The development of LED technology has resulted in steadily falling costs and ever increasing light outputs. Since the 1960, costs per lumen have fallen by a factor of 10 every decade and the
amount of light generated per LED package has increased by a factor of 20.

The exponential rise in light output, mirroring Moore’s Law for electronic devices, is called Haitz’s Law after Dr Roland Haitz.
