When Will We Switch From Light Bulbs to LEDs?
The holiday season is coming, and you've probably already bought some lights and decorations for your Christmas tree, your house or even your street. But did you know that the market for light bulbs is a $12 to $15 billion one? Now, several companies making light-emitting diodes (LEDs) want a piece of this market, claiming that LEDs are more efficient than light bulbs and could save a staggering $17 billion a year in energy costs.

In "Switching off bulbs for LEDs," the San Jose Mercury News reports that in ten years, you'll go to your Wal-Mart store to buy LEDs instead of light bulbs, thanks to fantastic improvements in performance by the LED industry.

And did you know that each decade since the first LED appeared in 1962, prices have fallen by a factor of 10 while performance has grown by a factor of 20? In the world of LED engineers, this is known as Haitz's Law, named after retired Agilent scientist Roland Haitz. You'll find pictures and other references in this overview.
