LED BULBS BEAT INCANDESCENTS IN LIFECYCLE ASSESSMENT
A comprehensive life cycle assessment study conducted by German lighting manufacturer, OSRAM, has found that the total energy used by an LED bulb from manufacture to disposal is only one fifth of that required by incandescent models. The study, "Life Cycle Assessment of Illuminants," details the energy required for raw material production, manufacturing and assembly, transport, use, and end-of-life management. Incandescent lamps were reported to use approximately 3,300 kWh during their entire life, compared to less than 670 kWh for LEDs. OSRAM expects that the market will shift in favor of LEDs in the coming years as developing technologies yield even greater efficiency throughout the product's entire life cycle.
