The ballast is a transformer that steps the voltage up higher than its incoming voltage.
This is usually used with flourescent, metal halide, & sodium vapor lights.
The higher voltage is needed to 'excite' the gases within the bulbs and make the molecules bounce around and give off light.

Where is the ballast in strip lighting?
The ballast for strip lighting is in the wire raceway. Strip lighting is bolted together in sections. Every section has a ballast for ever set of lamps that hang below the wire way. When wired, these ballasts are all parallel connected together and when sourced with voltage they will all come on at once. The whole strip of lighting will illuminate.
How do you rewire a magnetic ballast F96T12 fixture to work with a new electronic ballast?
The end sockets have to be rewired. The schematic for the rewire is on the ballast label.
Can you use a 400W high pressure sodium bulb in a metal halide ballast?
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
What is a reflector and what is its purpose in in lighting?
A reflector is a, usually large, sheet of reflective material used to reflect light into shadows of a subject. It is usually used where there is strong lighting from one side to even up the light in an image.

Why is your strip light buzzing?
If your terminology of strip lighting is fluorescent lighting, the buzzing will be the ballast. The laminations are becoming loose and that is the 60 Hz frequency that you hear when the lamination plates in the ballast hit together.
Where can a HID ballast be bought?
A HID ballast can be purchased from Amazon or eBay. The term 'ballast' is used to describe large inductors used to limit AC current for fluorescent lighting.
Do you add the ballast and light wattages together?
No. Just make sure that the ballast you use is rated for at least as many watts as the lighting you plan to operate with it.
What are the purpose of ballast tanks?
to control the buoyancy of a submarine
What is the purpose of a ballast resistor in a car?
a ballast resistor drops voltage. In chrysler products it drops to six (6) volts.
What is ballast and trapped fuel?
On occasion, ballast is required to bring the centre of gravity within operational limits. There are two methods of carrying ballast: - Ballast (hold loaded) -Ballast fuel: the fuel used for this purpose is called ballast fuel. Trapped Fuel:The fuel in an engine or fuel system that is not in the fuel tanks
What is the purpose of having sensor lighting?
The purpose of having sensor lighting is that the lighting may be activated or deactivated depending on the detection of motion. This is convenient for lighting path ways at night or for security concerns.
Does a hid lighting consume energy when burnt out?
Yes, because the ballast is consuming energy even though the lamp is burned out.
How do you wire 347 volts ballast to 110 volt feed?
You don't. A ballast with a 347 volt input is a commercial ballast. The 347 volts comes from a 600 volt three phase four wire Y system. You can change the ballast out to a 120 volt and rewire the unit but in most cases it is cheaper to buy a completely new lighting fixture.
The purpose of emergency lighting is to?
establish
What is the purpose of a submarine's ballast tanks?
to keep the sub level or help it to dive and surface
