does anyone know if a reflector and condensor are needed for one of the ushio bulbs and a 15" screen?

ok, thanks...
i had a core/coil ballast and one of the huge globe bulbs and was having problems with an even light and such, i just got an electronic ballast for cheap and ordered a ushio bulb, so i'm going to work on a newer nicer enclosure with this new setup

Are you sure a reflector's needed? I mean, I've heard most reflectors only add about 30% more brightness. I've also heard the ushio is plenty bright without. But for all I know, you're right. Just asking.

so far no matter what bulb yer useing you can always use more light .... so 30% is alot
