I would be interested in your findings as Ontario has passed a law which in effect stops the use of the tungston light bulb in 2010.
This makes me nervous as I have invested heavily in traditional enlargers which all use tungston bulbs. I have no intention of getting rid of the gear and short of stockpiling a lifetime of bulbs, I would like to know my options.
I use the Omegas, Durst, and Deveere ... philips 250w, ELC's ELH's
Besides costs , were they of any practical use to be modified to the current enlargers?
I spent a lot of time with manufacturers, one with the module shown, and they couldn't advise the use of these for an enlarger light source. There were so many reasons I couldn't list them here. I came to the conclusion that the expensive LED heads are expensive for a reason.
