    Lighting a fused florescent tube

    Well, I know that if you take one of those devices that produces high voltage streaks inside a glass dome and hold a florescent tube near it, the gas in the portion of the tube between your hand and the dome will become excited and light up.

    Lighting a fused florescent tube

    Thanks for the idea sputnik.
    But the circuit I am talking about works on the basis that a fused tube has at least one working filament.
    This simple circuit was pretty popular during my school days and I remember building a few of them myself using diodes etc.It lights up like a normal tube.

    Re: Lighting a fused florescent tube

    Did you ever tried to bypass the defective filament. Usually that works - without diodes etc. Just a thin wire is necesary.

    Re: Lighting a fused florescent tube

    I do not remember the details (it was long ago).
    I conected a removable 8W fluorescent tube (model without electronic , originally to work with a choke and starter device) to electronic circuit from broken compact tube (the glass part of compact tube was broken).
    It worked, the filement was not connected (pre-warm-up was not necessary).
