RAB ND22-50-8RW 8 in Round Open Modular Commercial Downlight — 50/40/30W / 30°–50° Adjustable Beam / 120–277V / White

The RAB ND22-50-8RW is a high-output modular commercial downlight combining the ND22-50 light engine with the ND22T-8RW 8 in round open trim (white flange, white reflector). Delivers 4,500/3,800/2,900 lm at 50/40/30W with a field-adjustable beam from 30° to 50° via rotating lens assembly — optimized for wide-area commercial illumination in large spaces. CCT and wattage are field-selectable via dip switch. Universal 120–277V input. Suitable for retrofit, remodel, and new construction — accommodates up to 2 in ceiling thickness.

Light Output & Performance

Engineered for high-output commercial spaces, the ND22-50-8RW delivers 4,500 lm at 50W (90 lm/W), 3,800 lm at 40W (95 lm/W), or 2,900 lm at 30W (96.7 lm/W) — selectable in the field to match the exact demands of the space. With a CRI of 92–95 and R9 >50, colors render with exceptional vibrancy and accuracy across all CCT settings. The <4-step MacAdam Ellipse binning ensures consistent fixture-to-fixture color uniformity, while the 30°–50° adjustable beam is optimized for wide-area illumination in lobbies, atriums, and large commercial interiors. Color temperature is warranted to shift no more than 200K over 5 years.

Electrical & Installation

Built for high-demand commercial environments, the ND22-50-8RW operates on universal 120–277V input with a constant current Class A driver running at 417mA (120V) / 240mA (208V) / 208mA (240V) / 181mA (277V). Supports both TRIAC/ELV dimming to 10% at 120V and 0–10V dimming to 10% across 120–277V, making it compatible with virtually any commercial dimming infrastructure. THD ≤20%, PF ≥0.9 at 120V / ≥0.7 at 277V, flicker ≤30%. Air tight certified per ASTM-E283. Not IC rated. Rated for operation from -4°F to 104°F. Installs in retrofit, remodel, or new construction ceilings up to 2 in thick with a 7.5 in cut-out.
