L'efficacité lumineuse d'une lampe est la quantité de lumière émise par nombre de watts consommés. Elle s'exprime en lumens/watt (lm/W) et permet de comparer les lampes entre elles. Plus cette efficacité est grande et plus la lampe émet de la lumière pour une même consommation d'électricité. L'efficacité des lampes à incandescence se situe entre 12 lm/W et 20 lm/W alors qu'elle est comprise entre 40 lm/W et 100 lm/W pour les lampes fluorescentes. 3, record 1, French, - efficacit%C3%A9%20lumineuse
