  2. Luminous efficacy - Wikipedia

    en.wikipedia.org/wiki/Luminous_efficacy

    The main difference between the luminous efficacy of radiation and the luminous efficacy of a source is that the latter accounts for input energy that is lost as heat or otherwise exits the source as something other than electromagnetic radiation. Luminous efficacy of radiation is a property of the radiation emitted by a source. Luminous ...
