SUMMARY

The discussion revolves around building a compact lighting system using mini fluorescent tubes purchased from an Electronics Surplus store. The user seeks assistance in identifying the tubes, determining the appropriate DC voltage and amperage, understanding the wiring configuration, and selecting a suitable ballast. There is speculation that the tubes may be cold cathode fluorescent lamps (CCFL), commonly used in laptops, which necessitates careful handling to avoid damage.

PREREQUISITES
  • Understanding of cold cathode fluorescent lamps (CCFL)
  • Basic knowledge of electrical wiring and circuits
  • Familiarity with measuring resistance using a multimeter
  • Knowledge of DC voltage and amperage specifications
NEXT STEPS
  • Research CCFL specifications and operational requirements
  • Learn how to measure resistance and voltage with a multimeter
  • Investigate suitable ballasts for CCFL applications
  • Explore wiring diagrams for connecting fluorescent tubes
USEFUL FOR

Electronics hobbyists, lighting designers, and anyone interested in building compact lighting systems using fluorescent technology.

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!

No help from me, I'm afraid. I've seen very small bulbs before, but they always had the traditional 2-pins-per-end contacts. While I assume that those wires are the equivalent, I wouldn't try hooking them up that way without solid data.
 
Do the two wires on one end show a low resistance between them?

Does the other end also show low resistance?
Or does it show open?

Well, they only cost $1.50 so I'm good to 'speriment with them. That's why I got them. But if I try it without ANY prior edumacated knowledge, I'll just blow em up.

I um, guess I could find out. This meter I've got might tell me something.
 
Might be cold cathode fluorescent lamps (CCFL) often used in laptops.
