Yep.

If you have a bad ballast it's tempting to go get some 12v LED strips and replace with that on a piece of board (styrofoam insulating board is fine for this purpose.) They're not expensive, produce nearly zero heat, draw little current, last forever and won't bleach the translite as they don't produce UV as a fluorescent tube does.

There is 12VDC available on the disk connectors in the PC cabinet in the backbox; more than enough power is available to run the LED strips.

I own both Pin2k machines and when the backlights fail that's what's going in mine.

That is correct; the *tube* does not vary with line voltage.
