Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Despite using less energy they emit almost the same amount of lumens.
Examples of energy saving lamps include:
Fluorescent lamps; i.e. regular and compact LED lamp a Light-emitting electrochemical cell Magnetic induction lamps
