Is this conversion thing really expensive? And it is wired for 270 not 400 but i will switch that depending on the amount of pants.. Good idea, bad idea?
They are much cheaper than buying two seprate lights. But if u already have an MH there is no point in purchasing a conversion hps mh. Un less u want to run two lights at the same time.
What does this mean? Sounds like your talking about a multi-tap ballast that can be wired for different input voltages. I say that because I've never heard of a ballast than can be wired differently to adapt to different wattages.
