| AC bulbs on DC? |
| (1/2) > >> |
| MaxAsh:
Hey all - helping a friend with a project and ran into what I think is just a general electrical question. I did some googling, and came up with a variety of answers, so I wanted to ask folks here just in case. I'm guessing this is likely just me overthinking things, but better safe than sorry. I'd just try it out, but don't want to damage anything. The existing cabinet has a row of 14V AC (yes AC) fed bulbs. The wiring was literally a direct wire feed off an old transformer from what I understand. No electronics or board in between. Is it possible to simply feed them off the 12V DC, PC power supply? I recall reading that a bulb, directly fed, doesn't really care about AC vs. DC much. My google searches resulted in mixed opinions. Thoughts? |

bulbs for what? the marquee? Just put an LED strip in there and tap the 12v. |

My buddy wanted to try and keep the marquee looking "classic" if possible and re-use the old bulbs in there. Once I found out they were fed with 14VAC instead of 12VDC, I told him it was probably not worth the hassle. Figured I'd double-check to see if I could wire it up to the PC (without an inverter or anything special) before telling him LEDs would be best. |

I think it could be done, but I dont think it'd be worth the hassle |

Incandescent bulbs don't care about ac or dc. |
