LLHP is a long-life high-efficiency LED high bay product that meets the most restrictive lighting power density codes and typically qualifies for utility rebate programs. The LLHP uses individual specialized optics for each LED designed to provide precise control of light from the point source to the work plane. Three distribution choices ensure that each LED operates optimally and distributes the light where it's needed, whether for aisles or open areas.

  • Highly efficient LEDs provide up to 101 lumens per watt at 70 CRI
  • Long-life, 60,000 hour LEDs at L90 reduce life cycle maintenance costs
  • 2' size provides nominal lumen packages from 12,000 to 27,000
  • 3' size provides nominal lumen packages from 37,850 to 42,100
  • Three distribution selections: aisle, medium, and wide
  • Operates in ambient temperatures from 55˚C/131˚F down to 40˚C/40˚F (0˚C/32˚F with Occupancy Sensor)
  • Individual optics for each LED allow for precise control of light distribution
  • Extruded aluminum housing acts as heat sink
  • Downward sloping fins minimize debris buildup
  • Fixed output or 0-10V dimming available
  • Product designed for quick and easy suspension mounting with aircraft cabling
  • CSA listed and suitable for damp locations
