• Luminaire consists of:
  • White ra90 LEDs emitting 11,500 lumens (134W)
  • Green LEDs emitting 1400 lumens (65W)
• Two TP(a) rated optic options:
  • Prismatic acrylic above 4mm toughened glass
  • Single sheet 3mm prismatic fireguard material
• Emergency Output (BLF):
  • All variants - 280 Lumens
• White Ra>90 LEDS with 4000K ‘cool’ white colour temperature
• Green LEDs at wavelength of 505nm
• Separate switching of white and green LEDs
