Fluorescent Light Transformer Output Voltage

Using a 555 timer as main parts.

Fluorescent light transformer output voltage.

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. 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.

Fluorescent tube and switching ballasts. 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. When it uses 12v battery has consumption current about 300 ma.

When power is first applied a high voltage several hundred volts is needed to initiate the discharge. The line voltage can be many different voltages 120v 227v 347v. How many volts needed. 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.

The lamps are on the output of a transformer ballast the input of the transformer being the line voltage. Cfls for the home have a built in ballast at the base of the bulb. You may use a 12v adapter or 12v battery.
