What is the power factor of the ballast?

The power factor for that lamp and ballast combination is 18w / 30VA, which equals 0.6, and is considered to be low. NOTE: Power factor is often confused with Ballast Factor, which compares the lumen output of a lamp and ballast combination to that of a reference ballast rated at 1.0.

How do you calculate ballast loss?

A ballast factor is a number, typically between 0.70 and 1.2, that tells you how much light a lamp will emit with that ballast. So how do you get that number? Ballast factor is calculated by dividing the lumen output of a lamp-ballast combination by the lumen output of the same lamp(s) on a reference ballast.

Is it the ballast or the bulb?

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. Without the ballast, a fluorescent bulb would attach directly to 120-volt current and quickly burn out the bulb.

What is a light ballast?

In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.

How long does a ballast last?

According to the Certified Ballast Manufacturers Association, the average magnetic ballast lasts about 75,000 hours, or 12 to 15 years with normal use. The optimum economic life of a fluorescent lighting system with magnetic ballasts is usually about 15 years.

How much does it cost to replace a ballast?

A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably – for about 5 minutes work on each light fixture.

How do you know when ballast is bad?

If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:

1. Flickering.
2. Buzzing.
3. Delayed start.
4. Low output.
5. Inconsistent lighting levels.
6. Switch to an electronic ballast, keep lamp.
7. Switch to an electronic ballast, switch to a T8 fluorescent.

Do you need to be an electrician to change a ballast?

Yes. As a matter of fact, you do need a lock out tag out device in place for changing a ballast. ‘An electrician is replacing the ballast on a fluorescent light. The electrician uses the light switch on the wall to de-energize the florescent light.

How hard is it to replace a ballast?

A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly. You can get a new ballast at a hardware store or home center and install it in about 10 minutes.

Can you fix a ballast?

If you can change out a light switch or outlet you can definitely replace an old ballast that doesn’t work. As I said in the beginning, you’ll save yourself $75 to $90 doing this fix yourself.

How do you bypass a ballast?

How to Bypass a Ballast

1. Turn off the power. Flipping the light switch to the “off” position does not necessarily end the flow of electricity.
2. Locate your ballast.
3. Cut the hot and neutral wires.
4. Cut the socket lead wires.
5. Remove the ballast.
6. Connect the input wires to the output wires.

What to do with the yellow wires on a ballast?

you would normally have the yellow connected to one end of a bulb and the other end will be connected to either a blue or a red wire . it is basically one half of the source power circuit, yellow on one end, and either blue or red to the other end . The two wires provide the source power to light a bulb.

What causes a light fixture to stop working?

Chances are, your lights have stopped working because of one these four common reasons: The light fixture was unplugged. The light bulbs burnt out. The circuit breaker or GFI got tripped.

Why are my new fluorescent bulbs not working?

A dead fluorescent can be caused by lack of electrical power (tripped breaker or blown fuse), a dead or dying ballast, a dead starter or a dead bulb(s). Check for power first… then the starter (if applicable) and then the bulbs. When all else fails, the ballast should be replaced.

Why do my lights take a second to turn on?

Causes of a Light Switch Delay The light switch is getting worn out and needs replacing. The internal contacts can break down over time due to arcing.

Why does my fluorescent light take a long time to come on?

Most fluorescent light fixtures also have a component called a ballast, which controls the current through the fixture. If the ballast is malfunctioning, it too can cause the light to take a while to turn on. But ballasts are very expensive to replace and they malfunction far more seldom than tubes and starters.

What happens if you put a T12 bulb in a T8 fixture?

If you place T12 tubes in a fixture with a T8 ballast, you will wear out the ballast and have to replace it. If you place T8 tubes in a fixture with a T12 ballast, then the tubes will have a shorter life due to a higher current through the tube.

Can you replace a T12 with a T8?

yes you can change from T12 to T8, Just change the light, and you are done.

What happens if you don’t bypass the ballast?

The most significant negative to bypassing the ballast with a linear LED – once the ballast burns out – is the risk of electric shock since the sockets carry line voltage.
