The BenQ ScreenBar Halo 2 is the upgrade that changes how a desk feels to work at. Instead of standing a lamp on the surface — where it eats space and throws glare across your monitor — the bar clamps to the top edge of the screen and points down and forward. Its asymmetric optics are the trick: the beam falls on your keyboard, notes, and desk while none of it hits the panel, so you get bright task light with zero screen reflections.
It is the priciest pick here, and being monitor-mounted, it lights the area in front of the screen rather than reaching across the room like a swing-arm. For a screen-first working desk — especially one where you review art, photos, or color on-screen and still handle paper — it is the most refined lighting you can buy.
Our Pick
The desk light that clears your surface and kills screen glare in one move. It clamps to the top of your monitor, casts an even pool of light onto the desk in front of you, and never bounces reflections back into the screen. Asymmetric optics, auto-dimming to match the room, and adjustable color temperature make it the smartest lighting upgrade a working desk can get.
Buy this if your desk is a monitor plus a small work surface and you are tired of a lamp eating space or throwing glare across the screen. It frees up the whole desktop, lights your keyboard and papers evenly, and the wireless dial lets you tune brightness and warm-to-cool color without reaching. Ideal for anyone who reviews images, drawings, or color on-screen and also works with paper.
What we don't like
It is the most expensive pick here, and because it mounts on the monitor it lights the desk in front of the screen — it is not an arm you can aim at an easel across the room. Very thick or unusually curved monitors can need the fit checked before ordering.
