The now notorious ban of incandescent light bulbs, mandated by the Energy Independence and Security Act of 2007, is about to make 100-watt traditional incandescent bulbs a thing of the past with the ban taking effect beginning January 1, 2012.
Ironically, it was on December 31, 1879 that inventor Thomas Edison gave the first public demonstration of his revolutionary incandescent bulb.
Importantly, Edison wasn’t the first inventor to work on such a lamp. British chemist and inventor Humphrey Davy demonstrated the principle of incandescent lamps as early as 1802 by passing a current through a strip of platinum. But while this set the stage for future development, the Davy lamp was expensive, produced only weak light for a short time, and was not practical.
