I am messing around with some back-light project for my TV and found an old flatbed scanner lamp in my junk box. Hoping to use this lamp, I have tried to convince it to glow but no luck yet.
I tried from 3V to 12V DC from an adjustable power supply and nothing works. After doing some reading, it looks like I might need some form of inverter/driver or something to make it work. I couldn't get any clear indication but if I understand correctly, I'll need about 40V DC (current unknown). Would this be a "generic" voltage or will it differ from lamp to lamp?
Can anybody confirm what voltage, AC or DC, and what current is needed to make it work? Also, if special circuitry is needed, a schematic would be very helpful.
The lamp is about 25cm long an 4cm thick with a gray rubber cap on each end. I found no markings anywhere on the lamp. It's not much but I hope it helps.
