Sorry, you lost me there, that has nothing to do with Haitz's law, but in context:
"The [2000] publication also forecast that the
efficacy of LED-based lighting could reach 200 lm/W (
lumen per Watt) in 2020, crossing 100 lm/W in 2010. This would be the case if enough industrial and government resources were spent for research on LED-lighting. More than 50% of the electricity consumption for lighting (20% of the totally consumed electrical energy) would be saved reaching 200 lm/W. This prospect and other stepping-stone applications of LEDs (e.g. mobile phone flash and LCD-backlighting) led to a massive investment in LED-research so that the LED efficacy did indeed cross 100 lm/W in 2010."
He just encouraged more research in 2000, and he was fucking right. Actually forget 2020, there are 200lm/W* growers in this forum.
* Supposedly. No actual testing has proven this quite yet. We need a light maker to pony up the $2-300 to actually test their lights. Ahem.
@Stephenj37826? What happened with the planned integrating sphere testing?
