Cree LightingIt is easy being green. Cree lighting uses 85% less energy than conventional incandescent bulbs and less than half the energy of compact fluorescent lamps. Consuming less energy results in fewer greenhouse gas emissions being released into our environment.Also, because each Cree lighting is designed to last for 50,000 or more hours, there is less landfill waste from burned-out incandescent bulbs and no dangerous mercury waste from fluorescents. With Cree Lighting, there is no compromise. You can have safe, affordable, beautiful lighting that makes a positive difference.
