Performance & Light Output

High-voltage (VD) models deliver more lumens and higher LPW than their UD equivalents at identical wattage due to improved driver efficiency at higher input voltage. The 5000K CCT also yields slightly more lumens than 4000K at same wattage. Peak efficacy: 179 LPW (SIG/450W/750/VD, order code 12348). Peak output: 104,460 lm / 174 LPW (SIG/600W/750/VD, order code 12358). Optional distribution accessories affect output: PC30D lens (0.97), PC60D lens (0.98), AL90D reflector (0.95).

Smart & Control Features

Z10 Receptacle (ANSI C136.41) standard on all models — simplifies integration with photocells, occupancy sensors, and smart lighting networks without field wiring into the fixture housing. 0–10V continuous dimming standard.

Electrical

UD models: 120–277V AC, 60 Hz. VD models: 277–480V AC, 60 Hz. Both: 0–10V dimming | PF: >0.9 | THD: <20% | 10kV driver + 20kV supplemental surge protection to ANSI standards. VD models eliminate step-down transformers in three-phase 480V systems. RoHS compliant.
