How do I figure out the max voltage /amperage of this smol incandescent bulb from a flashlight? No markings… battery was 1.5v AAA. I was going to try slowly going up on bench supply. Trying to make a light source with it.

Flashlights are near always wired in series, so voltage of a battery cell times number of batteries. Voltage conversion circuits are wasteful and tend not to be used in flashlights
