Hi Blake,
I took apart my flashlight and it had two D batteries in series giving a total voltage of about 3 Volts.   C batteries are rated at the same voltage, 1.5 Volts.   Now most flashlight bulbs including the one in my flashlight require from 2.8 to 3 Volts  so a single C battery will not light them up.   You need two C batteries wired in series.
