    I am making an oak floor lamp with base 4' high with fluorescent tube
    (strip light). I can not use standard metal shield in the lamp base,
    thus there is a grounding problem. At one point I had the top light
    (conventional bulb) and bottom fluorescent light working either
    together or independently of each other, but if did not last too long
    before grounding problem took over. How can I have a working lamp top
    and bottom consistently dependable. Thanks for any advice and help I
    can get. Nick

    Run a strip of aluminum tape down behind the tube and ground it, or use
    an electronic ballast with a T8 tube.
     
  3. If you're using a ballast that requires a grounded reflector, you have
    to give it a grounded reflector. :) Or, perhaps a wire screen would be
    adequate. Is the issue that the aesthetics won't allow a reflector?
    Or, that you don't have a grounded plug? It doesn't need to be a reflector,
    but something that's grounded. Perhaps even a modelsty conductive
    coating, a foil behind a decorative panel.

    Hi...

    Or if aesthetics demand it, even conductive paint.

    Take care.

    The instant on lamps will light with a spiral of fine wire wrapped
    around the whole length of the glass and grounded. Something smaller
    than ~30 gauge magnet wire isn't too noticeable. Copper tape is
    another option if you don't mind how it looks where the tape is - sold
    for stained glass supplies.
