and loose fill applications) and RA4-XLRING reducer rings for 4" LUNA fixtures. Within the family, the
RA4-12G-DTW-90BK dim-to-warm version and the
RA4-12RG-90BK regressed gimbal share the same 4" platform for mixed layouts. The full technical PDF (RA4-12G-90BK Spec Sheet) is in the Documentation tab for dimensions, ordering guide and approvals.
