The BenQ ScreenBar Halo is built to help reduce eye strain by giving you consistent and focused lighting. One thing to watch out for with LED lights like this is flickering, which can happen if the light isn't getting enough power. According to our research, the ScreenBar Halo needs a 5V/1.5A USB port to work at its best.
If you plug it into a laptop or a USB hub that doesn't meet these power needs, you might notice some flickering, and it won’t provide the steady light you need.
Our data shows that a simple fix is to connect the ScreenBar Halo to a USB port that meets these requirements. Many have found success using a monitor’s USB port or an external USB power adapter that's up to spec, which usually takes care of the flickering issue.
Ensuring you use a reliable USB charger or hub that can provide enough power will make sure your light shines smoothly.
Aside from flickering, the ScreenBar Halo is designed to cut down on glare and reflection, which is important for easing eye strain. It lights up your workspace with an asymmetrical design, so the light doesn't bounce directly onto your screen, avoiding those annoying reflections.
Plus, the manufacturer mentions that it emits a warm light that's gentle on the eyes, which is great if you're sitting at your desk for long periods.
So, to keep your BenQ ScreenBar Halo running smoothly and reduce eye strain, make sure it's hooked up to a good power source. A well-powered USB hub or the right power adapter not only helps prevent flickering but also lets you enjoy the thoughtful design that aims to make your desk work more visually comfortable.
