WebThe lumen is the photometric equivalent of the watt, weighted to match the eye response of the standard observer. (1 watt at 555 nm=683.0 lumens) How are Lumens measured? A lumen is measured by a square meter or lux. 1 watt corresponds to approximately 10 lumens. The measure of photometric power. Illuminance (Lux) (E or lm/m^2) = Density of ...
