Design & Build
The ScreenBar Halo 2 clamps onto the top edge of your monitor with a weighted, spring-loaded cradle that grips securely without a single screw or piece of tape. It fits flat and curved panels alike, and because it draws power over USB, there is no extra wall wart cluttering your desk. The standout feature remains the wireless controller: a rotary puck that sits within arm’s reach and lets you adjust brightness and color temperature without fumbling behind the display. A backlight glow softens the contrast between the bright bar and the dark wall behind it, and the motion sensor wakes the light as you sit down. Build quality feels appropriately premium, with a matte finish that resists fingerprints.
Performance
Where the Halo 2 earns its keep is light quality. The asymmetrical optical design throws illumination onto your desk and keyboard while keeping it off the screen, so there is no washed-out glare on the panel. Color temperature ranges from warm amber for late-night sessions to a crisp daylight white for focused work, and the auto-dimming mode reads ambient room light to hold a comfortable level. Compared to the simpler BenQ ScreenBar and the Quntis alternatives, the Halo 2’s motion sensor and wireless puck make it the most convenient of the bunch, though the standard ScreenBar and Quntis RGB bars deliver strong value if you do not need every extra. For anyone who games or works in a dim room, the reduction in eye fatigue is immediately noticeable.
Pros & Cons
- Zero screen glare thanks to the asymmetrical optical design.
- Wireless rotary controller for effortless brightness and temperature tweaks.
- Space-saving clamp that needs no desk footprint and fits curved monitors.
- Auto-dimming and motion sensor that adapt to your room.
- Premium price compared to Quntis and entry BenQ bars.
- No RGB accent lighting if you want a flashier gamer aesthetic.
Alternatives to Consider
If the Halo 2’s price gives you pause, the standard BenQ ScreenBar delivers the same core glare-free lighting with auto-dimming at a lower cost, minus the wireless puck. Gamers who want color should look at the Quntis RGB Pro+ or the curved-friendly Quntis 15-mode bars, which add backlighting for ultrawide screens. The BenQ ScreenBar Pro splits the difference with USB-C and a motion sensor for a slightly lower entry point.
Frequently Asked Questions
Does the ScreenBar Halo 2 fit a curved monitor?
Yes. The flexible clamp is designed to sit securely on both flat and curved panels, including ultrawide displays, without blocking the top of the screen.
How is it powered?
It draws power over USB from your monitor, laptop, or a USB hub. There is no separate power adapter, which keeps your desk clean.
Will it cause glare on my screen?
No. The asymmetrical optics direct light down onto your desk and keyboard while keeping it off the display, which is the whole point of a light bar over a lamp.
Is the wireless controller necessary?
It is a convenience, not a requirement, but it is genuinely useful. Adjusting brightness from a puck on your desk beats reaching behind the monitor every time.
Verdict
The BenQ ScreenBar Halo 2 is the most polished monitor light bar you can buy, and for gamers and remote workers who log long hours in dim rooms, the eye-strain relief alone justifies the investment. If budget is tight, the standard ScreenBar or a Quntis RGB bar will still improve your setup dramatically, but the Halo 2’s wireless control and backlight glow make it our top pick.
