This weekend I have been looking for a LED light source and sent out a couple of emails and they were answered in less then 12 hours, wow. Mr. Richard Ross, RH Designs, was kind enough to direct me to Heiland Electronic who makes LED light sources for different enlarges. When asked if they had an English website, Mr. Jurgen Heiland responded by sending a pdf. Their LED light source is design to work with their Splitgrade controller, cost can arrange from 1679 Euros for a 4x5 to 2587 Euros for a 5x7, less if you have the Splitgrade controller.
