cargosteve Posted June 4, 2023 Share Posted June 4, 2023 The bulb in my Omega Super Chromega Dichroic II just burned out. It was a 22.5v 250w Bulb, part 471-029. I have a 30v 80w bulb that I could use to replace it, but I wanted to know if there would be any ill-effects to the enlarger if I use the incorrect replacement bulb. Thanks in advance.

kmac Posted June 4, 2023 Share Posted June 4, 2023 Perhaps a lower light output, and increased time to expose the paper. If there is a transformer in the works for the 22.5v bulb, that voltage is all you'll get for the 30v bulb. The 80w means you'll get only a third of the light you were getting before with the 250w bulb. Link to comment Share on other sites More sharing options...

john_shriver Posted July 6, 2023 Share Posted July 6, 2023 Running the lamp below it's rated voltage will lower the color temperature. Even for a given voltage, halogen lamps made in different color temperatures. Which will affect color printing results. Link to comment Share on other sites More sharing options...
