What Does T7 Mean on a Light Bulb?

The T7 designation on a light bulb indicates the shape and size of the bulb. The “T” stands for tubular and the “7” indicates that the diameter of the bulb is 7/8 of an inch. This is a standard size for many household and commercial applications.

The T7 bulb is also sometimes referred to as a Miniature Edison Screw (MES) or simply an Edison Screw (ES).

There are a few different things that T7 on a light bulb can mean. The most common is that it is the code for the shape of the light bulb. T7 bulbs are typically smaller and more narrow than other types of light bulbs.

They also have a slightly different base than other bulbs, so they can’t be used in all fixtures. Another possibility is that T7 refers to the wattage of the bulb – 7 watts. This is a relatively low wattage, so these bulbs are often used for night lights or other applications where you don’t need a lot of light.

Finally, T7 could refer to the type of glass used in the bulb. There are several different types of glass, and each has its own benefits and drawbacks. T7 glass is usually tempered, which means it can withstand higher temperatures and is less likely to break than other types of glass.

What Size Light Bulb Do I Need

A light bulb’s size is determined by its diameter and length. The most common sizes are A19 (standard), A21 (3-way), and PAR20, PAR30, and PAR38 (flood/spot). The number following the “A” or “PAR” indicates the diameter of the bulb in eighths of an inch.

For example, an A19 bulb has a diameter of 19/8 inches (2.375 inches) and a PAR38 has a diameter of 38/8 inches (4.75 inches).
