One of the reasons why fluorescent lighting systems are so common is because they are very easy to work with and extremely easy to understand when it comes to parts. The T-5 sockets and T-5 lamps will work with any T-5 fluorescent system, which takes the challenge out of having to match up parts from a system that may not have universal or consistent nomenclature methods.
Understanding the T-5 Designation
The designation of T-5 sockets is very simple. The T indicates the shape of the tube or the lamp that is used with the socket and in the system. In this case the “T” indicated a tubular lamp.
The designation 5 is a measurement of the number of eights of an inch in the diameter of the lamp. So, in the case of a T-5 socket and T-5 lamp the diameter of the lamp, and consequently with a consistent size of base, will be five eights of an inch.
As the T-5 lamp has a small diameter, it requires T-5 sockets with an equally small diameter to allow the pins from the lamp to plug into the socket. This size of lamp and socket are known as a miniature bi-pin base since there are two pins.
Sockets and Design
There are several different types of miniature bi-pin T-5 sockets to choose from. Depending on the T-5 fluorescent system you are designing, or need replacement parts for, it is important to know the specifics of the system.
The mount options for the T-5 sockets are important to consider. Some will be constructed as tapped or rivet options. There are also some designs that are snap in models and those that slide into place and they can be tall or short or accommodate different fixtures.
You will also need to check if the fluorescent system uses a programmed start ballast as this will require a specific type of T-5 sockets, which may also be called lamp holders. Choosing a shunted or non-shunted socket, shunted are typically used for instant start ballasts and non-shunted for the programmed ballasts, will also be essential to get the right part.
For anyone using T-5 sockets on a regular basis, buying in bulk is always the best option. This not only gives you a lower per unit price, but it also helps to ensure the parts needed are always available.
