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.
