It really depends on the watts and voltage applied. The light bulb used in a slide projector draws a current of 4 amperes when operating on 120 volts.1. A light bulb operating at a dc voltage of 120 v has a resistance of 200 ω.

120 volts divided by 192 ohms is 0.625 amperes. 21 an incandescent light bulb is supplied with a constant potential difference of 120 volts. How many amps does a 100 watt bulb use at 120 volts? We are given the voltage and the power output of a simple circuit containing a lightbulb, so we can use the equation p=iv to find the current i that flows through the lightbulb.
