If true how do you get a battery operated fluorescent light to work?
Battery-operated fluorescents certainly work (I have two), as does the 12V-powered ThinLite fluorescent which I mounted in my Boler
, which has no separate "ground" connection. The compact fluorescents (CFLs) that are screwed into lamps in place of regular bulbs also have no ground connection.
There are a few different starting methods for fluorescent lights
, and one of them requires a ground plane near the tube (a function which apparently can be performed by a human body); if that's the one which Des's fixture uses, the instruction makes sense, but it doesn't apply to all designs. I would be surprised if a modern fixture requires the grounding, but a 30-year-old fixture is a different matter.
