- Reviewed in the United States on December 11, 2024Works like a charm! I love working in the dark with ambient lighting. This helps with eye strain and honestly anything else. I use it for when I am crafting or doing my nails on my desk as well. The functions are straight forward and the best part is that it looks great!
- Reviewed in the United States on June 4, 2024I also own the Halo version of this light that I use in my office, which is pretty fantastic, but this one is even better if you don't need the backlight from the Halo, and don't care about having the wireless remote control. Like the other BenQ ScreenBar lights, the light output is extremely well controlled and of fantastic optical quality if you care about things like color accuracy and brightness and not casting light onto your monitor illuminating any spec of dust that might be on it.
This one is both brighter, as well as provides slightly improved color rendering even compared to the already fantastic ScreenBar Halo and other previous generation products. The motion detection feature is also a really nice addition, which partly makes up for not having the remote control puck since you only have to set it to what you want to use it at and then enable the motion detection mode and forget it. The implementation is even thoughtful enough that you can either walk away and let it turn itself off after 5 minutes, or tap the power icon to turn it off immediately, in which case it temporarily disables the motion detection for 30 seconds so you can step away from your computer before it re-enables the sensor again to turn back on automatically when you return. Little things like this don't seem like a big deal, but they just make using the product that much simpler and more pleasant than not having it, and over the long haul, that kind of little thing really adds up.
This one makes it clear, like the previous models, why BenQ currently seems to lead the market with these monitor mounted desk lights. I wouldn't use anything else, and I'll never be without one again - it's just that much of an improvement over all the alternatives I've tried, from desk lamps and table lamps, to floor lamps, improved room lights, and competing monitor lights. BenQ monitor lights have their high ratings for a good reason.
EDIT: I see one review mentioned the power button not being illuminated when the light is off. This is true, but to work around this to some extent, the power button is on the right side of the control panel in the middle of the light, and it's touch sensitive. This means you can just touch the right half of the light and slide your finger left towards the center and when you reach the power button, the light will turn on without you needing to know exactly where the button is. This may help other owners who have the same issue but otherwise like the quality of the light.
- Reviewed in the United States on January 25, 2025It works well and I recommend it. The instructions are a bit brief and pictorial.
- Reviewed in the United States on July 3, 2024I'm so glad to have found this light! I like that it is up out of the way without cluttering my desk. It casts a very even pool of light on my desk, and even to the sides a bit, without highlighting the surface of my ultra-wide curved monitor. The automatic on/off works well sensing my presence, and not turning on if I simply walk into my office. I have to pretty much sit down at my desk to have it turn on.
I wasn't immediately aware you can adjust the angle of the light bar housing. When I first installed it on my monitor it was glaring into my eyes just slightly. I later discovered the light bar easily adjusts just by rotating the aluminum shade with my fingers.
I like the adjustable color temperature. Automatic brightness mode, though, limits you to a middle-of-the-road white temperature. I prefer cool light in the mornings and warmer colors in the evening, so I have set the Favorite button to warmest/dimmest. That's my "done with my workday" button.
I knocked a star because of the limitation of auto-brightness having a non-adjustable color temperature. As well, this really should adjust color temperature automatically, either by schedule or a ambient color temperature sensor.
There is no detectible flicker, either, even when waving something quickly in the light. That's a major plus. CRI is also very good with accurate colors. I was surprised how good the bowl of fresh berries I bright into my office looked.
- Reviewed in the United States on February 20, 2025This has been a great addition to my desktop setup. Easy on my eyes and does the job well.
- Reviewed in the United States on December 13, 2024This is wonderful addition to my Apple Studio Display. It fits nicely on top, it looks great, and it lights the area underneath the display perfectly without reflecting on the screen (unlike every desk lamp I had tried to use before). Highly recommended.
- Reviewed in the United States on January 5, 2025Good light with reasonable coverage, but causes my 32 inch monitor (Dell U3223QE) to constantly flickr (likely due to the light exerting pressure on LCD panel) after a few weeks of usage.
- Reviewed in the United States on April 8, 2025Good item

5.0 out of 5 stars Cher mais bien meilleur que la compétition
Rien à voir avec la qualité médiocre de la compétition:
- bonne stabilité et adaptabilité
- détection de mouvement: s'éteint quand on ne l'utilise pas, énorme plus par rapport aux autres modèles
- ajustement automatique en fonction de la lumière ambiante
- retient les réglages avec possibilité de sauvegarder un favori
- éclaire parfaitement le bureau sans illuminer l'écran: l'angle est réglable
La perception de ce qui est cher varie selon les points de vue; difficile à dire si ce produit vaut vraiment presque 3 fois le prix de la compétition. Cependant la qualité est amplement au rendez vous et après avoir renvoyé 2 autres articles similaires bien moins chers, c'est au final celui ci que je garderais.

5.0 out of 5 stars Sehr erhellend!
Preislich ist die Leuchte sehr weit oben angesiedelt, hinterlässt aber vom Ersteindruck ein Gefühl eines guten Gehenwerts. Das Verarbeitungsniveau ist sehr gut und alles wirkt gut durchdacht. Die Lichtleistung ist sehr ordentlich und die Lichtfarbe kann auch angepasst werden. Die Automatik läuft gut und passt die Farbe und Helligkeit auf die entsprechende Situation adäquat an. Sollte man händisch etwas einstellen wollen, reagieren die Sensortasten feinfühlig und durch das Eigengewicht der Leuchte wackelt dann auch nichts. Der Abstrahlwinkel ist zudem in einem geringen Maß einstellbar und damit kann eine Spiegelung im Monitor verhindert werden.
Ein sehr schönes, funktionales aber leider auch teures Produkt.

5.0 out of 5 stars Brilliant bit of kit!
The light bar fits my Asus 27 inch monitor perfectly and has allowed me to stop using several other desk and floor lamps to try and get the right lighting for photo editing. The lamp has plenty of adjustment options inc intensity and colour temperature. It’s early days but I’m pleased with my purchase and yes it is one of the pricier options available. However when I consider what I’ve spent on camera kit, laptop and monitor, it’s a relatively small expenditure for a bit of kit that seems to perform really well.
