Energy efficient lighting refers to a lighting system that has a longer life and uses less energy, meaning that the user saves money. Artificial light sources are usually evaluated in terms of luminous efficacy of the source. This is the ratio between the luminous flux emitted by a device and the total input of power it consumes. The main difference between these two is that the latter accounts for any lost energy such as heat or anything that exits the device as something other than radiation. An energy saving bulb reduces this, has a longer life and uses less energy to power it, therefore saving the consumer money.
