Making the switch to LED lighting can improve energy efficiency in buildings.
Incandescent bulbs and metal-halide lighting fixtures are often the best candidates for replacement with LED lighting fixtures because they are higher in wattage, less energy efficient, and therefore provide a quicker return on investment. LEDs often pay for themselves within five years. LED bulbs can also generally last 25,000 hours or more before needing replacement, meaning that maintenance and labor costs are often less for those bulbs and fixtures. Consumers can purchase LED light bulbs at their local hardware store, and some retailers may provide point-of-sale rebates from ComEd.
