Old 1972 DC light bulb
I am tearing this shroud apart and going to just use the fan box. It has a light bulb the size of a house lamp, but it is DC! It works

Incandescent bulbs operate on AC or DC, just as long as they are the correct voltage.
In a lot of the substations I work in, there is an emergency lighting circuit that has a bunch of 100W bulbs connected to the 125V battery back (~130V float). In the event of a station outage (loss of station service) we can turn on the emergency lighting powered directly by the battery bank.
Nothing special about the bulbs, just your typical 100W 120V.
