This brings up the topic of how long is the life and storage life of a halogen or incandescent bulb? Say you have a Durst bulb, an Atlas 110V 200W OPALE E27 P3/15 P 3/15 Lamp Bulb, and a couple of very old backups, are they good and how long are they going to be good? I bought a half dozen halogen bulbs for my Beseler 45, are they on borrowed time or is the proof in the printing? I use a rather large and heavy Sola CVA unit with my enlarger. |
