How do I know if a ballast is compatible?
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.
Are fluorescent ballasts interchangeable?
When considering a ballast for your lamp, make sure they have corresponding ANSI (American National Standards Institute) codes. Matching ANSI codes guarantees that the ballast you chose can be used with your lamp. However, ballasts are often compatible with more than one lamp, and vice versa.
How do I know which ballast to buy?
Quote from the video:
Quote from Youtube video: The only things that matter when you're replacing a ballast are we're number one the number of bulbs number two the type of bulbs number three the voltage.
Can I replace a T12 ballast with a T8 ballast?
The easiest and lowest price option to replace a T12 is a T8 linear fluorescent. They have become the go-to option for pre-existing T12s. If you still have magnetic ballasts, switching to a T8 will require a ballast swap. Another option is to move forward with an LED retrofit.
How do I know if I have a T8 or T12 ballast?
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.
What’s the difference between T8 and T12 ballast?
The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
What do the numbers mean on a ballast?
The most common types are T12, T8, and T5. The T stands for tubular and the number indicates the diameter in 1/8 of an inch. Lamp diameter is determined by ballast type. A fixture with a T12 ballast must use a T12 bulb. A fixture with a T8 ballast must use a T8 bulb, etc.
What is the difference between magnetic and electronic ballast?
Magnetic ballasts work at a frequency of around 60 Hz, whereas electronic ballasts work at an increased frequency of around 20,000 Hz. This is why fluorescent lamps using electronic ballasts do not flicker or emit any buzzing sounds. Electronic ballasts are also quite smaller in size and weight.
Can I replace a magnetic ballast with an electronic ballast?
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 I put a T8 ballast in a T12 fixture?
As far as safety is concerned, you can exchange them. 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 I use T8 in place of T12?
T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes. In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.
How do you convert T12 to T8?

Quote from Youtube video: And just touch the two little pins on the end of the light bulbs that's all you need just need to be wired.
How do I convert T12 fluorescent to LED?
If you’re converting your existing T12 lamps to LED, you have six options to choose from:
- Install ballast-bypass linear LED lamps. …
- Install plug-and-play magnetic and electronic ballast-compatible linear LEDs. …
- Install electronic ballast-compatible linear LEDs and a new electronic ballast.

How many types of ballasts are there?
And there are two types of ballasts in each family: magnetic and electronic. Magnetic ballasts are the older ballast technology. For the fluorescent family, both T12 linear fluorescents and two-pin CFLs use magnetic ballasts. For HIDs, some metal halides and HPS lamps use magnetic ballasts.
Can you use a 2 lamp ballast for 4 lamps?
A 4 lamp fixture with two rapid start ballasts can be replaced with one 4 lamp instant start ballast. As seen below, connecting the 4 lamp instant start ballast to the four lamps can be a bit confusing. This is because the wire colors on the ballast and the lampholders do not match up on two of the connections.
How do you change a ballast without turning off power?
Remove the wire nut from one of the power wires and carefully strip about 1/2 inch of insulation from the end, making sure not to touch the end. Hold the ballast wire next to this wire with the stripped ends parallel but not touching. Quickly slip on the wire nut and screw onto the ends.
How do you know when a fluorescent ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering. …
- Buzzing. …
- Delayed start. …
- Low output. …
- Inconsistent lighting levels. …
- Switch to an electronic ballast, keep lamp. …
- Switch to an electronic ballast, switch to a T8 fluorescent.
Why won’t my fluorescent light turn on all the way?
If a fluorescent tube neither lights nor flickers when switched on, first check to see that the fixture is plugged in and that no fuse has blown or circuit breaker has tripped. If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side.
