Heiland Cold Light source.


I have the last ones, after Calumet bought out Zone VI. 8x10, 5x7 and a 4x5. These are quite good.
I have Beseler 45 Universal heads as well, RGB dichro, color or VCCE controllers, these can act up, the cold lights work great. I believe that the last of the Z6 heads were made by Aristo, not sure of the specifics, plenty bright. I mostly use the 5x7 (6x17).

The enlargers are the type 2, have very little use.
 

Otto - which Beseler enlarger are you using with the Heiland? I have the Beseler 23Ciii-XL with the VC head and I'm unsure how the Heiland LED lamp attaches to or replaces the VC head. I think it's meant to be a replacement light sources on the condenser head, but since I do not have access to this lamphouse I'm unable to verify if it would resolve my light mounting issue.
 

Can't say about the Beseler, but with my Omega D5 the Heiland replaces the entire condenser and lamphouse, sitting right on top of the negative stage. Also, to Otto's comment about lengthened development times--this should not be. Paper should be developed to completion, no matter what the light source is. Unless you're making litho prints.
 

I’ve got the 45MX or how they call it, for 4x5 and smaller in any case. I bought it with the Aristo cold light head and don’t have the original Beseler condenser. When the condensor is replaced the whole light house goes with it. You have to specify to Heiland which enlarger you have before ordering. I doubt whether the 23 has the same size for a light head as the 45. Heiland has different sizes of the LED head for different brands enlargers.
 
I don't want to start a new thread, so I'll try to revive this one.
I have the opportunity to buy a used Heiland LED Head. Unfortunately, it's far from me and it's an estate sale, so the seller doesn't know any technical details.
I tried writing an email to Heiland, but no response yet.

From what I understand, they use a large number of LEDs, which will not be very powerful. Around 1600 for a 5x7 unit, 24V powersupply (which looks like the one for the laptop). I would be mainly interested in specs of LEDs - power and wavelength of each color. I expect that they will be LEDs of individual colors and not some addressable RGB solution.



Does anyone have more detailed information? I couldn't find anything on the internet.
Thanks.
 

Have you tried contacting Heiland?
 
Okay, I'll try contacting CatLabs.

That's a safe assumption.

Are you intending to do color work with it?

I was surprised that they use such a large number of small LEDs. Addressable RGB LEDs as far as I know are used by Ilford in their LED source.

I primarily do B&W, but I would like to try RA4 as well. If it is possible of course. The Ilford solution is not suitable, from what I have seen.

There are a lot of people here at Photrio who make their own LED heads and controllers, but I'd rather avoid that. Soldering, power supplies, PWM, microcontrollers....that's been beyond me so far.
 
I know people who have printed color with the Heiland heads. As far as I can tell they've been able to make perfectly fine color prints that way. That's about all I can say; I've not tried these heads myself and I don't know much about the technical details. I do know there are several versions of the Heiland heads and they use different kinds of LEDs.
