No screen glare: The light bar directs illumination to the desk rather than the screen, and the asymmetric optical design prevents brightness on the monitor itself. Memory function and dimming: The Light Bar monitor offers warm white, natural white and white colour temperatures, and remembers the last colour temperature and brightness setting. Brightness is dimmable from 10% to 100%. Simple installation: No screws or tape are required. The LED screen light bar works with computer USB ports, portable power supplies, or any DC5V USB powered device. It fits monitors with a thickness from 0.5 cm to 1.2 cm. Save desk space: The computer screen lamp sits firmly above the monitor, making it ideal for limited workspaces in the office or home and helps keep valuable desk space . Use scenarios: Home office or study desk: Mount above the monitor to provide focused desk lighting for keyboards and documents without creating glare on the screen. Dorm room or shared workspace: Powered by a USB power bank or USB charger, easy to relocate between setups. Late night work or editing tasks: Choose from three colour temperatures and adjust brightness to suit ambient lighting and task requirements.
