Halo

A light bar that sits on top of a monitor and lights the desk, not the screen. No glare on the display, a warm-to-cool color range and a wireless dial on the desk to set it.

$89

A desk light that sits on top of the monitor instead of beside it. Halo throws an asymmetric beam down and forward onto the desk, so it lights your notes and keyboard without putting glare on the screen. A round wireless dial on the desk sets brightness and color temperature, so you never reach up to the bar.

We replaced our desk lamps with it for a month. On the desk surface it measured up to 500 lux, plenty for reading paper; at 2700 K in the evening the room feels like lamplight, at 6500 K in the morning it reads like daylight. The whole month is in our monitor light bar review.

Setting the light

Stepless dimming, from a faint glow to 500 lux
Color temperature from warm 2700 K to cool 6500 K
An auto-dimming sensor adjusts the output as daylight in the room changes

Mounting

Fits monitors 0.4 to 1.2 in thick, flat or curved
17.7 in long, a little shorter than the top edge of a 24″ screen
Powered over USB-C at 5 V, from the monitor’s USB port or a charger

Worth checking

A webcam clipped to the top of the monitor competes for the same spot; most fit beside the bar on screens of 27″ and up. A spare USB-C port on Hub 8-in-1 can power it. Covered by our 2-year warranty.
