According to the information on the lamphead of my Omega D5 enlarger, the 75-watt #211 bulb is standard. I would like more light output because I am printing XP-2 negs exposed at E.I. 200 (they're dense, but they make beautiful prints!). Has anyone tried a #212 (150-watt) bulb in a D5? Any problems?(posted 9236 days ago)
