The BenQ ScreenBar is a clip-on LED lamp, powered via USB, that mounts above the monitor to illuminate the desk surface without causing glare on the screen. It uses dual LEDs with excellent color performance (CRI≥95, Rf≥96), offers adjustable brightness and color temperature (approximately 2700K–6500K), automatic brightness adjustment based on the ambient environment, flicker-free output, and asymmetric optics to prevent screen reflection.

The standard power input is 5V via USB (≈1.3A) with a maximum power consumption of around 6.5W. Materials include aluminum alloy and PC/ABS. Typically, the package includes the lamp, the clip/monitor mount, the USB cable, and the controller, depending on the region.
