Fluorescent tubes are measured in eighths of an inch. A T8 has a one inch (8/8 inch) diameter, a T5 has a 5/8 inch diameter, and a T12 is a 12/8 inch (1.5 inch) in diameter.
Does the length of a fluorescent tube include the pins?
For length it is imperative to measure your tube to the end of the tube including the pins. Sometimes it is easier to use a tape measure than a small ruler.

Will a T8 fit in a T12 fixture?
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 I know if I have 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.
What is T5 fluorescent tubes?
A T5 is a type of fluorescent tube. It differs from a T12 and a T8 in its diameter. All T5s are 5/8ths of an inch (T8s are exactly 1inch thick and T12s are 12/8ths or 1.5 inches thick). T5s are 16mm in diameter making them the thinnest fluorescent tube out of the three.
How are round fluorescent bulbs measured?
Circline bulbs are rated based on the diameter of the circle, measured in inches, and the T value, which is the diameter of the tube itself measured in eighths of an inch. For example, a FC15T9 circline light has a 16-inch diameter and a bulb that is 9/8-inch thick.

What is the difference between T5 and T8 tubes?
The major physical difference between T5 and T8 light bulbs is the length and diameter of the tube itself. The T5 tends to be slightly shorter than the T8 tube, and is significantly smaller in diameter. This factor is important to consider when looking at your fixture, because the two tubes are not interchangeable.
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.
What is the difference between T8 T10 and T12 fluorescent tubes?
Basically, T8 = 1 inch diameter, T10 = 1.25″, and T12 = 1.5″ diameter. Measure across one of the ends of the bulb you are replacing to see what yours is. In almost all cases, unless you have an extremely tight space, any size will work in any application. 4 of 4 found this helpful.
