The LED light tube is a modern light source

Light tubes are mainly used in G13-based fluorescent light fixtures to replace T8 fluorescent tubes. The main advantages of an LED light tube over a fluorescent tube are energy efficiency and longevity. An LED is also referred to as an LED fluorescent tube, but because the light from an LED fluorescent tube comes from LED components and, like a fluorescent tube, does not contain fluorescent material, an LED fluorescent tube is a more appropriate name for a product.
