A Luminous USB Keyboard is a wired keyboard that connects via USB and features built-in backlighting, often with vibrant RGB or single-color illumination. This glowing feature not only enhances the keyboard’s aesthetic appeal but also improves visibility in low-light or dark environments, making typing easier and more comfortable. Popular among gamers and professionals, luminous USB keyboards often include features like anti-ghosting, programmable keys, and ergonomic designs. Combining reliable wired performance with striking illumination, they provide both functionality and style for a better user experience.
