Some downlights just light a room. This one shapes it. The 4" LUNA LED round regressed gimbal recessed fixture from LITELINE, model RA4-12RG-DTW90BK, is the kind of recessed lighting you install once and then keep pointing at whatever matters most — a stone fireplace, a gallery wall, a display shelf, a reception desk. People call it a pot light, a round LED light, a gimbal downlight or simply a 4-inch recessed light, and it answers to all of them. What sets it apart is the regressed gimbal: the light source sits deep inside the black trim, so you see the glow on your wall and not a bright dot in your eye. It is designed for residential and commercial projects alike, which means the same fixture can run through a new basement, a kitchen renovation, a boutique or a dental clinic waiting room without ever looking out of place.

The optical performance is where this LED downlight earns its keep. Liteline's spectrum test report on this LUNA platform measures a colour rendering index of Ra = 92.8, with TM-30 values of Rf = 92 and Rg = 98 — wood grain, skin tones, paint colours and merchandise all read true instead of washed out. The tested sample delivers 899.4 lm of luminous flux at 8.978 W, an efficacy of 100.17 lm/W, so you get generous, usable light from a very modest draw on the circuit. The tested white point lands at CCT = 2687K, a warm, living-room-friendly tone, and colour consistency is held within 1.8 SDCM so a whole ceiling row looks like one matched set rather than a patchwork. The finish on this SKU is black, a trim colour that visually disappears into a dark ceiling and frames the beam beautifully.

This is a natural fit for open-concept living rooms, hallways, kitchens, bedrooms, finished basements and stairwells, and just as much for retail displays, cafés, offices and clinics across Canada — where ceilings are often working hard around ductwork and joists, and where a compact 4" recessed fixture is easier to place than a big can. Want the same fixture in another trim colour? Look at the 4" Luna round regressed gimbal recessed fixture in white or the brushed nickel version. Ready to aim your light exactly where you want it?

Built around the regressed gimbal
The whole idea behind the LUNA RA4-12RG series is comfort. The LED module is set back inside the housing rather than flush with the ceiling plane, which keeps the bright emitting surface out of your direct line of sight. Add the gimbal action and you can tilt and rotate the light to graze a wall, highlight artwork, or push light into a corner that a fixed downlight would never reach. In a 4-inch aperture, that combination gives you an architectural look without an architectural budget or a specialist to aim it — a screwdriver, a ladder and five minutes of tweaking usually does it.

Light quality you can actually see
Liteline's spectrum test report for this LUNA platform is unusually detailed, and it is worth reading. Colour rendering comes in at Ra = 92.8 with an average R value of 90.9, and the TM-30 metrics report Rf = 92 for fidelity and Rg = 98 for gamut — meaning colours are rendered faithfully and with natural saturation, not artificially punched up. Individual samples are strong across the board, including R9 = 55.97 on deep red, R13 = 94.20 on skin tone and R14 = 99.57 on foliage green. For a kitchen where food should look appetizing, a bathroom mirror where makeup needs to be judged correctly, or a shop where fabric and finishes are being sold, that level of high CRI performance is the difference between a room that feels expensive and one that feels flat.

Electrical and installation notes
The tested electrical values on this platform are V = 33.241 V and I = 0.2701 A at the module, with a power factor of 1.000 — a clean load that plays nicely on a shared branch circuit when you are running several recessed downlights off one switch. Because the draw per fixture is small, you can build a full ceiling layout without crowding the circuit. As with any recessed can, plan your spacing before you cut: a tighter pitch for general ambient light, a wider pitch when you are using the gimbal purely for accenting. Keep the gimbal tilt modest on wall washing so the beam grazes the surface rather than hitting it head-on, and aim all fixtures in a run the same way for a clean, intentional look. Always confirm your installation with the current Canadian Electrical Code and your local inspector, particularly for ceiling assemblies that require an air-tight or vapour barrier treatment.

Family, applications and documentation
This SKU belongs to a full LUNA RA4-12RG family, so you can mix and match across a project while keeping the same aperture and look: the black RA4-12RG-90BK and the white RA4-12RG-90WH cover standard white-light needs, while the Luna 4" OnCloud tunable white and the Luna 4" OnCloud RGBTW bring colour and white-tone control to the same housing style. Typical jobs: a living room where four gimbals wash a feature wall, a retail floor where each fixture is aimed at a different display, an office corridor, a stairwell, a basement rec room. The technical PDF (RA4-12RG-DTW90BK Spec Sheet) is available in the Documentation tab of this page — download it before you order so your electrician has the measured photometric and electrical data in hand.
