luminescence - light not due to incandescence; occurs at low temperatures. light, visible light, visible radiation - (physics) electromagnetic radiation that can produce a visual sensation; the light was filtered through a soft glass window.
Lumen is the SI unit of the luminous flux, which is a measure of the total amount of visible light emitted by a source. It is the perceived power of the light from a source.umen and Lux are two photometric units in the SI system of units.

These measurements are important in light sources and other cases where the intensity of the light plays a role.
