So green LEDs do 235 lm/W and red LEDs in a reasonable mix do 150 lm/W (all theoretical limits) so the reds have to put out 1.5x the power to match. https://do

So green LEDs do 235 lm/W and red LEDs in a reasonable mix do 150 lm/W (all theoretical limits) so the reds have to put out 1.5x the power to match. https://donklipstein.com/led.html https://donklipstein.com/led.html (this website is pretty fantastic) The new limits are 120 lm/W. So it's going to be quite tough. Perhaps those 150 lm/W LEDs are not yet in commercial production. Definitely an interesting thing. I wonder what this means for things like the Phillips Hue line etc. Those have to be consuming way more power. https://www.energy.gov/articles/doe-finalizes-efficiency-standards-lightbulbs-save-americans-billions-household-energy#:~:text=Today's%20final%20rule%20will%20raise,and%20consumers%20are%20already%20embracing https://www.energy.gov/articles/doe-finalizes-efficiency-sta....
