LED life-cycle assessment

LED life-cycle assessment
Source: OSRAM GmbH
Light Emitting Diodes are among the most energy-efficient light sources available on the market. LED lamps are already today more than five times more efficient than incandescent lamps and future technical achievements offer additional potential for the coming years.
At present, artificial lighting accounts for around 19% of global electricity consumption – that corresponds to 2.4% of worldwide primary energy consumption. 70% of the energy used for artificial lighting is consumed by lamps for which there are more energy-efficient alternatives. Simply replacing conventional light sources with LEDs would theoretically halve global electricity consumption for lighting. The potential savings are therefore enormous.
An OSRAM study monitored the life cycle of an LED and an LED lamp. It´s outcome made it clear – LED lamps need less than 2% of their energy consumption for their manufacture – over 98% are used for their task: illuminating the world.
