To be honest, if I were you I would not get those projectors. I had Angeleyes that looked just like that, I could almost swear they were the same ones, and I had a horrible time with them. 3 of the 4 halos burned out, they were a pain to adjust, light output from them was horrible. and one of them filled up with water and would fog up.
If I were you I would go for a set of TYC's they are not Halos, but the light output on them is far better, they are solid, and they come adjusted almost if not perfect (mine didn't even need adjustment!) plus, the bulbs on them are a lot easier to change since they dont have retarded rubber caps like the Halos.
Also a sidenote, I personally think they look loads better too
Heres a link of the ones that are identical to the ones I bought, plus they are cheaper!
