Is lumen the same as spectrum
WitrynaLumen is often used to indicate the brightness of light sources. While lumen is a unit used to express the total amount of light from a source, lux is the total amount of light from a source incident on a particular surface area. One lux is equal to one lumen of the light incident per square meter.
