Light sources emit energy in the form of electromagnetic waves which spread out in all directions. The amount of energy radiated during a unit of time (the power) may be expressed in physical units as ergs per second, or in watts. Apart from the total energy, we may also consider the amount of energy passing through a certain part of a plane, or within a certain solid angle, and express this in the same units.
