I'm not talking about CFLs, which aren't new anymore. The U.S. Department of Energy is running a testing program for the next generation of energy efficient lighting, namely light-emitting diodes (LEDs), also known as solid-state lighting (SSL). DOE takes products that are available in the market now and puts them to the test to see if they really can do what they claim to.
This is important since into the future LEDs have great energy savings potential when compared not only to incandescent bulbs but also CFLs and other fluorescent technologies we now take for granted. CFLs have taken quite a while to work out some consumer satisfaction kinks and become mainstream. DOE is doing all it can to make sure LEDs and consumers don't have to experience the same growing pains in the marketplace.
Anyone can learn more about the program and see the test results for many LED/SSL products at the CALiPER website.
