It looks exactly the same as ic-racer's in post #887

So, I reopened my CLS 2000 head, in order to take some pictures of the IR filter in position 32.

As you can see, this filter is actually part of the light bulb /...

ic-racer,

I know the feeling…
When I had the head open back in January, I only took pictures of the dichroic filters…
That's why I haven't posted a picture of the filter in question from my own...

esearing,

Thankfully I never had any issues with the controllers.

The original one that came with my enlarger in 2007 was working fine when I switched to the Analyser 500 about 12 years ago.
...

ic-racer,

I won't get into the "why" I had to open the head that far just yet, in order to avoid muddy the waters with information unrelated to the question at hand… once I'm done fixing the...

In the CLS 2000 manual there are two separate references of 2 Infra-Red absorbing filters between the lamp/dichroic-reflector assembly and the color Dichroic filters:

The closest I can...

Hi Gary,

Thank you so much for jumping in, I just saved your pics and measurements in my reference folder…

The filter in your picture is the #33 in the diagram in post #877 just above, which is...

Relating to my above question about the IR filter(s) in the CLS 2000 head:

I'm currently talking (email) with Kienzle in Germany about the possibility of buying replacement dichroic and IR filters...

A long overdue update:

About a week after my last post, the fan died.

I kept using the enlarger without a fan for a while, constantly monitoring the head's temperature.
Since I almost...

Question:

According to the manual, there are 2 IR filters between the halogen lamp and the dichroic filters…

In my head, there is only one…

Could anyone check and let me know if theirs has...

Does anyone know of a source for dichroic filters for the CLS 2000 head?

A preliminary search shows that most places top out at 50mm square, which is too small.

Specifically, I need to replace...

Thanks Gary,
That's very helpful.
The breaker for the wall outlets in my darkroom is 40A, but all my cables from the wall outlets towards any device which is not close to a wall are 13A.
The short...

Thank you ic-racer.
Not ready yet to attempt actual printing, since there are still many things that need fixing…
I'm taking it a step at a time…
Safety first…

The CLS2000 manual doesn't give any specs for timer suitability.

Is my 220v digital timer with "switching capacity: 1000va" and an "T4amp " safe to use?

(also, separate question):

You could also sandwich 2 step wedges together (if you have a spare one) as a calibration tool, which would give you the ability to plot out your meter's response to densities all the way up to 6.00…

I based my comment on information provided by Durst-USA.
This is an excerpt from a pdf:

Also, all four wheels are the same.

Drew and Kiwi7475,
Thank you both for your contributions.

Drew,

Can you elaborate on this, or provide sources?
I'm not saying you're wrong, but my thought on putting rubber under the rails was based on two different sources.

1) This is an excerpt...

Gary,

Thanks for sharing the 2506 instructions for installation on the rails.
The text does provide some information on proper procedure for putting the rails on the floor.

However, the L184...

Yes, this is the correct placement.
The rails (and the enlarger's base) need to be perpendicular to the wall you want to project on.

Based on the size of that wall and the largest...

The wheels do not rotate on purpose. Once your rotate the head 90 degrees for horizontal projection, the lens faces in the direction of travel.

ic-racer,
I have a folder (with many subfolders) with pictures of 8x10 Dursts that I've saved through the years.
Sadly, none of the pictures that include setups with rails are focused on the rail...

My floor is tile over concrete.

Had the same concerns about aluminum, so that settles it.

A search for steel T-rails in the specified dimensions (or close to them) was unsuccessful.

I'm...

Has anyone here put an L184 or L139 on rails for horizontal projection?

The L184 manual suggests the use of 80x40x7mm T-rails, while the CSL2000 manual suggests V-rails (of unspecified...

ic-racer,

Did you ever put the CP43 that fits the reflector to use, and do you have any comments as to how it compares to the original Thorn?

Specifically:

Do the fans run for more time,...

(I was looking for something else when I stumbled upon the item I liked to.)

Thought that since it's a mirror fixed at 45 degrees inside a rectangular box, that it might be a relatively easy fix...

Thank you for all the files.
Much appreciated!

I have read this thread in its entirety a few times through the years, as it evolves -- every time I thought I was close to just about get my hands on one…

It looks like I might just get one...

Something like this might work too.

So, the answer to my original question seems to be:
Yes it's safe to replace the ENH with LED… But, it probably won't work as intended…

Well, only one way to find out I guess…

Thanks to all...

ic-racer,
I was hoping you might chime in.
(you don't know me, but I know you (among many others) through your posts…)

So, thanks for explaining what interneg meant with his mention of PWM.
...

Hey guys, thank you for your answers.

Helpful people always try to provide as much relevant information as possible, and I really appreciate that.

My main concern though is that of safety.

For the past fifteen years I've been using 120V, 250W ENH Halogen Lamps like this one:

Is it possible to replace them with 120V, 5W LED like this one:

Physical dimensions seem to match.
I'm...

Done.

Peter, reading your suggestion I had one of those Homer Simpson *doh* moments.
Self-evident in hindsight (like so many things in life).
I was so concerned with preserving the directional "feel" of...

Seezee, most of my work has been with natural/existing light. I'm only starting to explore the world of artificial lighting.
(I was taught studio lighting back in school some 20 years ago, but...

Thanks guys!

Andrew, get your hands off my face man!)
