Ohm''s Law. The higher the voltage v the higher the current. If the brightness is caused by a flow of electrons through the filament, a higher voltage will--all things being equal-- drive more electrons to flow through the filament. So the brightness is a function of both current and voltage, and can be said to depend on both.
