Designed and feels premium right out of the box, including the desktop remote. Easy to install and use. Controls are intuitive. Instantly made the computer desk feel cozy and the lighting made it so much easier on my eyes. I LOVE the auto on/off sensor. Basically the moment you sit down, it'll detect that you're there and turn on automatically. If you're gone for about 3-5 minutes, it shuts off on its own. I use the auto-dimming feature during the day to let it adjust on its own, then at night time I switch manually to the warm light setting. Only downside is that it looks quite bright from the side but why would you be staring at it from the side in the first place? Yea this one's expensive vs others but it's worth the price and you can keep it for a looooong time.

Thoroughly impressed with this device. I read through all of the reviews before buying, including negative, and can say my experience has been completely positive. I love the backlighting, though I wish it projected further down behind my monitor. The front lighting is great and can easily be positioned to light up my desktop, but minimal glare on the screen itself. The puck is brilliant. It's easy and intuitive to dial in brightness, color temperature and front/back lighting. I haven't experienced any of the touch issues on the controller that others have. It takes just a like tap to select a setting and it's easy to save a favorite setting via the <3 button via a long press. I've had no issue with it waking up when I sit down at my desk. Perhaps it's been more of a positioning issue for others? Mine lives just above my trackpad and I've yet to have it not turn on the light when I sit down at my workstation. It does fit nicely on my 27" Apple Studio Display. I like the clamp design because it sits up there lightly, balances well, but doesn't exert much force on the screen. The build quality appears to be excellent. The light housing and puck are made from aluminum. The puck is nicely weighted and it rotates very smoothly. Despite the cost, I feel this was a very worthwhile upgrade to my studio. Update 11/8/25: I mistakenly thought the sensor to turn the light on was in the puck. However, that wouldn’t have made sense. The sensor is in the arm underneath the light bar, facing the user. That said, it continues to work flawlessly and I’m still very pleased. My favorite feature has become the “favorite” button (go figure). I can adjust the lighting to whatever I’d like at the time, but can immediately revert to my preferred setting for editing photos.

Best quality! The light can fit with a video camera on it. It can automatically turn on and off with a motion sensor and a light sensor. I love the back light, and I also have the option to turn it on or off. The adjustment of light temperature is very intricate, and it can even be suitable for professional shooting. It's worth any penny. The weight is just the right weight. I am going to make more purchase from Benq!

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.

THE GOOD: Overall this is the best option out there right now for 2 sided light - well worth the $$. Mine sits on a 27" iMac and it matches overall aesthetic well and looks/feels premium. Front light is sufficient (I do both digital and hard copy paperwork at my home office) to light up everything on my desk. The fact that light doesn't reflect/glare off my screen is excellent. THE "MEHH": 1) could be 3-4" wider, especially if working on larger projects and have books/paperwork to the side of the monitor or keyboard... that said it's probably enough for most people. 2) Remote is a bit annoying because it's too easy to turn and skip the setting you're trying to adjust, there's literally 0 friction when turning the wheel. 3) lack of any sort of app control is somewhat annoying considering that it has wireless connectivity especially since remote programming (which is minimal as is) isn't that intuitive. 4) My main gripe and reason for 4 stars instead of 5... no independent color temp setting for front/rear light - both have to be set to simultaneously to the same temp - this is unfortunate because it doesn't accommodate the color/texture of the wall behind the monitor... clearly there's independent control of the luminosity between front and back LED's, so there's no technical limitation on why you shouldn't be able to set the color temp individually. Regardless - I recommend this light for any home office.

Great concept and execution, perfect lighting solution. I have it mounted on a BenQ MA320 for general use and photo editing. Eliminates glare, no screen obstruction, and frees up space on the desktop. Front & backlight independent brightness control is helpful and the included webcam mount pedestal is a nice touch. Quick & easy to install/setup. Fancy remote control puck works great but is probably overkill unless you are constantly adjusting, could have put simple buttons on unit itself to set & forget.
