on the end bulbs, always was a fan of the vert bulb in a parabolic hood. i just wish they made a de bulb that can burn vert.
u ever mess with the philips single ended cmh/cmd 860w ?
no, never have. im using cheap digital ballasts that i got from a storage unit auction. got 20 ballasts and 20 something light movers. sold all the light movers, made my money back and then some, and then kept the ballasts to use.
they arent dimmable and my guess is that they arent the most efficient.
is there any reason why DE bulbs cant be burned vertically or is it just a lack of reflector options? my buddy is quite the fabricator so if it can be done we could do it
