Fluorescent Light Transformer Output Voltage

How many volts needed.

Fluorescent light transformer output voltage. Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts. Some are rated for only 120 volts others for only 277 volts used in commercial environments. 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. Fluorescent tube and switching ballasts.

The amount of illumination in the fluorescent bulb is controlled by a ballast that is connected to the fixture. Using a 555 timer as main parts. 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. Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp s.

If your fluorescent fixture is not working properly use a multimeter also called a volt ohm meter to check the fixture s voltage to determine if the problem is the ballast or another component. The line voltage can be many different voltages 120v 227v 347v. This is 4w 12v fluorescent lamp driver circuit. The advantage of this circuit has a lot of brightness using less energy.

When power is first applied a high voltage several hundred volts is needed to initiate the discharge. You may use a 12v adapter or 12v battery. Cfls for the home have a built in ballast at the base of the bulb.
