5. Luminous efficacy - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficacy

   Luminous efficacy of radiation measures the fraction of electromagnetic power which is useful for lighting. It is obtained by dividing the luminous flux by the radiant flux . [ 4 ] Light wavelengths outside the visible spectrum reduce luminous efficacy, because they contribute to the radiant flux, while the luminous flux of such light is zero.

   Standard incandescent lamps have an efficacy of 10-17 lumens per watts and a lifetime of 750–2500 hours. Tungsten halogen lamps have an efficacy of 12-22 lumens per watts and a lifetime of 2000–4000 hours. Finally reflector lamps have an efficacy of 12-19 lumens per watts and a lifetime of 2000–3000 hours. [2]
