Where can I get replacement green lights?

I have accidentally destroyed most of the green light tubes for one of our light boxes. I know I should be able to find this, but I can’t.

Where can I get replacement light tubes?

I know this must be somewhere on CD, but I searched and can’t find it.

Thanks,

go to google.com, type

cold cathode green

and hit “search” and you’ll find plenty of sources.

FIRST used the green 12" ones on this page http://www.oznium.com/cathode-kit (also a good place to get high powered LEDs)

Thanks!
