wiring a tube just for light

[M.A.P]

If you want to use tubes as a light source you have to use the right ones. EL84 won't work properly.

Get one of these: http://www.b-kainka.de/bastel25.htm

I already got one but never tested it. Still searching for a transformer with 12V 10,5A


And back to topic: Always connect the voltage to the heater that is specified in the datasheet for normal use. For use as a light source you could use less voltage but I would never use more as specified. As already mentioned connect two EL84 in row to divide the voltage to 6V per tube and everything should work fine.

ok I put 6.3V DC on pin 4,5 and now it glows
experiment ended.
