How do I know how much voltage I can run through a flatbed scanner
lamp?
Heart Ignition

Get the part number off it. Ask the manufacturer.
(I doubt that the scanner maker produces its own lamps.)


Can I run it DC or do I have to keep it AC and how do I know?

DC of the same level as the original AC RMS value
will give identical results on a resistive load.


BTW, fingerprints on quartz lamps can cause draamatic failure.
