Interesting story RyanF40T12, I almost never run into VHO in the field anymore, in fact im pretty sure the last VHO installation ive seen was nearly 5 years ago and it was the 220w 8-footers. I think ive seen only one F40T12VHO installation ever, and that was in a public museum. The ban of magnetic T12 ballasts was probably the last nail in the coffin for VHO, as the only electronic VHO ballasts ive seen so far are for the aquarium trade, nothing exists in commercial lighting now that's specifically rated for VHO T12
