If you spend hours in front of a monitor, poor desk lighting is quietly wrecking your eyes. Overhead lights create glare on your screen. Desk lamps eat up surface space. Monitor light bars solve both problems — they clip directly onto your monitor, shine light downward onto your desk, and keep your screen completely glare-free.
We compared the 5 best monitor light bars on Amazon across price, lighting quality, features, and build to help you pick the right one.

5. BenQ ScreenBar Halo — Best Premium
The BenQ ScreenBar Halo takes everything that makes the ScreenBar great and adds two premium upgrades: a rear-facing ambient LED glow for bias lighting and a wireless dial controller that sits on your desk. If you want the ultimate monitor lighting setup, this is it.
