72,000 lumen LED flashlight


The lumen is the International System of Units derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model of the human eye’s sensitivity to various wavelengths. Lumens are related to lux in that one lux is one lumen per square meter. [Via: wikipedia]
