    A coldlight with just the warming device will be repeatable only if allowed to cool to the baseline temp between exposures. The warmer is a good, simple, cheap and reliable device, but it has its limitations.

    Do you still have the original head for your enlarger?

    What I would do if I were still using my cold light head, is to get one of these stick-on theremometer strips and put it on my cold light head. Then, I would use my graph that I posted above and do a time-temp compensation for each exposure.

    In your case, use any meter to make your own compensation graph.
