All light bulbs use energy.
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
So the ones which use the most energy are called incandescent and then halogen.
