Hello !
If I recall correctly you've secured the make of enlarger bulbs when Philips stopped making them.
Very fine. And I bought some.
But I know a lot of people owning and using Durst enlarger in need of a 100 mm diameter bulb in the 250 to 300 W range to power the 60's and 70's enlargers like the 138, 139 and Laborator 1000.
Do you know if a short run of these bulb could be feasible which would make life for these beast far easier ?
Many thanks in advance for your research and answer !
