What is a T8 fluorescent tube?
The largest category of tube light in widely-available use, T8 tube lights measure 26mm in diameter and are often used for lighting large, wide-open spaces. They’re normally seen in supermarkets, warehouses, garages and offices, although they’re suitable for smaller environments that need plenty of light too.
What is the difference between T8 and T12 fixtures?
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 size is T8 tube?
1-inch diameter
T8s are 1-inch diameter fluorescent tubes, and they are the most prevalent of all fluorescent tubes.
How do I identify a T8 bulb?
Fluorescent tube shape Linear fluorescent lamps typically include a “T” in the shape abbreviation with a number following it. This “T” stands for tube and the number that follows is the diameter of the tube. That number is divided into 8 to translate into inches. So a T8 has a one inch diameter.
What size is a T8 fluorescent tube?
Are all T8 bulbs LED?
LED Linear Tube Options. There are three primary types of LED T8s on the market suitable for retrofits and one type that is a combination of two types. Primarily they are differentiated by how they interact with existing fluorescent ballasts. All fluorescent tubes need ballasts to operate, but not all LEDs do.

Will a T8 lamp work in a T12 fixture?
In terms of physical compatibility, both T8 and T12 lamps use the same G13 bi-pin base, so as long as they are the same length (e.g. 4-ft), a T8 lamp will physically fit inside a T12 fixture.
