For 30 years now I have printed with an Aristo Variable contrast cold light on my Beseler 45MCRX. That head seems to be giving up the ghost. I also have a regular Aristo cold light as well as my original Beseler condenser head, which has a 6 inch slot for putting in filters above the negative stage.
I have been printing the last week with the condenser and laying 3.5 inch filters on top the film holder. The bulb in this head is a very old 75 watt incandescent bulb. I want to get a new or couple of new bulbs and I wonder if the light technology has changed so that there is a better or best type bulb to buy. I see in B&H there are a few different brands and sizes and brightness and light temperature... as in color. They have a bulb that is 250 watts as well as a 150 watt bulb and the dimmer 75 watt bulb. They also show a heat absorbing glass I could put in.
Can someone advise me on the best way to go? Is there such a thing as an LED made for this normal medium base bulb. I see on B&H that one brand of bulb is smaller, would that have an even lighting problem?
thanks
