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.
What is better T8 or T12 bulbs?
The main difference between T8 and T12 bulbs is that T8 bulbs have a diameter of 1.5 inches, whereas T12 bulbs have a diameter of 1 inch. T8 bulbs are a better choice than T 12 bulbs. This can be easily proved. T8 bulbs have a better color rendering index as well as high efficacy.
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.
Are T12 bulbs being discontinued?
In effect since July 2012, the legislation eliminates nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and almost all standard halogen PAR38, PAR30 and PAR20 lamps from the market. T12 technology is over 80 years old.
Can I replace a T12 ballast with a T8?
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.
Can you put LED lights in a fluorescent fixture?
You have fluorescent tube lights in your home or business already, and you’re wondering if you can pop LED tubes in these fixtures or if you’ll need to change out the fixtures for something designed for LED. Good news! You can use LED tubes in your existing fixtures!
What does T8 or T12 mean?
A T12 lamp (on the left in the figure below) is therefore twelve-eighths of an inch, or one-and-one-half inches (3.81 cm), in diameter. A T8 lamp (on the right in the figure below) is eight-eighths of an inch, or one inch (2.54 cm), in diameter.
Do I need to remove the ballast to use an LED bulb?
An LED light does not require a ballast because it uses a component called a “driver” to regulate the power going into the bulb.
Can I replace fluorescent tube with LED?
Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.
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.
How do you convert a T12 fluorescent bulb 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.
Are T8 bulbs being phased out?
Out With the Old, In With the LED
The Ecodesign Regulation set a schedule to eliminate integrally-ballasted compact fluorescent (CFLi) and T12 linear fluorescent (LFL) lamps in September 2021, and most T8 LFLs in September 2023.
Are fluorescent lights going away?
US Department of Energy (DOE) regulations began phasing out various sizes of commercial fluorescent light bulbs in 2012. About all you can get today is the fluorescent workhorse of commercial lighting—the T81 bulb. By January 26, 2018 even T8s will be banned to align with new DOE energy efficiency standards.
What light bulbs are being discontinued?
From this date onwards, some popular bulbs will no longer be available on the market. For example, the production of T8 fluorescent tubes with lengths of 600 mm, 1,200 mm as well as 1,500 mm will be discontinued. In addition, pin-base lamps for G4, GY6. 35 and G9 sockets will be phased out.
