BenQ publishes the same 85 × 50 cm coverage at 500 lux for these two models. Pro is the simpler shortlist when front task lighting is the job and rear lighting is unnecessary.
Skip it if: You need Halo 2’s rear light or wireless controller, or the clamp does not suit your monitor.
Find on Amazon Check manufacturer details ↗Its extra reason to buy is the front/rear lighting arrangement and separate wireless controller. Buy those functions deliberately rather than assuming a larger published task-light footprint.
Skip it if: You only want front task light, have nowhere useful for the controller, or cannot supply the documented power.
Find on Amazon Check manufacturer details ↗Consider a monitor light bar when the screen stays in a fixed place and avoiding a lamp base is a priority. Consider a conventional desk lamp when you need to move light between a notebook, craft area, or another position away from the monitor. A supported clamp lamp can be another way to preserve surface space.
Within the light-bar shortlist, investigate Halo 2 if its rear lighting and separate wireless controller are features you want. Investigate ScreenBar Pro when monitor-mounted task lighting and its documented automatic adjustment match the job. Neither choice replaces checking the actual screen housing, power arrangement, and workspace.
Start by identifying where the light needs to land. A beautifully tidy fixture is not useful if the work area you need to see remains awkwardly lit.
| Question | Monitor light bar | Desk or clamp lamp |
|---|---|---|
| Where does it live? | On a compatible screen housing | On the surface or a supported clamp point |
| What is the typical use? | Lighting the working area near the monitor | A separate or movable reading/work area |
| What takes up space? | Fixture, cable, and any separate controls | Base or clamp, arm, cable, and movement area |
| What can get in the way? | Webcam and screen shape | Documents, shelves, or other desk objects |
| What should you test? | Fit and light direction in the actual setup | Reach and useful coverage in normal positions |
Place the notebook or other task material where it normally sits. Consider whether that area changes between typing, reading, and video calls. A fixed light near the display can suit a stable arrangement; a task that moves around the room may need a different approach.
Include the room’s existing light in the decision. If a window, ceiling fixture, or another lamp already does part of the job, identify the remaining problem precisely. Buying a more elaborate device is not the same as improving the whole lighting arrangement.
This is a practical buying comparison. We are not measuring eye strain, assigning health benefits, or presenting the manufacturer’s performance claims as our own test results. The useful question here is whether the format and controls fit how you work.
The two specification pages publish an 85 × 50 cm coverage area at 500 lux. Halo 2 adds a reason to consider rear illumination and a wireless controller; the listed front coverage figure does not establish an advantage over Pro. Decide which of those extra functions you will use.
BenQ lists maximum input consumption of 15 W for Halo 2 and 8.5 W for Pro. Those maxima help you plan a suitable supply, but they are not measurements of typical energy use in your room. The Halo 2 controller is listed as 7.4 × 7.4 cm across its footprint, so include that small object in your surface plan.
| Check | Halo 2 | Pro |
|---|---|---|
| Coverage at 500 lux | 85 × 50 cm | 85 × 50 cm |
| Maximum power consumption | 15 W | 8.5 W |
| Listed monitor thickness | 0.43–6 cm | 0.43–6.5 cm |
| Power connector | USB Type-C | USB Type-C |
BenQ describes Halo 2 with front and rear lighting plus a wireless controller. The Pro information describes monitor-mounted task lighting with automatic adjustment. The table highlights those reasons to investigate; it is not a claim that we have compared brightness or tested either fixture.
| Decision | ScreenBar Halo 2 | ScreenBar Pro |
|---|---|---|
| Feature to investigate | Front/rear lighting and wireless control | Task lighting and automatic adjustment |
| Buying priority | You specifically want the controller/rear-light arrangement | You are focused on the documented desk-lighting setup |
| Still check | Housing fit, webcam, power, and controller position | Housing fit, webcam, power, and adjustment controls |
Look at the screen from above and behind, not only from the front. Note housing shape, thickness, built-in cameras, and where an external webcam attaches. Compare those details with the exact light’s documented compatibility and accessory information.
A common planning mistake is to assess the light and webcam separately, then discover that both want the same space. Work through the complete arrangement, including the webcam cable, any bracket, and the light’s power connection. Do not assume that a generic accessory is suitable for every fixture.
If the display is curved or has an unusual rear enclosure, check the manufacturer’s specific guidance. A broad description such as compatible with curved screens does not settle every fit question about a particular monitor.
Decide where you want to change the light settings. A separate controller is attractive only if you have a useful place for it and will use it. Controls on or near the fixture may suit a different routine. Picture reaching them while your normal equipment is on the desk.
Next, consider how often the workspace changes. If you pack away a laptop every evening, a fixed monitor-mounted fixture may not address the mobile part of your day. If you read papers away from the screen, a movable lamp may be the more flexible purchase even when it has a larger footprint.
Make a short checklist before the item arrives so the evaluation follows your actual tasks. Follow installation instructions and the seller’s current return conditions. Compare the arrangement with what you already own rather than assuming a new device must be an improvement.
Does a monitor light replace all room lighting? Plan it around the task area and the room as a whole. A single fixture should not be assumed to solve every lighting need.
Is a separate controller always better? Only if that control arrangement suits your workspace. Count it as another object that needs an accessible position.
Which model is the overall winner? There is no measured winner in this guide. Choose by the useful feature set, documented fit, and current total purchase cost.
Choose the lighting format first. Then compare Halo 2 and Pro only if a monitor-mounted solution suits the workspace. Paying for a feature you do not need is less useful than selecting an arrangement you will maintain and use.
