  1. So I just need to know if I buy a 400w mh/hps ballast ( both bulbs included) that both bulbs are workable with the same ballast?

  2. if it says on the ballast that it will run both, your good to go
  3. If it is a digital ballast, yes, you are good to go! I don't believe a magnetic ballast will do both. If it came with both, you should be good to go! Hmmmm...did I just cancel my comment? Ha! Digital works for both!!!! :smoke:
  4. They'll both work with either a digital or magnetic ballast. When you get replacements just make sure that they are not 400v.
