I never thought I would see the day that my enlarger lamp would be too bright, b ut my Zone VI cold light is even with both supplemental diffusers under it , for cing me to stop down the lens into diffraction range.
I'm wondering if the Aristo solid state dimmer will work with my lamp. I'm tryin g to avoid ND filters.
I emailed Calumet a week ago with no response so far. Aristo's web site has it a nd it looks promising.
Yes the dimmer will work.You may want to run the Zone VIII developing time test. Cold lights give better results with denser negatives.

If you can find a used Zone VI Cold Light Stabilizer (discontinued) at a reasonable price, you can use it as a dimmer, even without hooking up the photocell (which normally has to installed separately for Aristo heads). If you turn down the lamp intensity by at least 25% you should get excellent stabilization as well with this unit.
Thanx. After pricing a filter holder and a couple of ND filters, there was no price difference to speak of and in the case of Kodak filters, the dimmer is actually cheaper (surprise).
The D750 Lamp Dimmer can be used with all Aristo Cold Light Enlarging Heads. It's available from B & H Photo ($89.95). At their web site go to PHOTO > ENLARGERS & ACCESSORIES > ACCESSORIES FOR COLD LIGHT HEADS.
The D750 dimmer has arrived and this is a follow up report.
Not only does it work as advertised, but has an unexpected benefit- the lamp has virtually no warm up period when I start an exposure! That means I can take the compensating tic-toc timer off and replace it with the old mechanical Gralab. One less wire to mess with. I wonder why this isn't mentioned in the product description?
Anybody wanna buy a Zone VI tic-toc timer? :-)
