I know there was some discussion about using LEDs as a light source for enlarging some time ago. Just wondering if anyone is using such a source for monochrome printing, and, how they are getting on with it. I have a 5X4 enlarger (similar to a De Vere) with a digital closed loop colour system which is unfortunately no longer working. As I install a lot of LED lighting for a living I thought to rip out the guts of the head and replace with a suitable grid of white, blue and green Cree LEDs. It would be simple to set up a DMX controller for altering overall intensity and individual colour internsities to give grade control, or adjustment for different paper sensitivities.

Before commiting myself to the expense and work I would really like anyones views on the efficacy of LEDs. Any comments would be very gratefully received.
