Light Output & Performance

Engineered for commercial precision, the ND22-20-4HRW delivers 1,800 lm at 20W (90 lm/W), 1,500 lm at 16W (93.8 lm/W), or 1,150 lm at 12W (95.8 lm/W) — selectable in the field to match the exact demands of the space. With a CRI of 90–95 and R9 >50, colors render vividly and accurately across all CCT settings. The <4-step MacAdam Ellipse binning ensures consistent fixture-to-fixture color uniformity, while the 25°–45° adjustable beam gives specifiers precise control over light distribution. Color temperature is warranted to shift no more than 200K over 5 years.

Electrical & Installation

Built for commercial flexibility, the ND22-20-4HRW operates on universal 120–277V input with a constant current Class A driver running at 167mA (120V) / 98mA (208V) / 84mA (240V) / 73mA (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 5 in cut-out.
