The term "LED T5" refers to a specific type of LED lighting product, with "T5" indicating its physical shape and size. The "T" in "T5" stands for "tubular," which means these lights have a cylindrical shape. The number "5" represents the diameter of the tube in eighths of an inch. So, a T5 - sized tube has a diameter of 5/8 inches, which is approximately 16 millimeters.
When combined with "LED," it means that this T5 - shaped tube uses LED technology as the light - emitting source instead of traditional fluorescent technology. LED T5 lights offer several advantages over their fluorescent counterparts. They consume significantly less energy, often reducing electricity bills by up to 50 - 70%. They also have a longer lifespan, reducing the frequency of replacement and maintenance costs. Additionally, LED T5 lights do not contain harmful substances like mercury, which is present in fluorescent lamps, making them more environmentally friendly. They can also provide instant full - brightness illumination, unlike fluorescent lights that may take some time to reach their full brightness, especially in cold environments.
