Are LEDs more efficient than fluorescent light sources?
Not yet. A compact fluorescent light source (CFL) produces about 50 lumens/watt. So, LEDs presently have an efficacy (efficiency rating) that is somewhere between incandescent and fluorescent light sources. Having made this statement of course LED’s are more Eco frindly as no mercury is used in their manufacture and signficantly less energy is used at the manufacturing source to make them.
