WebPhotometry is a system of language, mathematical formulations, and instrumental methodologies used to describe and measure the propagation of light through space and materials. In consequence, the radiation so studied is confined to the visible (VIS) portion of the spectrum. Only light is visible radiation. WebThe value of 683 lm/W is abbreviated as Km (the value of Km = 683 lm/W is given for photopic vision. For scotopic vision, K m ' = 1700 lm/W has to be used). However, a monochromatic light source emitting the same radiant power at 650 nm, where the human eye is far less sensitive and V (λ) = 0.107, has a luminous flux of 0.107 × 683 lm = 73.1 lm.
