I'm trying to build a lighting system that's very small and have been experimenting with designs. I bought these things at the local Electronics Surplus, and I think, if I can get them to work, they'll do exactly what I need. Unfortunately, they couldn't provide any information about them at the store. So. Does anyone 1] recognize these little fluorescent tubes? 2] know what DC voltage/amperage would probably light them? 3] know how to hook the 4 wires up? 4] know what ballast might be needed? (see attached) Thanks!
