Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or limestone.

Different types of lighting ballasts available. There are various lighting ballast types available on the market. These range from relatively simple parts of a light's inner power loop - acting solely as a basic resistor, capacitor or inductor when wired in-line - to a far more complex piece of the circuitry that's able to control adjustable voltage and current, giving some HID and

17.05.2007· Many types of rock are used as ballast on the railroads, granite is very common as is scoria of various types. Volcanic scoria often has pumice associated with it, and particularly on the Burlington Northern (now BNSF) it was not uncommon to find some pumice (which floats) along the tracks in the 1980's. Obsidian and basalt that was obviously from a lava flow were also common in that ballast

Lighting Ballasts and Drivers In a lighting system, the ballast /driver regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw and within a second the lamp would overheat and burn out.

Older fluorescent light ballasts (those manufactured before 1979) likely contain polychlorinated biphenyls (PCBs), classified by the EPA as an environmental toxin. If these ballasts are leaking, they should be regarded as hazardous waste and treated very carefully. Avoid skin contact with the tar-like substance inside a ballast. The best strategy is to take all old ballasts to your nearest

Some types (usually iron ballasts) may produce an annoying 120 Hz (or 100 Hz) flicker. Ordinary dimmers cannot be used with compact fluorescents and may result in immediate destruction of the CFL. In addition, CFLs should not be used with illuminated switches, electronic timers, or any other means of control that results in a small current in series with the lamp when it is supposed to be off.

Traditionally, ballasts are designed to operate a specific number (usually one to four) and type of lamp (such as a four-foot T8 lamp) at a specific voltage (in North America either 120, 277, or 347 volts). Thus, to find a ballast compatible with a particular luminaire (light fixture), lamp type, lamp quantity, and line voltage must all be known.
