A unit of luminous flux represents the amount of light emitted that is visible to the human eye. In the International System of Units, it is the amount of light a one candela source emits over a square radian angle. It is used in measuring and comparing the amount of light visible to the human eye produced by lamps such as light-emitting diodes, co...
