Bob, we have all agreed that it doesent change the color of your corals.. it simplay tanks the look of the tank from but ugly to nice. 
the other situation is where people have been using 6500 PC bulbs and they switch to a radium MH. They think it is the color of the bulb that changes the coral over time so that it is colored even with the lights off, but it is realy the increase in PAR that the MH has over the PC that stimulates the coral to creat color pigments. of course there are other factors that help in this also (feeding, Alk, Ca, ect)
He didn't use the measurment LUX |
As far as I know Irradiance, and Lux is the same thing.(at least Tullock seems to feel they are)

so the important factor to the coral is the level of PAR not color, to the human it has to look good to. Some people like the 20K look, some the 10K look, some even the 6500K look so the actual color temp is all personal preference, which by the way what I have always said is "as long as you are supplying enuf PAR for the corals needs then the color is a personal choice."
