It MAY be possible to do azo enlarging with led's. Led's are made by Cree research here in Raleigh, and they put us onto a lamp manufacturer that I have some response from. The plan was to see if led's would work and cheaper than the head M&P were handling for $1900.00.
I have not had time to work on this, hopefully by spring we will know the possibilities.
I will post when I actually know something. Right now it is embryonic.
