Experimental results on the discharge impedance and noise of fluorescent lamps are presented. The fluorescent lamp is devided in three parts, anode, cathode, and positive column, and the equivalent circuit for each part is determined. It is shown that the impedance of each part decreases with increasing frequency and discharge current. Anode-to-cathode impedance moves on a circular locus in clockwise with increasing frequency. The impedance is capacitive at cathode, and inductive at anode and positive column. The noise at each part decreases at the rate of-5dB/oct with increasing frequency, and rapidly increases when the discharge current increases beyond 200mA. This is most remarkable at cathode. The noise voltage at cathode is +3dB for 350mA of discharge current, and -17dB for 100mA, which is larger than those of other parts.
