Okay. So I got the cold cathodes and they will work great except their are no 12V adapters that can feed 27 amps to them are there? It looks like most are measured in milliamps up to 1 amp. I'm assuming this is what's needed as I'm looking at my ATX power supply DC output: Yellow Blue Purple +12V -12V +5V 27A 1A 3A I suppose I could run them all to a stand alone power supply but then I'll be limited to where I place them in the room. |

27 Amps?!!? What are you trying to do with it, light up a warehouse? CCFL bulbs draw less than 1 amp at 12 volts. Like NIVO said, buy a cheap 12V wall wart, and use it to power the CCFL. If you really want to use a PC power supply, all you need is one 12V (yellow) wire and one ground (black) wire. I have used dozens of CCFL bulbs, and they work great for things like this. |

i was thinking of using cold cathodes for a marquee light, would that be ok? i've never used one so i was kinda weary of trying it on a whim, but they're cooler and use less power than a florescent, right? and last longer i think... i'll have a computer power supply already since it's a mame cabinet. does this all make sense? i like the idea by the way, it seems it's been a long time coming too. you've been asking about marquees for a bit now. |

I've done several of these as gifts......one was a Star Wars marquee for my nephew (I just had a repro printed). Next came a spiderman..... http://www.satio.com/spiderman.jpg Someone saw that and wanted a Harley Davidson theme.... http://www.satio.com/harley.jpg Someone saw that and wanted a custom UT Longhorn theme... http://www.satio.com/longhorns.jpg I just built boxes that were about 6 inches deep and used flourescent fixture, each sized around 24-29" wide x 8" tall 'cept for the longhorn which was more square like 18 x 16 or so.... |

CCFL will work fine for a marquee. Cooler, less power, last longer, no buzz/flicker. I buy mine from SVC.com You can even get UV/blacklight if you want. |
