I'm considering using an incandescent light bulb as a current limiter in a circuit, but having trouble finding voltage versus current data for light bulbs. All my Google searches turn up consumer info on people that want to sell me light bulbs. Using the term ballast turns up stuff on fluorescent lamps. Using constant current turns up stuff on LEDs. So, anyone know where such data may exist? THANKS!
