What does G13 mean in lighting?

When it comes to lighting, you may have come across the term G13. But what exactly does it mean? In short, G13 refers to a specific type of lamp base that is common in fluorescent lighting fixtures.


The "G" in G13 stands for "bi-pin", which refers to the two metal pins on the base of the lamp that connect it to the fixture. The "13" in G13 refers to the distance between those pins, which is 13 millimeters.


G13 is a widely used lamp base for linear fluorescent tubes, which are commonly found in a range of settings, from offices and schools to retail stores and warehouses. These tubes are designed to fit into fixtures with two sockets, one at either end of the tube.


If you're in the market for new fluorescent lighting, it's important to keep in mind the type of lamp base you need. G13 is just one of several options out there, so be sure to check the specifications of any fixtures you're considering to ensure compatibility.


In addition to G13, other common lamp bases you may come across include G5 (used for smaller fluorescent tubes) and E26 (used for many types of incandescent and LED bulbs).


Understanding the different types of lamp bases can help you choose the right lighting for your needs and ensure that your fixtures operate safely and efficiently. So the next time you see the term G13 in reference to lighting, you'll know exactly what it means.
