WebDec 17, 2012 · Fluorescent Lamp: An Overview. The fluorescent lamps has been used in office and other commercial environments, giving light at an efficiency of 5-10 times that of standard tungsten filament bulbs. The fluorescent tube contains an electrode with a gas fill of typically an argon/krypton mix and a small amount of mercury. Webinductor current causes a large overvoltage across the inductor.Given the correct conditions (see section 2.2 below for a discussion of these) this overvoltage is large enough to cause ionisation of the gas in the main tube. At this point the impedance of the fluorescent tube falls to a minimum, and the voltage drop across it falls to a level ...
