Got the plusrite 400 watt bulbs literally 10 minutes ago and plugged em in. So far so good. First impression is the 14k looks like a reflux 12k maybe a little brighter and the 20k is bright and a mix between radium colors and xm 20k. Burn in time will surely change them some so we shall see. still open to someone with a par meter getting some numbers on them. gotta go clean the glass to get a better look at them
