How much does ballast replacement cost?

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.

Can a ballast be repaired?





While simply swapping burned out bulbs in an existing ballast is deemed “ballast repair” by many – and can offer advantages in longevity and energy savings – sometimes this simple “fix” is not enough.

Do you need a ballast for headlights?

No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.

How long do digital ballasts last?

For optimum efficiency, you should replace your magnetic ballast every 2-3 years. Digital ballasts last much longer, and have a consistent output over their life. They only need replacing if they stop working, which can be 10+ years.

How do I know if the ballast needs to be replaced?

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.

What causes fluorescent lights to flicker?





Blinking can also be caused by a loose connection in some of the wires inside the fixture, or by a defective ballast. It can also be caused by low temperatures (below about 50 degrees) unless you have special low-temperature tubes and low-temperature starters.

Does a ballast use electricity if no bulbs are present?

No, unlike LEDs, the fluorescent bulb itself (or rather the tube) can not use power when it burns out, however, the ballasts may use a trace of energy whether or not there is a bulb installed.

What is the life of a ballast?

12 to 15 years

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.

Do electronic ballasts use less electricity?



The amount of energy lost through an electronic ballast is significantly less than that lost through a magnetic ballast. Lights that use 39 to 175 watts of energy will lose between 14.6 and 37.6 watts of energy when used with a magnetic ballast, according to the Lawrence Berkeley National Laboratory.

How do you tell which ballast you have?

You can determine whether you have a compatible fixture in seconds. Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.

What’s the difference between digital ballast and electronic ballast?

Digital ballasts have higher output and will give almost 30% more light. They are cooler and provide better spectral output. They have adjustable wattage, which allows you to use power your grow lamp at different wattages.

How can you tell the difference between magnetic and electronic ballast?



Stand under the light or a place close to the light and point your cell phone camera at the light.

  • If you can see some strong dark strips flickering in your camera, it must be a magnetic ballast based light.
  • Otherwise it should be an electronic ballast based light.

How do I know if my ballast is T8 or T12?

If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.

Can I replace a magnetic ballast with an electronic one?

Fortunately, compatibility isn’t really an issue, as most electronic ballasts have been designed to replace existing magnetic ballasts. A preferable electronic ballast is the T8 model. This option has several advantages over the T10 and T12, including improved lighting efficiency.

Can you use LED bulbs with a ballast?



Since plug and play LEDs are compatible with ballasts, you can simply remove a fluorescent bulb and replace it with an LED. Since no additional modification or wiring is required, it’s as easy as replacing incandescent bulbs with LED bulbs in your home.

Is ballast bypass safe?

Safety risk

The most significant negative to a ballast-bypass linear LED is the risk of electric shock since the sockets carry line voltage. It’s a common practice to place a finger on the lamp pins while you are trying to install it, and this becomes a risky endeavor when using single-ended ballast-bypass lamps .

How do you bypass the ballast for LED lights?
