Halogen lamps do not need ballasts, however, large halogen lamps and arrays of lamps are sometimes connected in series with low-inductance, high-current, air-core "inrush chokes" to protect switch contacts: Resistance of metal increases with temperature; there is significant difference between tungsten's cold resistance and its resistance at halogen-lamp operating temperature. -- Frank Reid reid@ucs.indiana.edu
