Just found out that the 12v lights I need in a hurry are not available, but they do have the same thing in a 5v version. Is there anything I need to know or be concerned about? It will a complete system, so no chance of hooking up to a 12v controller. The strips will be the 1003 ink strips about 12' long.

Thanks in advance,
Brian

Really that you have the right power supply and that depending on the length of run, number of pixels you may have to inject power, which will mean more wire runs.

But 5V is more than bright enough, just that they are more sensitive to power drop. 12V LED's will run with between 6.4v to 12+v , while 5v will run with maybe something like 4.5 to 6v, it's a small window. I power my 5v stuff with a 7v power supply turned down to 6.5v.

But a 12volt powersupply with buck convertors is also a good choice, continue to run 12volt but use the buck convertors to drop the voltage.

I know some stuff. For example i know I don't know anything.

See my write-up on 12v uSC used to power 5v strips in a meteor tube.

This works for falcon and DLA controllers... SSC and zeus-like controllers.

Steve you might want to put  link here for reference. I know it's an older thread, but might help someone surfing.
