I have a lpl 7700 vcce enlarger who uses a 100w 12v halogen bulb. We all know that halogen light is less effective in order to print on vc papers due to its spectral sensibility and my printing times are very high. Then I have to options to look for a cold light head, and I think it is nothing avalaible for this enlarger, or to rise its light power. I have no knowledge on electronics but I think its not as easy as change the bulb to a bigger one, sure you have to change more things on the enlarger. Any advice? Thanks.
