|
| alright i recently took apart an old flashlight that had a working halogen light in it. i wanted to put this in my computer case for lighting, my only problem is that it's small circuit board requires 6v and all i have is either 12v or 5v so my question is, can i just hook p a resistor and use it, or do i have to worry about the amperage my computer psu puts out, its a corsair with one 12v rail and puts out more than 45 amps... or can i just hook it up to the 5v source? |

You should be fine using the 5 volt supply. |

| Yeah, due to the fact that light bulbs work on the principle of electrical resistance, it'll only draw as many amps as it needs, so, like Alan said, 5V should do just fine. |
