Ultra-Efficient LEDs developed by MIT

No new information, but I did read the paper.

Don't hold your breath waiting for the "miracle lights".
We don't exceed unity until we get a narrow gap device down to 30 picowatts.

Hmmm, lemme whip out my slide rule.
<mumble, carry the P, transpose, mumble>
Lessee now, if I wire up 33 million emitters, I'll have a very efficient one watt array.

Sigh!
Next!

Aloha,
Weeze

Thanks for giving us some perspective! I have no idea how to do the math, but until we are printing sheets of LEDs like this, I doubt we'll see anything come to market in the grow sector.
I knew it must be too good to be true.
