Sizes, shapes, and types of bases for fluorescent lights
The fixture is the first thing you need to look at when buying a new or replacement fluorescent bulb. Which kind of electrical socket will the bulb fit into? Most of the time, fluorescent bulbs have bi-pin (two-pin) or single-pin bases. There may be recessed double contacts on some. Make sure you know which base you have when searching so that your bulb will fit correctly.
Determine what shape of bulb you need. Is your fixture U-shaped, circular, or linear? During the selection process, you will save time if you are aware of the required shape. Linear (tubular) fluorescent lights are used in the majority of facilities; They have a straight shape and are easy to use. They are the type of fluorescent light that is used the most, and they are likely what you will be looking for.
To create a specific atmosphere or style, some businesses choose to use bulbs that have a more unusual shape, such as a circle or U-Bend. These are more popular in establishments with personality and ambiance, such as hotels and restaurants.
Additionally, you will want to limit your search based on the size of the fluorescent tubes, and measuring fluorescent tubes is fairly simple. To begin, you will need to note the diameter, also known as its circumference. This is indicated by a number, like T8 or T12. Tubular is denoted by the letter "T," and the number indicates the diameter in 1/8" increments. As a result, there are eight 1/8" increments in a T8 bulb with a diameter of 1" Also, pay attention to how long your lamp is; The length of a fluorescent bulb can reach up to 96".
