Fluorescent Light Transformer Output Voltage

The line voltage can be many different voltages 120v 227v 347v.

Fluorescent light transformer output voltage.

The amount of illumination in the fluorescent bulb is controlled by a ballast that is connected to the fixture. 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.

Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp s. Some are rated for only 120 volts others for only 277 volts used in commercial environments. This is 4w 12v fluorescent lamp driver circuit. How many volts needed.

Using a 555 timer as main parts. The advantage of this circuit has a lot of brightness using less energy. Commercial cfls use a separate ballast. Fluorescent tube and switching ballasts.

Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts. Cfls for the home have a built in ballast at the base of the bulb. 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.
