LED Lights
What are lumens?
Lumen stands for luminous flux (also sometimes referred to as candlelight) and is an international standard for measuring the brightness of light. The lumen can be thought of casually as a measure of the total “amount” of visible light in some defined beam or angle, or emitted from some source. The number of candelas or lumens from a source also depends on its spectrum, via the nominal response of the human eye as represented in the luminosity function.
