Title Description:
The fluorescent tubes used in the installation were salvaged from a disposal bin, chosen for their diversity in expiry. The waveforms that are shown illustrate the patterns found in the recording of each respective tube using contact microphones. Tubes shown in this range operate off 24 volts and all behave differently when charged. A cold tube for example will have a period of violent fluctuation before stabilising. Sustained oscillations, pulses of charge with incredible regularity and sudden turn to dynamic and unpredictable waveforms outline fault in performance as a result of age. The entire fluorescent lamp system depends on an electrical current flowing through the gas in the glass tube. If the current in a fluorescent light isn't controlled, it can blow out the various electrical components. Magnetic ballasts modulate electrical current at a relatively low cycle rate, which can cause a noticeable flicker. Magnetic ballasts may also vibrate at a low frequency. This is the source of the audible humming sound people associate with fluorescent lamps.
