A new non-invasive method for the determination of electron drift velocity has been investigated by measuring the light propagation signals in external electrode fluorescent lamps with two usual operation methods. At the luminance of 12 000 cd m(-2) with an operation frequency of 65 kHz, the electron drift velocity in accordance with the propagation speed of light emission is measured to be 2.72 x 10(5) m s(-1). From the electron drift velocity, the electron temperature and the plasma density in the positive column are estimated to be kT(e) similar to 1.6 eV and n(e) similar to 4.3 x 10(16) m(-3), respectively, which agree well with data in the glow discharge plasma of typical fluorescent lamps.
