Web1.10 Luminous efficacy of lamps. Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power. Depending on the context, the power can be either the radiant flux of the source’s output, or the total electric power consumed by the source. Lamps convert electrical energy into light. WebA source radiating a power of one watt of light in the color for which the eye is most efficient (a wavelength of 555 nm, in the green region of the optical spectrum) has luminous flux of 683 lumens. So a lumen represents at least 1/683 watts of visible light power, depending on the spectral distribution. Lighting [ edit] the owd betts
