Do you need a ballast for LED lights?

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.

Can I put LED bulbs in a fluorescent fixture?

You may already have fluorescent tube lights in your home or place of business, and youre wondering whether you can simply insert LED tubes into those fixtures or whether youll need to replace them with LED-compatible fixtures. Good news: you can use LED tubes in your existing fixtures!

Can you replace fluorescent lights with LED?

Yes, you can convert a fluorescent fixture to LED by swapping out the fluorescent tubes for LED ones or for fixtures that have LEDs built right in. If you only want to change the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes.
What does a ballast do for LED?
Lamps do not have regulators and can draw too much or too little power on their own. A ballast ensures that the amount of current being provided to the lamp does not exceed the specification of the light. The ballast also provides sufficient voltage to start the lamps.

Although the functions of ballasts and drivers are quite similar, most documentation prefers to refer to drivers as being associated with LED lamps and ballasts as being associated with other conventional light sources. Fluorescent lights use ballasts, whereas LED lights use drivers.
Is it safe to bypass a ballast?
Since the sockets for a ballast-bypass linear LED carry line voltage, the risk of electric shock is the most significant drawback. When using single-ended ballast-bypass lamps, it becomes dangerous to install the lamp with your finger on the pins.
Can a ballast compatible LED be used without a ballast?
As long as you have a T8 LED tube that is ONLY ballast dependent, you are required to keep purchasing and replacing ballasts because the T8 LED tube wont function without it.
How do I know if my ballast is compatible with LED?
Turn the light on, then take a photo of the fixture with 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, and you can tell in seconds whether you have a compatible fixture.
Will LED bulbs work if ballast is bad?
Unlike fluorescent tubes, which still use energy when using direct fit LEDs, LEDs dont need a ballast to regulate current, making them significantly more energy-efficient than fluorescent bulbs in their own right.
Can I bypass the ballast for LED lights?
Since most T8 LED tubes dont require a ballast and LED lights operate on low DC voltage, installing a T8 LED tube light will require a ballast bypass unless you select a ballast-compatible T8 LED tube.1 Sept 2020

Plug and play LEDs are compatible with ballasts, so you can easily swap out a fluorescent bulb for an LED by simply removing the old one. Plug and play LED tubes are similar to fluorescent bulbs in shape and connection to the fixture.

What is T8 vs T12?

T8 LED tubes wont fall out if you try to install them in a T12 fixture—theyll fit just fine. The main distinction between T8 and T12 tubes is the tubes diameter: T12 tubes are 1.5 in diameter, while T8s are just one inch. All other things—socket sizes, lengths, and distance between pins—are the same.
