    After so long, I've managed to get my enlarger set up. Other than replacing the halogen bulb, everything seems to work fine. However, I can seem to read the filter settings at all. The illumination is very dim. Is there a bulb that I need to replace for me to be able to comfortably read the filter settings on my CLS head? I can't seem to read that in the manual. I know it's a separate bulb as the filter illuminates, albeit very dimly, even without the halogen lamp.

    The dial illumination is fairly dim on both the L1200 heads I have - It may be possible to replace the bulb with a brighter one, but I have not found it a real problem. If I need more illumination, I have a small torch to hand.

    Hehe that's what I use, a small torchlight with red gel as filter :smile: Thanks, I just want some confirmation about that.

    I believe they make the dial illuminations dim on purpose because color printing needs to be done in the dark. There may actually be some filtration over the bulbs also. I did replace the olive filters (like a cross between Kodak 11 and 3) filters (safe for color negative and b&w paper) over the bulbs on my Durst CLS dials with red, since I only do B&W. I think the red is brighter than the original.

    Thank you for the information, it sure is helpful. Please bear with me, as I'm very new with the enlarger.

    May I know for those with CLS 501 head, what's the average time I can expect for 8x10 sized print (ilford MGIV RC) from normal 6x6 negative (N, based on film testing), printed at Grade 2.5. I just replaced the bulb with a new Philips one, but I'm getting exposure time of more than 60 secs for a good print. I'm using 6x9 femobox, with 100mm componon-s lens. For the grade setting I'm using dual settings on Ralph Lambrecht's web site.

    Also I'm noticing that even when I use the "filter out" switch, I can see the light is not totally 'white', different when I'm setting all the filter settings at zero. Just need to know if this is normal.

    Again my apology, if these are 'elementary' questions, as I have search for answers but unable to find them.

    Do you have the manual? Are you sure the "Supplementary 45Y +45M Filter" is not in place. This is controlled by lever #86 in the manual. This is a RED filter that will just make B&W printing slower than it should be. It can be used as extra neutral density if the printing times are too fast.

    If you don't have the manual there is one here: http://www.125px.com/docs/manuals/darkroom/durst/durst_laborator_1200.pdf

    Eureka! I think you've nailed where my mistake was. I do have the hardcopy manual for the enlarger but didn't notice this. I'm, however, out of town over the weekend but will report when I get back how it goes. Thanks again for being most helpful.
