If you are talking about a fluorescent fixture then yes it can be done. As for the cost factor it wouldn't be worth it. To buy a new replacement 120 volt ballast separately would be equal to or higher that getting a whole new 120 volt fixture. Do a price comparison before going ahead and making a change to the 277 volt fixture.

Is it possible to convert a 220 volt light a 110 volt by changing the ballast?

What purpose do the ballast and the starter play in a fluorescent light fixture?

The ballast throttles the current by way of self inductance. The starter temporarily by passes the lamp ends and enables the current flow through florescent material of the tube. This action causes the start of current in fluorescent light fixture for the required glow.


What is wrong when only two of four new fluorescent bulbs will light in the 4 bulb fixture?

There might be a problem with the actual bulbs when only two of the four new fluorescent bulbs will light in the 4 bulb fixture. In some cases the ballast might be damaged or there might be an issue with the electrical connection from the bulb to the ballast.


How do you wire 347 volts ballast to 110 volt feed?

You don't. A ballast with a 347 volt input is a commercial ballast. The 347 volts comes from a 600 volt three phase four wire Y system. You can change the ballast out to a 120 volt and rewire the unit but in most cases it is cheaper to buy a completely new lighting fixture.


How do you convert to 120 volts from 277 volts?

If for some reason you really love that light fixture, you can try to find a lamp that uses a ballast that will fit your fixture. Then retro-fit your fixture with that ballast. Unless, you're an electrician, you're going to have a hard time doing that, and you'll probably end up wasting time and money. Best bet: Buy a new fixture and save your self some aggravation.Additional Information:It sounds to me like your working with florescent lighting. 277 volts is a voltage used in a commercial building with 3 phase power to operate florescent lighting. If you are trying to put one of these florescent light fixtures built for this in your home its not worth the work pulling 240 volts to the fixture and trying to calibrate a step up transformer to give you 277. It's not worth the time, effort or money. Also, it'd be pretty tacky and rigged. All you need to do is go to Home Depot or Lowe's, and buy a florescent fixture that takes 120v. Inside these fixtures is something called a ballast that steps the voltage up to what it needs to run. Although you can buy a ballast separately, I wouldn't try to install one in your fixture, as I believe they only produce about 166v or something like that.

How much power does a fluorescent fixture use with no tubes installed For example a switched on 8' fixture with a single tube with an old ballast.?

Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....


If a light fixture has a change in voltage from 277v to 120v does the ballast need to be changed?

The impedence of the ballast is system voltage dependent to allow required current to pass through the light fixture. If system voltage changes, the current passing through the light fixture changes, therefore to get designed output from the fixture, the ballast has to be changed.


How much electricity does a fluorescent fixture use?

Look at the ballast and there you will find an amperage that the ballast uses. Also find the voltage that the ballast uses. Use this formula to fine the wattage of the fixture. Watts = Amps x Volts.


How do you rewire a magnetic ballast F96T12 fixture to work with a new electronic ballast?

The end sockets have to be rewired. The schematic for the rewire is on the ballast label.


Is there a proper wiring diagram for a four tube and two ballast fluorescent light?

The correct connection to a ballast is found printed on the ballast label inside of the fixture.


How many amps does a 1000 watt ballast use?

To answer this question the voltage of the ballast must be stated and the type of lamp in the fixture.


How do you connect 250 watt bulb into a ballast?

If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.


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

need a universal voltage ballast 120/277 volt or a 277volt ballast


Can a T12 fluorescent bulb be replaced with a T8 bulb in a light fixture?

A T8 lamp can be retro fitted into a T12 fixture by replacing the T12 ballast with a T8 ballast. The end sockets also have to be rewired in the retrofit as the wiring from the electronic ballast to the sockets is completely different.


Can you wire a 347 volt ballast to a 120 volt fixture?

Yes, but it will not work.


How do you ground a fluorescent light ballast?

If the fluorescent lighting ballast is attached to a metal lighting fixture the grounding occurs through the metal of the fixture and the screw that holds the ballast in place. Other wise you need to add a gounding clamp or a grounding pig tail to the metal of the ballast. This would only be done in custom installations.
