Is a monitor light bar worth it? Check your desk first

Measure the space you would actually gain

Move your existing lamp temporarily and look at what its base occupied. Would that space become useful for a notebook or keyboard, or would it simply remain empty? If the lamp sits outside your working area already, replacing it may offer little practical benefit.

A light bar changes where the lighting hardware lives. It does not remove every accessory from the setup. Consider a power cable and, where applicable, a separate control unit. Plan where those parts would sit before counting the full lamp-base footprint as reclaimed space.

Check the monitor rather than just the screen size

The top edge and rear profile are more useful compatibility clues than diagonal screen size alone. Look for a built-in camera, raised housing, unusual rear shape, or an existing webcam mount. A light must attach in the way its manufacturer intended without improvising a clamp arrangement.

For the ScreenBar Halo 2, BenQ lists a compatible monitor thickness range of 0.43–6cm for flat and curved screens. That range is only one check, not a guarantee for every monitor inside it. Compare the exact profile and other hardware against BenQ’s guidance, and ask BenQ about an unusual screen before you order.

Decide whether the desk or the room needs light

Think through an evening at your desk. Do you mostly type in front of a fixed monitor, or do you turn to paperwork, sketch on a separate surface, and read a book off to one side? A lamp that can move with those tasks may be the more practical tool.

A monitor-mounted light is a candidate for concentrated desk work with a stable screen arrangement. It is not a room-lighting replacement or a medical device. We do not promise that it will prevent headaches, treat eye symptoms, or solve every glare problem. Actual positioning and the surrounding room still matter.

What makes the Halo 2 a candidate

BenQ’s Halo 2 includes front and rear lighting and a wireless controller. Those are useful features to investigate if independent adjustment and controls within reach are important to your desk. Check the current specification for the power source and what comes in the box.

We have not measured its brightness, assessed glare on your monitor, or compared it hands-on with other light bars. Its inclusion is based on documented features and the problem it may solve. If you only need a simple task light, do not assume you need this particular feature set.

Use this decision test before checkout

First, try repositioning the lamp you already own. Second, map the screen-mounted alternative, including its cable and controls. Third, identify one concrete improvement you expect, such as recovering the surface used by a lamp base. If the improvement is hard to describe, postpone the purchase.

If you proceed, confirm compatibility with the exact monitor, check the current seller and return terms, and keep packaging while evaluating the setup. During ordinary use, look for unwanted reflections, blocked camera views, awkward controls, and cables that interfere with screen movement. A worthwhile accessory should make the routine simpler rather than require a new workaround.
