I saw this video before, and I too had the same response as Bill. The only thing is that is only 1 300w vs a 1000w. You could put more plasmas, still have less wattage, but the same intensity.

The arugability factor comes in the amount of PAR and PPFD comparisons, of which I'm pretty sure those 1000 watters would destroy 2 plasmas.

I'd like to see some LEDs and a PAR comparison.
