Looking for an answer to the question: Will a t8 ballast work with t12 bulbs? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Will a t8 ballast work with t12 bulbs?

To test the fluorescent light ballast, turn off the circuit breaker for the fluorescent fixture, and remove the fixture’s lens cover. Afterward, remove the bulbs from the fixture. Next, take the ballast cover from the fixture, and replace the ballast if it appears leaking, burned or swollen.

The T12 fixtures tended to use magnetic ballasts. T8 fluorescent bulbs are just as bright as the T12 – and much more economical. The T8 models cost almost half of the T12. If the room has less than 12 feet of height, a T8 can illuminate the space adequately.

The T8 light bulb puts out a little bit more light than the T12 light bulb, but once again, the difference is incredibly small. Light output is measured in lumens, and the T8 bulb producers approximately 2600 lumens, while the T12 bulb produces approximately 2520 lumens.

How do I know what type of ballast I 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.

A T8 ballast is generally not compatible with a T5 linear fluorescent lamp. … The pin sockets will only line up and complete a circuit in a correctly sized ballast. The exact design of each ballast differs across manufacturers. There are a few ballasts which can be rewired for T5 or T8 bulbs.

Will a T5 bulb fit in a T12 fixture?

For some applications, one T5 bulb can replace two T12 bulbs, providing even greater energy savings (a process called “de-lamping.”) The typical T12 four-lamp fixture uses 172 watts of power between the lamps and ballast.

Do T8 LED bulbs need a ballast?

Most T8 LED bulbs do not need a ballast. The only type of LED tube that requires a ballast is plug-and-play. Used as direct replacements for fluorescent tubes, plug-and-play LED tube lights install without fixture rewiring, and operate off the existing fluorescent ballast.

Which is better T8 or T12 bulbs?

The smaller the lamps the more energy efficient they are. T8 bulbs use about 35% less electricity to produce the same amount of light as a T12. T5 bulbs use about 45% less energy than T12s.

Are all T12 ballasts the same?

There are two lamp families that work with a ballast: fluorescent and HID. And there are two types of ballasts in each family: magnetic and electronic. … 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.

Which is better T8 or T5?
