Citizen Chip-on-Board LEDs - Generation 2

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

  • Luminous flux and luminous efficacy has been improved by 15 to 33 % and 15 to 38 % respectively over those of the conventional models.
  • Generation 2 COBs inherit the same package sizes, shapes and electrical circuits of Generation 1, allowing direct replacement.
  • LED dice are placed to generate uniform light, allowing for optimum light distribution design of luminaires.
  • The product lineup covers a wide range of luminous flux.
  • The products have reduced variation in the chromaticity range and they are compliant with 3-step MacAdam ellipses.
  • We provide three 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.
