Question about cathod controllers

post #1 of 7
Thread Starter 
Im going to be using UV LEDs in my new build instead of UV cathodes but I want to be able to control the LEDs with a sound activated control box that you use for cathodes. Im assuming this is possible but not not 100% sure. I now the control boxes are 12VDC input and the LEDs are also 12VDC. One thing that Im not sure of though, Is the output on a cold cathode controller also 12VDC? Seems like it most likely would be. If thats the case I see no reason why this wouldnt work.

Only other question that springs to mind is how much of an amp draw can the control box handle on each of the cathode output ports. Anyone have any idea?

Cold cathodes work on AC so they would not work with LED. As for voltage I am not sure.
If the sound control is before the ac tranformer your could make it work by removing the transformer.

Hmmm do they make sound controllers for LED strands? Wish I would have know they run on AC. I assumed since the input was a molex connector that the output would be dc as well. Probably would have went with UV cathodes had I know that. I already ordered the LEDs though. Oh well not a big deal, I can live with out the sound reaction if worse comes to worst.

So some of those controllers look like they would do the trick but after I got to thinking about it I was thinking it might be cool to use some sort of control box to make the LEDs "breathe" but my UV LED strand is 2 wire and all of the controllers that Im seeing that are capable of doing a "breathing" sort of effect are for 4 wire RGB LEDs.....Is there a way to hook a 2 wire strand up to one of these 4 wire controllers?

Yeah. Basically you'd be losing two of the channels it could control. There's 4 wires. Usually black (ground) and red, green and blue (+12v to each color). The controllers are super cheap, so easy to pick up and goof off with. You'd hook up to black (-) and any one of the three color wires. Or, put a separate strip on each of the three colored wires and tie all the - to the black. Selecting different colors on the remote would normally mix the red, green and blue channels. With them all tied to single color strips, you'd get a brightness fade between channels. Could be awesome.

Sweet! Thats what I thinking might be possible but I wasnt 100% sure!
