WebInformally, the power efficiency is also called “wall-plug efficiency.” The luminous flux measures the light power of a source as perceived by the human eye in units of lumen (lm). One lumen is defined as the luminous flux of a light source emitting an optical power of (1/683) watt at 555 nm. 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]
