Review: Perfect desk lamp for busy desks. - This is the perfect desk lamp for those of us whose desks are too full of stuff to support a free-standing lamp. I have it clipped to a 27" Apple monitor, and it works perfectly. No noticeable impact on the screen, very good quality light, and it lights up my desk. It's very high quality, particularly the remote. I didn't think the backlight would be useful, but I actually like it. My one quibble is that it has only a single preset. I'd vastly prefer two—one for daytime settings and the other for (much yellower and dimmer) nighttime. The automatic adjustment dims the light a bit too much for my tastes. It's expensive, but worth every penny.
Review: where have you been all my life? :D how did i get by without a monitor light bar for so long?!?!? - not quite sure how i went so many years without a monitor light bar!?!?!? most of the times, we're looking at our screen, but you might have papers, mail, etc. that you have on your desk that you need to look at also. before, i had lamps next to both sides of my desk, but i realized that my desk was extremely dark and hard to see papers and other stuff that i needed to read. i started researching options to make my desk brighter and came across this. LIFE CHANGING! like the song goes... "i can see clearly now...", lol. seriously, i can't imagine doing any desk work without this light bar. i haven't tried others, but this one has been great! specific features that i love: + the back light and ability to adjust the front light and back light with the dial is great! + the motion detector senses when you're not at your desk and turns off automatically to save electricity/money/environment! although i give it 5 stars, there are couple minor things i wish were better: - i use an external logitech hd video camera, and i had to play around a bit to figure out where to place; finally settled on placing it on top of the thick arm part of the light bar (that connects to the thin light bar); i had to tape the video cam to the light bar arm so that it would not fall off; also the video cam picks up part of the light that the light bar emits, but only appears as a fine line in my video when on calls - i have a glass desk, so the light reflects a little off the desk; it was a little distracting at first, but don't notice it now; and usually when i look down at my desk, i likely have paper(s) that i need to look at, so it blocks the light reflection; i could also look into buying a matte anti-glare screen protector and cut it to the dimension of the reflection on my glass desk and affix to my desk. but again, not anywhere close to being a deal breaker. the benefits certainly outweigh the demerits by a lot! quality is well made and fits well (definitely not flimsy; secure on my monitor), and the matte dark grey color is great (a matte black version would also look great)! overall, extremely happy! :)

## Questions & Answers

**Q: Why does the light turn on and off by itself?**
A: You might have activated the auto on/off function, which detects motion in a 23.6±3.9" cone-shaped area ahead.

**Q: Why doesn't my wireless controller work?**
A: The controller is not faulty. When idle, the icons dim. To activate the controller, tap any function icon first (not the display panel). Then rotate the dial to adjust brightness/color temperature, or press another icon to use its function.

**Q: Why do I see glare on my screen when using ScreenBar Halo 2?**
A: ScreenBar Halo 2's asymmetrical optics prevent screen glare. If you notice glare, the lamp may not be mounted correctly. Please ensure the clamp’s top is completely flat, not tilted. You can also rotate the lamp to adjust the angle for your monitor.

**Q: Is my monitor compatible with the ScreenBar Halo 2?**
A: ScreenBar Halo 2 fits monitors 0.17–2.36" thick and 1000R-1800R curved, including Apple Studio Display and iMac. Ensure the clamp sits level on top of the monitor and the lamp does not tilt forward when mounted. For more details, please contact BenQ.

**Q: Why does the power on/off button on the wireless controller keep blinking and fail to control the lamp?**
A: The blinking means that the controller has lost its connection with the lamp. To restore the connection, please follow the tutorial video on this product page or the guide on BenQ’s website. For more help, contact our customer care via online chat.
