Luminous efficacy is an index of how bright a light source can be with a certain electricity. The maximum possible luminous efficacy is 683 lm/W [lumen per watt] due to conservation of energy. Although incandescent lights make a great atmosphere in a house, the luminous efficacy is only 10 – 20 lm/W. LED and fluorescent lights have 60 – 80 lm/W.
