A 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] See more The lumen (symbol: lm) is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units (SI). Luminous flux differs from power See more If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted … See more ANSI lumens The light output of projectors (including video projectors) is typically measured in lumens.
