i am going to build a 7" lilliput PJ and need help with the bulb and ballast, what should i get? i think im going to go for a double ended 150w metal halide but which one? and which ballast will go with it?

also i would really like to do an LED setup, so if anyone can direct me to a place that sells LED arrays for a 7" LCD i will defo go for that over the MH bulb. its going to be used mostly in a dark room anyway and the PJ is going to have a very short FL so hopefully i wont lose too much light

Thanks
