The unit of luminous energy is the "lumen second" (lm·s). Luminous energy refers to the total amount of visible light emitted by a light source, taking into account the sensitivity of the human eye to different wavelengths of light. It is derived from the measurement of luminous flux (in lumens) over a period of time (in seconds).
