Halogen bulbs 12vdc vs. 12vac
Halogen bulbs 12vdc vs. 12vac
(OP)
I have a halogen bulb that is normally used with a small 12vac transformer. I can also light this bulb straight off a car battery that's 12vdc (the battery of course runs down very quickly). My question is, "Do I harm the bulb by using 12vdc on it, since it's primarily used with that 12vac transformer?" And "Are there halogens that are made specifically for 12vdc applications"? Thanks

Yes, there are halogen bulbs designed for DC use. Usually they are ruggedized, assuming that the user will be using them in a vechicle which will shake them around.
The wattage rating of the bulb will determine how fast your battery runs down.

Second question: there are different kinds of 12 V halogen bulb depending on its us (car or home applications) rater than on current type. That differences mainly affect to mechanical arrangements.
