blue light hazard efficiency of radiation

ηB

quotient of blue light hazard weighted radiant flux and radiant flux

Note 1 to entry: The blue light hazard efficiency of radiation, ηB, is related to the blue light hazard efficacy of luminous radiation, KB,v, through ηB = KKB,v, where K is luminous efficacy of radiation, and to the blue light hazard factor of luminous radiation, αB,v, through ηB = VαB,v, where V is luminous efficiency of radiation.

Note 2 to entry: For some applications it might be necessary to state both, blue light hazard efficiency of radiation, ηB, and blue light hazard efficacy of luminous radiation, KB,v.

Note 3 to entry: The blue light hazard efficiency of radiation has unit one.
