Haitz's Law

Haitz's Law

Haitz's Law states that every decade, the price of LEDs have fallen by 10x while the performance (measured in flux per unit) has increased by 20x, for a given wavelength (color) of light. It is considered the LED counterpart to Moore's Law, which states that the number of transistors in a given integrated circuit doubles every 18 to 24 months.

Haitz's Law is named after Dr. Roland Haitz, a now-retired scientist at Agilent Technologies.
