Citizen Chip-on-Board LEDs - Generation 4

Applications include: halogen and mini halogen replacements, LED bulbs, down lights, high bay, flood lights, street lights.

  • Luminous efficacy improved by about 15% over Generation 3, again achieving the world's highest at launch
  • Color rendering is improved while high efficacy is retained
  • 3 types of high color rendering products pursuing quality of light: "Ra 90 on B.B.L.*" "Ra 90 below B.B.L.*" and "Ra 97."
    * B.B.L.: stands for Black Body Locus.
  • UL standard (UL 8750) certification
  • Same package sizes and shapes as Generation 3, allowing for direct replacement
  • LED dice are placed to generate uniform light, allowing for optimum light distribution design of luminaires
  • Wide range of luminous flux options
  • Reduced variation in chromaticity range; compliant with 3-step MacAdam ellipses.
