Re: pretty unbelievable

They are full of it. 3.9 PPF/W would be possible for red monos if they were at the same efficiency levels as the best royal blue LEDs. The best royal blue LEDs currently have around 75% radiant efficiency, while the best deep red LEDs have around 55% efficiency. A 660nm mono with 71% efficiency woul...
