Cree, Inc. announced last week that they developed a white power LED that produces 208 lumens of light per watt. Why is this record-breaking? Single white power LEDs were thought to be limited to 200 lumens per watt efficacy prior to this development. To help put this into context, standard fluorescent lights can only produce 100 lumens of light per watt at the very most. So, this new Cree LED product produces twice the amount of light possible for fluorescents. By the way, conventional 60-100 watt incandescent light bulbs produce just 15 lumens of light per watt.
Cree clearly continues to develop LED lighting products that will start to render incandescent light bulbs obsolete in the near future, helping to push the market toward more environmentally-friendly lighting. This announcement signifies that LED performance will continue to improve past industry expectations with further research and development. While this product is not yet available on the market, lab-level LEDs from Cree in the past have taken only twelve months to be commercialized.
