Will the ScreenBar Halo 2 fit my monitor?

BenQ says the clamp fits monitors 0.43 to 6 cm (0.17 to 2.36 in) thick, including curved monitors from 1000R to 1800R. It also works with monitors that have a bulge on the back.

Does it cause glare on my screen?

BenQ designed the front light with an asymmetric optic and an 18 degree cut-off angle so light falls on your desk, not on the screen or into your eyes.

What does the backlight do?

It lights the wall behind your monitor. That softens the contrast between a bright screen and a dark room, which BenQ says reduces eye fatigue. BenQ says its coverage is 423% wider than the first ScreenBar Halo.

The light bar runs on USB-C (5V, up to 3A, max 15W) with a 150 cm cable. A USB-C power adapter is in the box. The wireless controller has its own rechargeable battery.

Can I still use my webcam?

Yes. BenQ says the front edge won't block built-in monitor cameras, and a webcam accessory in the box lets you mount a webcam above the light bar.

What is the BenQ ScreenBar Halo 2?

The BenQ ScreenBar Halo 2 is a light bar that clamps to the top of your monitor. A front light shines down on your desk, and a backlight lights the wall behind the screen. It replaces the original ScreenBar Halo as BenQ's top monitor light. You control it with a wireless puck that sits on your desk.

What stands out

Light front and back. The tri-zone backlight softens the contrast between a bright screen and a dark room. BenQ says it covers 423% more area than the first Halo.
No glare on the screen. The front light uses an asymmetric optic with an 18 degree cut-off, so light lands on the desk instead of the display.
Fine control. Both lights have stepless brightness, and color temperature runs from 2700K to 6500K. The controller lasts up to 3 months per charge, according to BenQ.
Fits curved monitors. The clamp works on screens 0.43 to 6 cm thick and curves from 1000R to 1800R.
Smart extras. A presence sensor turns it on and off for you, and auto-dimming targets 500 lux on your desk.

Who is it for?

It's for people who work late or in dim rooms and get tired eyes from staring at a bright screen in the dark. It also suits small desks where a lamp would take up space, and curved-monitor owners who struggle to find a light bar that fits.

Skip it if your room is bright during the day and you rarely work at night. A cheaper light bar without a backlight, or no light bar at all, will do the job.

Our take

On paper, the Halo 2 covers the main reasons people buy a monitor light: even desk lighting, no screen glare, and less eye strain in a dark room. The backlight and wireless controller are what set it apart from simpler bars. The trade-off is cost, since it's premium-priced for a desk light. It makes the most sense if you spend long evenings at your desk.
