FAQ
Is a monitor light bar better than a desk lamp?
For a computer desk, often yes. A light bar sits on top of the monitor and lights the desk at an angle that avoids glare on the screen, and it takes no desk space. A desk lamp is better if you also read paper documents or need light in a wider area.
What color temperature is best for working?
Cooler, whiter light (around 5000 to 6500K) helps with focus during the day; warmer light (2700 to 3000K) is more relaxing in the evening. Lamps with adjustable color temperature let you change through the day.
Does a light bar fit a curved monitor?
Some do. The BenQ ScreenBar Halo 2 lists support for curved monitors from 1000R to 1800R. Check the clamp range and curvature in the listing before you buy.
Can better lighting reduce eye strain?
Good lighting reduces the contrast between a bright screen and a dark room, which many people find more comfortable over long sessions. Also take regular breaks and set your screen brightness to match the room.
