A regressed gimbal built for comfortThe whole point of the LUNA
regressed gimbal recessed fixture is visual comfort. On a flat-trim downlight, the light source sits close to the ceiling and you see it from across the room. Here the LED is set back inside the aperture and mounted on a gimbal ring, so the bright source is shielded by the trim while the beam still tilts. The result is a ceiling that reads as a series of soft dark circles when you're not standing under it, and a crisp pool of light when you are. That's why designers reach for regressed
4-inch pot lights in open-concept spaces where you sit and look up at the ceiling all evening.
Light quality you can measureThe spectrum test report for this model documents a warm
2700K output — chromaticity coordinates x = 0,4623, y = 0,4132, measured CCT 2687K with a Duv of 0,0008, right on the ANSI 2700K target. Colour rendering comes in at Ra = 92.8 with an average R value of 90.9, R1 through R15 ranging from 55.97 (R9, deep red) to 99.57 (R14), and TM-30 fidelity Rf 92 with gamut Rg 98. Colour consistency is rated at
1.8 SDCM, which matters enormously when you install ten or twenty fixtures in the same ceiling and don't want one of them looking pink. Peak wavelength is 623.0 nm with a FWHM of 139.6 nm and a dominant wavelength of 584.0 nm.

Installation and aimingPlan your layout before you cut: a row of gimbals along a wall will wash art and millwork, while a centred grid gives you even general lighting. Because the head tilts, you can correct the aim after the drywall is up — handy when a kitchen island ends up a little off-centre from the framing. Keep the spacing consistent from one fixture to the next so the scallops on the wall line up, and set all the gimbals to the same angle with a level or a laser for a clean, professional look. As with any recessed work, confirm ceiling depth, insulation contact requirements and dimmer compatibility with your electrician before you order quantities, and follow the manufacturer's instructions supplied with the fixture.
Where it works and what pairs with itUse these gimbals over a kitchen counter, along a hallway of family photos, above a bathroom vanity zone, in a finished basement or across a boutique's merchandising wall — anywhere
surface and recessed downlighting needs to be aimable. For projects that call for colour-changing or white-tuning control on the same 4" platform, look at the
Luna 4" OnCloud tunable white or the
Luna 4" OnCloud RGBTW, and mix finishes with the
black version of this fixture. The
technical spec sheet for RA4-12RG-90WH is available in the Documentation tab for your electrician, inspector or lighting plan.
