    In a D2 I think the heat absorbing glass goes above the condensers, in the base of the lamp house.

    It's recommended by Omega if you use the higher wattage lamp.

    Is the glass anything special, or will a sheet of regular old soda glass work?

    The D series is designed for only 75 watt bulb. Add the heat absorbing glass after that.

    Make sure the head cooling vents are open.

    I have the Aristo dimmer for their cold light. It works for incandescent also. Turn the wattage down and you get less light and heat.

    Before the aristo, I used a wall 4 outlet box and installed a light dimmer

    The Aristo is a very well made piece that reminds me of 1930 technology. Pay what it takes to get one as. nothing is made this well today.

    bulb....

    i have a d2 (not v). I have a cold light head no problem.

    I replaced the condenser head - it had a piece of glass under the condensers and above the negatives. the bulb is so far away I don't see how heat could be a problem. Is the d2v that different?

    email harry taylor (harry_g_taylor@sbcglobal.net) - he is an omega expert - refurbishes and rebuilds them. he'll know.

    good luck

    As another poster notes, you can obtain a heat absorbing glass for your enlarger. Omega, did in fact make one & you should be able to get it from KBH.

    Just curious, this 'heat absorbing glass,' is it the same sort of thing used in some windows to cut down on UV light?
    WYSIWYG - At least that's my goal.

    I think it needs to block IR light. Even so, there may be films on sale that block or reflect IR for energy savings. I should look into that.
