Ha................you wanna start this again????
.........lol
So as I said above ^^^we are on EARTH, so light efficiency aside 600watts hid ==== 600watts led=== 600w cfls====600w t5/t8/t12/pll/etc=====600w Induction====so on and so on
AMPS x VOLTS ====== WATTS............. watt====watt..............for the 35th time
1 watt = 1 joule/sec ...............and/or............................. 1 joule = 1 watt/sec
ONE joule is the energy required to heat one gram dry/cool air by 1 degree celcius this shit will never change brother no matter how you spin it. we aren't ignoring physics or the laws of thermodynamics are we???
"energy cannot be created or destroyed"
600 watts(ballast is another 50w) coming out of a ten inch bulb(hps) will FEEL hotter than 600watts of leds spread out over a 3x3 panel (fero 600watt)=====but will raise the ambient room temps exactly the same if they draw the same from the plug.
FACT.......
