Electronic ballasts have almost become the standard in the low pressure lamp lighting industry. The UV lamp operation is free from flicker and the ballast produces virtually no noise or hum. The incoming 50 Hz power (240 volts) is converted to high-frequency AC (usually 20 to 40 kHz). This leads to a constant gas discharge compared to conventional ballasts and prevents cathode flicker. Electronic ballasts are more efficient than magnetic ballasts in converting input power to the proper lamp power. The operation of low pressure, amalgam ultraviolet UV lamps at higher frequencies reduces end losses, resulting in an overall lamp-ballast system efficiency increase of 15% to 20%. Electronic ballasts are directly interchangeable with magnetic ballasts. Special electronic ballasts can operate two or four lamps reducing the total number of ballasts in a system. Infralight supplies a comprehensive range of electronic  ballasts and HID power supplies for low pressure ultraviolet germicidal and medium pressure ultraviolet lamps.
