Looking to power a mini halogen bulb to do film capture. It would be great
if I could power it off the movie projector itself without having to get an
additional power supply. The socket for the projector reads slightly over
24v. However, the lamps it uses are 21v. Someone has stated that load is a
factor. Does that mean that the voltage needs to be higher than the bulb
rating or not necessarily?

What I wonder is if this 24v bulb should work off the 24v socket on the
projector?
