I'd like to build a cold light head for my Omega D2.

I understand that the light source in the Omega "Omegalite" is an ordinary house hold circular fluorescent light tube. I presume that there is a frosted or opal glass diffusion plate in the Omegalite as well.

A couple of questions if I may.

1) Has anyone built their own cold light source? What did you use and what was t he internal construction that you found to be sucessful? The Aristo units seem to be little more than a tightly coiled lamp tube mounted quite close tot he dif fusion plate.

2) For anyone who uses an Omegalite, what is inside the housing besides the fluo rescent tube and diffusion plate? The external shape of the Omeglite suggests t hat domed top might be coated with white material internally to serve as a form of integrating sphere to level the light distribution. It would seem to be simpl e to improvise from a metal kitchen bowl painted with plat white paint.

Thanks in advance.
