Fluorescent Light Transformer Output Voltage

Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp s.

Fluorescent light transformer output voltage.

When it uses 12v battery has consumption current about 300 ma. The ballast provides enough voltage to start the fluorescent bulbs and once they are started it quickly lowers the current to produce just enough electricity to produce a steady light source. Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts. How many volts needed.

Commercial cfls use a separate ballast. However once this takes place a much lower voltage usually under 100 v for tubes under 30 watts 100 to 175 volts for 30 watts or more is needed to maintain it 100 175 v. Cfls for the home have a built in ballast at the base of the bulb. The lamps are on the output of a transformer ballast the input of the transformer being the line voltage.

Fluorescent tube and switching ballasts. Some are rated for only 120 volts others for only 277 volts used in commercial environments. The advantage of this circuit has a lot of brightness using less energy. The line voltage can be many different voltages 120v 227v 347v.

The amount of illumination in the fluorescent bulb is controlled by a ballast that is connected to the fixture. This is 4w 12v fluorescent lamp driver circuit. When power is first applied a high voltage several hundred volts is needed to initiate the discharge.
