Twenty-two percent of electricity in the U.S. is used for lighting. Ninety percent of the power used for a light bulb roduces heat rather than light. LEDs are over four times more efficient than traditional incandescent light bulbs.

Glass bulbs with filaments and tubes break — easily and often. Incandescent bulbs are the most inefficient lighting source. Compact fluorescent (CFL) bulbs are more efficient but still contain 5 milligrams of mercury, making them hazardous waste when they break or burn out.

LEDs offer the most efficient and environmentally clean — no mercury — lighting source. They are solid-state devices rather than glass tubes with filaments, which makes LEDs far more durable and long lasting. LEDs typically last 10-12 years, which significantly reduces maintenance costs and impact on landfills and the environment.
