Full Review
The BenQ ScreenBar Halo is the most complete monitor lighting solution you can buy without going custom. It does what every other monitor light does — illuminate your desk without hitting your screen — but adds a rear-facing light that solves a problem most people don’t know they have.
The Backlight Is the Whole Point
When you’re working in a dark room, your eyes constantly adjust between a 400-nit screen and a black wall. That’s fatiguing in a way that’s hard to name until it’s gone. The ScreenBar Halo’s rear light creates a soft glow behind your monitor that bridges that contrast gap. After a few days with it, going back to a bare wall feels genuinely worse. This isn’t a gimmick — it’s the reason to spend the extra money over the standard ScreenBar.
Lighting Quality
With a CRI of 95+, colors look accurate and neutral. The front light runs from 2700K (warm) to 6500K (cool daylight), giving you flexibility from late-night work sessions to afternoon design reviews. The asymmetric lens design keeps light off the screen itself — no glare, no reflections. At 500 lux measured at 50cm, it’s bright enough to replace a desk lamp entirely.
Wireless Controller
The dial controller sits on your desk and connects wirelessly to the light bar. It handles brightness, color temperature, and switching between front-only, rear-only, and both modes. It’s well-machined and responsive. The only catch: the controller needs its own USB connection, which BenQ addresses with an included USB hub. Not a dealbreaker, but worth knowing if your ports are already maxed out.
Build Quality and Setup
The clip mechanism is solid and works on flat monitors down to a quarter-inch bezel, and curved monitors at 1000R or tighter. Setup takes about three minutes. The bar itself is 18.7 inches — long enough to cover most 27–34” monitors, though a 38” ultrawide may leave the edges dimmer than the center.
Who Should Buy This
Buy the ScreenBar Halo if you work in a dark or semi-dark room for long sessions and want to stop leaving sessions with tired eyes. It’s also the right call for designers and photographers where color accuracy matters. If you work in a bright, naturally lit room or just need basic task lighting, the BenQ ScreenBar Plus saves $80 and covers the basics. At $179, the Halo is a luxury — but it’s one that actually changes how working at a desk feels.
