I was shopping at Lowes today for some CF's and I came across some HPS bulbs. The 400w bulbs Male part was huge and I knew I would need a ballest. But couldnt find one. BUT..... the lower wattage ones would be able to fit into my regular sockets. Now the question is can I use these without installing a special fixture and just take out my CFL and use a 100w HPS and MH light.
