First question, I know dimming a 1000w se bulb isn't good because it changes the spectrum and efficiency but is the same true for 1000w de?
Second question, I notice that some ballasts are low frequency square wave, is that better?
Third question, CMH is supposed to be better than HPS, is this also true for HPS de? It seems that CMH 1000w de have less umol than HPS
