michael_kadillak6 Posted January 31, 2003 Share Posted January 31, 2003 I wanted to know what users of the Durst 138 and 184 enlargers use as condensor light sources as I understand that the manufacturer of the original bulbs no longer produces them. Durst Pro USA offers a halogen replacement that requires head modification and is expensive and they also offer a digital head with a computer controller that is expensive times three. Is there a cost effective alternative that will produce enough power while at the same time be consistent across the negative area? Comments? I thank you for your assistance in advance.

gudmundur_ing_lfsson1 Posted January 31, 2003 Share Posted January 31, 2003 There is a person in Germany that might have a clue or a bulb foryour Durst 138/184 enlarger. Try to contact Wolfgang at FotoserviceWJungkunz@t-online.de. There are other solutions:a color head like the C 300 or my solution an Aristo VC cold light head + a Metrolux timer with a probe conecting the head and the timer. It is not quite the same as condensers but there is less print spotting. Just do not give up 8x10" for digital. Gudmundur Link to comment Share on other sites More sharing options...
kelly_flanigan1 Posted January 31, 2003 Share Posted January 31, 2003 There are three different types of light sources. One is a larger than 110mm Opal bulb; another is a dinky point light source; and another is the color head. Which is your question directed to?

ole_tjugen Posted February 1, 2003 Share Posted February 1, 2003 I walked into my local darkroom shop and bought a 300W opal bulb in December - and now you tell me I can't get one? ;) Link to comment Share on other sites More sharing options...
michael_mutmansky1 Posted February 1, 2003 Share Posted February 1, 2003 What is the lamp code on the Thorn lamp? I suspect that there are some available out there if you search the dark recesses of the camera stores and lamp warehouses. Otherwise, I think it would not be impossible to find another lamp that would work similarly. The european lamps are designed for 220-240 volt power, so that will not work without modification in your enlarger. You could get a step-up transformer for these, or put in a 220 vots service to use them. I'm thinking a cold light might be the way to go. ---Michael Link to comment Share on other sites More sharing options...
kelly_flanigan1 Posted February 1, 2003 Share Posted February 1, 2003 It looks like this thread is about the opal lamp type head. <BR><BR>The Durst 138S manual says the bulb should be at least 110mm diameter; for even illumination of 5x7. The lamp code word was OPAL; and they are in 200,300,500 watts; also the PROLA 500 projection lamp; others are Philips 375E 500 watt or the General Electric DMS PH/500TS. (info from the manual) .
