The only manufacturer I know that's still making cold light heads is
Aristo (http://www.aristogrid.com/cold_light_chart.html). They're sure
to have one that will satisfy your needs.

And a word of advice: whichever one you get, get the light tube balanced
for variable contrast paper. V54, I think. The VC tube will work with
both VC and Graded types of paper. There's even a tube balanced for
color papers, but if you intend to do color, too, I would recommend that
you just get an Omega color head. It will work just fine with b&w and
it's a diffusion type head just like most cold light heads.
