An LED tube light diffuser is a cover, typically made of acrylic, polycarbonate, or glass, that is placed over the LED tube to evenly distribute the light it emits. The diffuser helps soften the light output, eliminating the harsh glare that can occur with direct LED lighting. It ensures that light is dispersed uniformly, creating a more comfortable and visually appealing illumination. https://xtruline.com/led-tube-light-diffuser-a-comprehensive-guide/
