Hi,
I have a lighting controller circuit using an H-bridge, which produces a 250Hz signal across a pair of 12V halogen bulbs. (The duty cycle is controller by a microcontroller, but this is irrelevant to my question.)
My question is: is a 250Hz signal with rise/fall times
I think if the temperature of the filament remains constant, there is no extra wear on it. Meaning, as long as it doesn't flicker, there is no problem.
