On September 24, 2009 the DOE announced that Philips Lighting North America was the first to submit lamps in the category to replace the standard 60 W A-19 "Edison screw fixture" light bulb, with a design based on their earlier "EnduraLED" consumer product.
On August 3, 2011, DOE awarded the prize in the 60 W replacement category to Philips bulb after 18 months of extensive testing. The 10-W, 900-lumen Philips bulb was made available to consumers in April 2012.
The same day, CREE demonstrated a prototype lamp producing 1330 lumens with a mere 8.7 W of input power. While the CREE lamp has not undergone DOE reliability testing and no commercial release date was promised, it is an indication that the "21st Century Lamp" performance levels may soon be within reach of commercial products.
Highly efficient LED Bulb Driver - Infineon
The highly efficient dimmable LED driver system utilizing ICL8001G sets a new Benchmark with respect to integration, performance, features and total system cost. ICL8001G employs quasi-resonant operation modes with integrated power factor control for off-line residential LED lighting applications in particular 40W / 60W / 100W incandescent bulb replacements.
