Haitz’s Law – Moore’s Law for LEDs

Haitz’s Law is an observation/prediction about the steady improvement over the years of light-emitting diodes – LEDs. It states that every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, the amount of light generated per LED package increases by a factor of 20, 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.
