    Looks like the 220V 2000W lamp. If this was a Durst-Pro 2000W conversion, then I suspect it is probably done well. Again, all my dealings with Durst-Pro were favorable, and Jens was helpful and knowledgeable whenever I contacted him.

    I don't know what that brown is at the base of the lamp. I'd probably get a new lamp.

    If found the most "on time" for my lamp was during composing and cropping. So, I have created tables for all my popular enlargements with easel markings, head and baseboard height and focal length lens. So, I can set up the enlarger head and baseboard based on the centimeter scales before I even turn the lamp on.

    You might be the first person on this forum whom Jens didn't burn at some point or another. I know it's disrespectful to speak ill of the dead, and that's not my point anyway. He was an excellent machinist and cerrtainly knew what he was doing with Durst, but one was lucky to get complete delivery unless they paid an awful lot up front, and signed an expensive long-term service contract, which is what he was really after. Ironically, I got one of his big Durst enlargers for free second-hand; but the original owner paid dearly for it. So that slightly makes up for the 4K of gear he still owed me before he passed.

    IC, is it possible for Michael to use a 1000W lamp? I believe replacements may be easier to find than the 2000W lamp?

    I met Jens at the first Large Format View Camera Conference in Albuquerque New Mexico in 1999 and eventually I got into a squabble with him 10 years ago over some supposed under billing for some items. We worked it our fortunately. My son was considering going to Portland State five years ago and when we made a trip over to see their shop and we had lunch with Jens. Things seemed to be going OK for him and then shortly he was gone. I have no idea whatever happened to all of the equipment they had at their shop.

    Was about to ask that question myself. Luis. I also need to find a place to find a spare bulb based upon the discoloring of the existing bulb have. Maybe the folks that sell these bulbs can validate the wattage of the existing bulb I have?

    If the EST2000-N is putting out the 220V that it normally would, then the 120V 1000W lamp will fry!

    I'd just use the setup you have now and try to get a spare 220V 2000w lamp. There is one on ebay now.

    In a post-apocolyptic situation, one could just wire 120V from the wall socket up to the 1000W lamp and turn it on-and-off with an appropriate rated 1000W timer or a relay/contactor. Just leave the CLS1840 shutter open and use the external fan. In that situation you would not need any power supply.

    You have the 2000W 220V lamp like this one that is currently for sale:

    Again, knowing Jens put your system together makes me feel more comfortable about seeing the CLS1840 mated to an EST2000-N. I had initially thought you just got a hodge-podge assembly of components that won't work together.

    Here is an advertisement from an old Durst-Pro document. It has very little information about your setup, only that it confirms it was available through Durst-Pro.

    It reads:

    "Upgrade kit, for [CLS1840 to] 2000 watt lamp operation"

    this last document clearly states that the CLS 1840 will not work with the Nega carriers. Quite the opposite I was reading some pages back. Only way to know is probably find someone with such head and sending him my carrier to test. Confused by Durst literature.

    the only picture I have found is a unit a broker is selling, which shows what seems a Nega carrier under a CLS 2000
