The average light-emitting diode bulb outputs 83 lumens per watt, as of 2014. They also last 30 times longer than a comparable incandescent lamp. Rapid advancements in LED lighting technology led the U.S. Energy Information Administration to project an average light output by 2020 of 150 lumens per watt.
The average halogen incandescent lamp generates about 20 lumens per watt, and most compact fluorescent lights achieve an output of approximately 67 lumens per watt. Federal regulations requiring general service lighting to meet established energy efficiency standards have increased the research and development of LED lighting. The regulations, as well as state and local incentives, have increased the efficiency of lighting while providing long-term consumer savings.
