The ballast factor is not constant it varies with the lamps. Probably
from something like .60 when underdriving VHOs and 2.2 when overdriving
NO lamps. This is a critical piece of info if you want to know what you
are getting. I think it is a little bit of dirty pool for Icecap to not
explain this in their marketing. It kind of mystifies me that they take
this approach as I think they have a good product.
