BenQ ScreenBar Halo 2 LED Monitor Light Bar

The BenQ ScreenBar Halo 2 is a monitor light bar that mounts to the top edge of your display. Its 18-degree asymmetrical optical design directs light onto your desk while preventing reflections on the screen. It uses LEDs with a maximum power draw of 15 W to provide balanced illumination for long working sessions. Built-in proximity sensors turn the light on and off automatically based on your presence at the workstation, while BenQ's ASMY-Light technology spreads the light evenly to reduce eye strain caused by high contrast between your screen and the room.

The unit clips onto the monitor without requiring permanent fixtures. The clamp fits a wide range of flat and curved displays, and the housing—made from a mix of aluminium, ABS, and polycarbonate—is durable. You can adjust the settings using the included rechargeable wireless controller, which avoids the need to reach for the light itself. The device is powered via a standard USB-C connection, allowing for simple integration with monitors or external hubs.
