Best Monitor Light Bars in 2026: Tested and Ranked

A monitor light bar is the single best lighting upgrade for a home office. It clips onto the top of your screen, frees up the desk and uses asymmetric optics to light the keyboard area without bouncing glare into the monitor. These are the six we recommend in 2026, ranked by the kind of desk you have, with Amazon UK prices checked in September 2026.

How we tested

Each light bar was fitted to a 27-inch flat IPS panel, a 32-inch curved panel and a 34-inch ultrawide, then run for two weeks of daily use. We assessed glare on the monitor, coverage on the desk, colour accuracy, build quality and the ergonomics of the controls.

1. BenQ ScreenBar Halo 2: best overall

The Halo 2 does what the original does (asymmetric forward beam, no screen glare, even desk light) and adds a wireless puck and a backlight that bounces off the wall behind the monitor. £149, rated 4.7 stars from 1,259 ratings. Pros: best-in-class optics, backlight reduces eye strain in dim rooms, wireless puck, excellent build. Cons: the most expensive option here, USB-A only, and the backlight is wasted with no wall behind your screen.

2. BenQ ScreenBar: best for tighter budgets

The original ScreenBar without the puck or backlight, with touch controls on the bar itself. £89, rated 4.7 stars from more than 4,500 ratings. Same lighting quality as the Halo for about £60 less. Cons: no remote, no backlight.

3. BenQ ScreenBar Pro: best for ultrawide and wide desks

The Pro is listed with ultrawide illumination and a motion sensor. £119, rated 4.7 stars from 1,271 ratings. A good pick if you have a wide monitor or a big desk to cover.

4. Quntis 41cm wireless monitor light bar: best budget light bar

The best £40 you can spend on lighting. It offers remote and touch control, 5–100% brightness and 3000–6500K colour temperature. £39.99, rated 4.6 stars from nearly 19,000 ratings. Cons: plastic body and a fussier clip on deep-curve monitors.

5. Quntis 51cm curved monitor light bar with backlight: best budget curved-screen bar

A longer 51cm bar designed for curved monitors with a backlight and remote. £54.99, rated 4.5 stars from about 1,900 ratings. A good way to get the backlight feature without paying BenQ money.

6. Yeelight 42cm monitor light bar: best cheap touch-control bar

A 42cm bar with touch control, 78 LEDs and 1,500 lux listed output. £29.99, rated 4.4 stars from 427 ratings. The cheapest bar here we are comfortable recommending, with less refined controls and build.

How to choose the right light bar

Match the bar to your monitor: flat or gently curved screens fit any bar; deep-curve ultrawides suit the Halo or a bar designed for curved screens.
Decide if you need a backlight: worth it if you work in dim conditions or take many video calls.
Plan your power: bars run on USB-A, so a USB-C-only monitor needs a small adapter. Avoid powering it from a laptop that stays asleep.
Multi-monitor: most bars are 40–50cm, so you may need one per screen.

Frequently asked questions

Do monitor light bars actually reduce eye strain?

Indirectly, yes. The bar lights the desk in front of the monitor at a level closer to the screen, evening out contrast across your field of view. You notice it most as a reduced tired feeling at 5pm.

Why is the asymmetric beam such a big deal?

A normal lamp shining down would also bounce light into the screen, creating glare. Asymmetric optics throw light forward and downward only.

Will a light bar damage my monitor?

No. Reputable bars use sprung counterweight clips or padded designs that grip without scratching.

The bottom line

If you can afford it, buy the BenQ ScreenBar Halo 2; if you cannot, buy the original ScreenBar. If neither fits the budget, the Quntis is the sub-£50 bar we recommend without caveats. Avoid no-name £20 bars: build quality and light consistency are not worth the saving.
