    New lighting systems have not used magnetic ballasts since the turn of the century, however some older installations still remain. Fluorescent lamps with magnetic ballasts flicker at a normally unnoticeable frequency of 100 or 120 Hz (twice of the utility frequency; the lamp is lit on both the positive and negative half-wave of a cycle).

    The phosphors lining the lamp degrade with time as well, until a lamp no longer produces an acceptable fraction of its initial light output. Failure of the integral electronic ballast of a compact fluorescent bulb will also end its usable life. Compact fluorescent lamp that has reached end of life because of mercury adsorption. Light is ...

    Cross section of a typical fluorescent lamp with and without a reflector. Some lamps have an internal opaque reflector. Coverage of the reflector ranges from 120° to 310° of the lamp's circumference. Reflector lamps are used when light is only desired to be emitted in a single direction, or when an application requires the maximum amount of ...

    [1] [3] To prevent this, fluorescent tubes are connected to the power line through a ballast. The ballast adds positive impedance (AC resistance) to the circuit to counteract the negative resistance of the tube, limiting the current. [1] Several American magnetic ballasts for fluorescent lamps. The top is a rapid start series autoregulator ...

    New color-corrected versions producing a whiter light are now available, but some efficiency is sacrificed for the improved color. Ballasts for discharge lamps. Like fluorescent lamps, HID lamps require a ballast to start and maintain their arcs. The method used to initially strike the arc varies: mercury-vapor lamps and some metal-halide lamps ...

    In addition to the wear-out failure modes common to all fluorescent lamps, the electronic ballast may fail, since it has a number of component parts. Ballast failures are usually due to overheating and may be accompanied by discoloration or distortion of the ballast enclosure, odors, or smoke. [53]
