Zone VI LED 4x5 VC Head?

[Neil Poulsen]

Has anyone used the Zone VI LED variable contrast enlarger head? If so, are they as consistent as Calumet suggests? Are they bright enough for 35mm or medium format?

What are your experiences in using one of these heads?

Alan Ross did a favorable review for View Camera Magazine more than one year ago. I have asked about this head on APUG before and did not get much feedback. Calumet told me that they intended to make the head adaptable to other enlargers but that has not happened as far as I know. There are several APUG threads about DIY LED light sources including one currently.
