re: GrowLEDHydro 300W LED vs. 400W HID Demonstration
What say you?

I got a bitch to pitch: why do you call your Spectra LED 300 a 360?
Granted, light power comparisons are like apples v oranges but...
HIDs have parasitic power supplies too, but we still call them their bulb wattage size.
Spectra 300 is not twice the size of a 180, just twice the price.
And what's up with the funny math on their website?
E=IR and P=EI. E=volts, I=amperes, R=ohms, P=watts
Just because US primary education has become a pathetic world-stage laughing stock doesn't change the physics that I learned many moons ago.
The 180 ad copy is no better:
What's that, 137.5w? The big one draws 264w. Am I confused, or insulted?
Maybe I got out the wrong side of bed, and fell on my head
What say you?
