Optics

  • Light Output Options:
    • 2200 lumens (21W)
    • 3300 lumens (32W)
    • 4000 lumens (39W)
  • Emergency Output (BLF):
    • All variants - 180 Lumens
  • Available with 3000K and 4000K LED
  • Hexaprism inner tile optic for optimum diffusion, glare control and to enable an LG7 compliant space
  • Micro polymer optic outer tile for visual comfort and uniformity
  • Optional white louvre fitted in front of inner Hexaprism is available for alternative aesthetic
  • Light output distribution is 60% for the inner tile and 40% for the outer. For example the 4000 lumen product emits approx. 2400 lumens from the inner tile and 1600 lumens from the outer. The 3300 lumen product emits approx. 1980 lumens from the inner tile and 1320 lumens from the outer.
  • LED chips are densely distributed within the inner tile to achieve maximum output and efficiency
  • LED chips are spaced further apart within the outer tile for excellent uniformity, visual comfort and surface luminance
