Ok, let's hear it!

I realize that he does supplement with purple T5s to bring the red spectrum back in, but all the high end LEDs fixtures supplement by adding "full spectrum" LEDs nowadays. In theory it should be the same thing?

full spectrum means the same thing in LED and older tech? ya think?

I dunno, I would have assumed so. If you read the LED manufacturer's literature they show a spectral graph usually. The full spectrum units tend to have the "full" spread across the spectrum. Then the user is free to play with the amount of spectrum they want to throw out by infinitely adjusting each LED. At least that was my impression of how "full spectrum" LED units worked. I say we ask Steve. He'll know.

as far as i know LED have sharp spikes (each type of LED present) in those plots and manufacturer's just connect the dots and make those pretty graphs to more closely match LED output to that of halides.

I think it's the same for everything, the equipment only measures peak output at certain spectrum then they plot best fit curves. You're right about LEDs and the narrow spectrum for colored LEDs but the white LEDs have broad spectrum curves so it's hard to say what the real curves look like vs other lights.
