For what it's worth, I emailed SunSpectra, who makes a ballast that potentially could work for the 945w CMH de bulb, to ask to point me toward anyone with growing experience with their ballast and that bulb combination.
My question...
"I'm in the market for a 945w DE CMH light and your 1000w LFSW ballast seems to be the only one on the market at this time that serves that bulb. Unfortunately I cannot find any grower input or experience with your ballast and that bulb combination. Can you point me toward anyone who has experience growing with this combo?"
Their answer...
"Sorry Micah, as far as I know the 945 lamp is still trial and error due to the connection of he 3 Ceramic filaments being unstable. So no, I apologize I do not."
