Bulbs for Durst 138 in Europe

[andreios]

Hello folks,

I have been trying to get to know my new-to-me Durst 138. I realized, that the current bulb that I have - 300W, diameter of 90mm is most likely not sufficient to illumine fully the 13x18cm negative. The previous owner used it only up to 4x5 where this is not a problem. I've read the manual and it says that for enlarging 13x18cm negatives (with 210mm lens and two 240 condensers) one should use a bulb with diameter of 110mm.
Now, my question is - where should I get one? I have been looking around both locally and on the internet, I have found some threads but those were only concerned with US market. What should I search for? Any ideas?
Or could a solution be to put some sort of diffuser in the light path between the bulb and the condensers?

Any advice would be most welcome.

Thanks in advance

Try www.proflamps.com - They stock several Dead Link Removed lamps from 75W up to 250W, so they should be able to supply one to suit your needs.

Paul, thanks for the links! The photocrescenta lamps may have enough wattage, but they are even smaller than the ones that I have now. I will read through the LED options, there is a LED specialist retail near to my work so I may try something out in near future..

There was a post on LFF about a homemade diffuser head for 5x7 and 8x10 enlargers - or rather the adapter was homemade and the lightsource was off-the-shelf. It seems a very quick and simple adaptation, if a condenser light-source is not critical for you. I also recall reading of several adaptations using commercial LED downlighting units, mounted in place of the wide bulb and retaining the condensers, but those are less quickly reversed and need far more hand work.

Sorry, my mistake entirely - I had been looking at the Over All Length and missed the Diameter completely...
