Characteristic properties of fluorescent lamps operated by capacitively coupled external electrodes have been investigated. External electrode fluorescent lamps (EEFLs) are typically operated at low currents less than 10 mA and high voltages of about 1.5 kV. Luminance of up to 20,000 cd/m² with efficiency of above 40 lm/W is achieved in EEFLs driven by square pulses of the driving voltage with frequencies lower than 100 kHz. It is also found that the brightness and efficiency of external electrode fluorescent lamps depend on the electrode length and the ambient temperature.
