Technical Specs

  • LED Boards: FR4 PCB is used to limit stress on solder joints by matching coefficient of thermal expansion between the LED and the PCB more closely.
  • Power Supply Access: Easy access from the top of the fixture.
  • Power Input: 120-277V (50/60Hz).
  • Power Factor: Greater than 0.9 (0.96–0.99 typical).
  • Total Harmonic Distortion: Less than 20%, 10% typical.
  • Surge Protection: Standard is 6kV for drivers. Additional surge protection is available. All HV orders will have 10kV SRG automatically added (contact sales for questions).
  • Emergency Battery Backup (EMB): Initial lumen output is 2200- 2400 lumens, thereafter EMB produces 1900-2000 lumens for a minimum of 90 minutes. 16 watts initial output. Temperature range 0°C to 45°C.
  • Environment: Dry/Damp, for interior applications (IP4X). Non IC rated.
  • Ambient Range Operation: -40°C up to 45°C (-40°F up to 113°F).
  • CCT: 3500K, 4000K and 5000K standard, other CCT available (extended lead time).
