I have a couple of Norman RDP-5 reflectors which have a white interior and white glass dome over the reflector. It gives a softer light and has a 140 degree light spread. You have a -2 stop light loss so you have to boost up power. In regards to above post, Lumedyne does make some packs that have variable power settings from 200 ws. down to 3 ws. I have had one of my packs which is a basic 200-100-50 ws modified by Lumedyne to do go down to 3 ws. So if this is what you need you can always buy an older pack and have it modified.
