A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.

What is ballast in tube light?

Ballast is a device used in fluorescent lighting fixtures to regulate the electric current flowing through the light tube. It helps to stabilize the electrical current and control the voltage to ensure the proper operation of the light, including starting and maintaining its brightness. Without a ballast, the tube light would not function correctly.


Compact fluorescent lamps have made a lot of changes in the lighting sector it is also changed from a fluorescent lamp to compact fluorescent lamps but still it is dependent on the ballast Why?

A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. Compact fluorescent light bulbs are dependent on ballast because they use a gas to create light. when the gas is excited by electricity, it emits invisible ultraviolet light that hits the white coating inside the fluorescent bulb. The coating changes the ultraviolet light into light you can see.


How can you attach a 120 v Light Fixture to a 277 v system do I need a ballast so what kinda of ballast?

To attach a 120V light fixture to a 277V system, you will need a step-down transformer with a 277V primary and 120V secondary. This will allow you to safely power the light fixture at the correct voltage. You do not need a ballast in this case, as ballasts are typically used with fluorescent lights and not for altering voltage levels.


What is an emergency ballast?

An emergency ballast is a lighting ballast that has an internal battery. This battery will store enough energy to power the light for a short amount of time. Typically this battery is not designed to last through long power outages. Rather, it is normally used in conjunction with a backup generator. In the event of a power loss, the ballast immediately carries the load of the light, until the generator comes online. Some manufacturer's do not combine the ballast and the battery in the same metal can; they use 2 separate cans. The battery part in many instances does not light all the lamps of the fixture and it may only light the lamps about half brightness. The purpose is only to assist in evacuating the building


Will a t 8 fluorescent tube work in a t 12 fluorescent fixture using a high output ballast?

Yes....usually. However, lamp (bulb) life may be somewhat shorter than if the proper t8 ballast is used. Since ballasts limit current flow in the circuit, a mismatched (t12) ballast would cause more current to flow through the t8 lamp than the lamp's design specification. The lamp's output would therefore be brighter in proportion to the additional current. Owners of aquariums and terrariums make use of this property by overdriving both T12 and T8 style lamps with ballasts designed to drive two (or more) lamps to drive a single lamp, therefore supplying 2x or more current to the lamp than its original ballast. This results in a greatly increased light output, somewhat reduced efficiency, and shorter lamp life.

Does a fluorescent light fitting with 4 x T8 2' 18W tubes and a 48W ballast use all 120W when running?

No, the total power consumption of the fluorescent light fitting will be 120W, including the 4 tubes and the ballast. The ballast itself consumes some power to regulate the current to the tubes, so not all 120W will be used solely by the tubes.


What is a pin based fluorescent light fixture?

A pin based fluorescent light fixture is the type of fixture that takes fluorescent tubes. On each end of the fluorescent tubes there are contact pins. These pins are used to hold the tube in the fixture and to supply the voltage to the tube from the fixture's ballast.


Is tube light need dc voltage?

If you mean a Fluorescent tube light then no, you don't need DC. Household Fluorescent light tubes use AC mains electricity. The mains AC is passed through a ballast coil which reduces the current. A ballast coil works best when the AC mains voltage is at least 2 times the Fluorescent tubes working voltage. So, a simple inductor ballast can be used in Europe, where the line voltage is typically 220 to 240 Volts AC, to operate a 4 foot long tube, which operates at 85 to 100 volts, depending upon design. In the US and other places that use 120 Volts AC mains, the ballast is a combination auto transformer (to raise the voltage) and an inductor (the current limiter).

Information on CFL light bulbs?

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
