    Re: Any Aristo W54 Cold Head Tips?

    I received my V54 today! The sure did pack it well - it came in quite the oversized box with tons of padding. In any case, I installed it and it's working great! I managed to make a decent print using a #2 filter - looked just about right for what I would expect. I gotta say though it is BRIGHT. I had to stop down to f/32 and it was still a 5 second exposure. To work around that, I now have a stack of 3 Hitech ND filters to drop it down six stops. That gets me to 10 seconds at 5.6 - a little much so I may remove the top filter, but I wanted to make sure I had room to dodge burn in all formats (my 35mm enlarging lens only goes down to f16 as I recall).

    Test strips worked out pretty well more or less - exposure was so short more testing is required but I did get proper bands and they seemed to be a stop apart. I just turned the metronome on and kept the light on, exposing each strip after 3 seconds. Easy peasy.

    Guess I'll need to get some decent NDs though. Sharpness seemed good through the Hitechs but stacking filters like that makes me concerns I might be causing shenaigans. I guess I'll need to pick up a few NDs to use for the cause. Nice to have more light than not enough I suppose.

    It's so bright it does point out ALL the places the enlarger leaks light though. I had to put gaffer tape on parts of it to help mute the light. Doesn't seem to be fogging the paper but I didn't do any long exposure tests yet.

    Overall I'm pretty satisfied but glad I had some NDs lying around for sure.

    Glad to hear that your anticipated V54 arrived safely. In my earlier post, I mentioned the brightness issue. Hence my use of the 750 Dimmer. You might condsider using something similar instead of stacking filters. I prefer exposures in the 20sec. range. Enjoy!

    I remember when I got that big box from UPS! Lots of gray foam. Best Packing in the world. My lamp was a bit 'jumpy' when I first turned it on. It flickered around for a while. I called Louise and she said to just use it for a while and it will settle down and it did. Good luck!

    Doh I forgot about the dimmer option! I was searching the thread yesterday for info on filters but yeah that's a thought. You mentioned a Contactor but I'm not entirely sure what that is? I don't have a lot of experience with neon lights or whatever bulb this is Looks like the light is AC powered (runs from a transformer) so a normal dimmer should drop the incoming voltage and thus make it dimmer correct?

    The filters aren't bad necessarily - well, definitely extreme for 4x5 though didn't seem to affect sharpness. I was worried stacking 3 filters might cause newton rings or some such but I didn't see any (I only printed on 4x5 negative last night though). I ended up only needing a 2-stop for 35mm which makes me think 120 may require a 3 or 4-stop. I also prefer being able to get up to 20 seconds or so for prints, at least if I'm dodging/burning. Otherwise I like to be around 10 seconds.

    The light spillage I'm going to keep working on. It doesn't seem to fog papers but it certainly lights up the room heh.

    Otherwise though I'm loving it. It produced great prints at contrast levels I'm much more used to than with a condenser so I'm quite happy!

    It would be good to look around for a Zone VI Cold Light Stabilizer. It has a dimmer built in and consistent light output.

    This is the dimmer I use. It measures 5 1/4 x3 x 2H.

    Very nice and I am sure very hard to find.

    But it does indicate a well oversized device is specified.

    Assuming Aristo named it for rating at 750 watts. I measure my W54 at 300 watts.
