what is a light ballast?

Lamp Ballasts are the devices which run fluorescent, metal halide and high-pressure sodium lighting systems. They start the lamp and keep it operating through the proper application of the voltages and maintaining the life of the lamp. Fluorescent and HID lighting simply wouldnt work without them. Ballasts are generally very heavy, except for some electronic ballasts which are lighter and more energy-efficient. The HID ballasts are very heavy and are of core and coil variety.

Pulse-start MH lamps do not have the starting probe electrode (Figure 2). Instead they have a high-voltage ignitor that works with the ballast to start the lamp using a series of high-voltage pulses (typically 3 to 5 kilovolts). Without the probe electrode, the amount of pinch (or seal) area at the end of the arc tube is reduced, which results in a reduced heat loss. Furthermore, using an ignitor with a lamp reduces the tungsten sputtering by heating up the electrodes faster during starting. Warm-up time is also reduced. Pulse-start technology was developed to increase lamp life and to have both the energy efficacies of high-pressure sodium (HPS) lamps and the desirable color characteristics of MH lamps.
