I recently was given 9 advance ballast IZT-3S32-SC. These are dimming
ballasts for 2 lamps. Can they be used with just two lamps like some where
you just don't use one of the wires? Also, I have googled and cannot figure
out if the purple and grey wire have to have voltage on them to fire the
lamps or not. I think from what I have read, that to get 100% output, you
have to put 10V dc on them but I am not sure. If this is true, where do you
get the 10V? Anyone have any experience with them?
Here is a link to the Spec Sheet
