EFP Enlarger Bulb Substitute

[rcphoto]

I have a Nikor 6x7 enlarger. Calls for an EFP 100w bulb. My issue is that my exposure times are exceptionally short IMO. For example, stopped down to f/22, I'm getting exposures <6 secs on an overexposed neg. Would changing out the bulb for something in the 50-75w range be a good option?

You could swap out a 75watt or a similar LED bulb. As my negative are developed to print grade 2, if for some reason I need to print to grade 4 I switch back to 75watt tungsten.
