Can you stay with cfl's? I'm a little leery of a hid in there. But that's the grandpa coming out it me. It does that every once and a while.
I'm sure it can be done. What would you think of a 250 hps. Now do you know you have to have a ballast. You also will need some way of attaching the bulb socket holder to the plastic. I'm not liking this as I explaining it to you.
I guess it can be done. But I sure would not do it. Good luck man. I'm sure you have a good reason, I hope.
