BenQ Screenbar Lamp

[MPN: ScreenBar Monitor Light] [IS SKU: LW_SCRNBAR]

BenQ's ergonomic, eye safe task lamp to light up your working or print viewing areas.

Ships free to most locations! See notes.


This is a nifty product from BenQ that takes up essentially no space, is USB powered, and provides ergonomic, eye safe light to your area, with automatic adjustment to recommended levels if you desire.

The light has a high colour rendering index (~ Ra 85) so is a good quality light for print assessment as well. Whilst designed to be mounted on screen (any monitor with a bezel width of 1-3cm, although we have one mounted on a 5cm deep Eizo bezel here so it can go wider if you have an older monitor), it can also be mounted above e.g. pinboard for a very inexpensive, high quality print viewing setup.

BenQ Say:

ScreenBar eReading Lamp

Simplify the complicated,
Eliminate the excess

Auto Dimming - Space Saving - No Screen Glare


Enhance work pleasure Relieve eye strain

When working all day, Don’t abuse your eyes!

Research shows that we work on the computer for an average of 5.7 hours each day. Staring at the screen for so long causes eye irritation. To eliminate this discomfort, enough rest helps, but the key to relieve eye strain is sufficient lighting.

Eye care: brightness is key

The American National Standard Practice for Office Lighting recommends illuminance level at 500 lux.

However there are problems with traditional lamps - Incorrect Brightness, Limited Space, Screen Reflection

Auto Dimming

no guessing, just knowing

The built-in ambient light sensor automatically illuminates to 500 lux

How bright is right? No need to guess anymore! ScreenBar e-Reading lamp is equipped with a sensor that promptly detects the surrounding brightness and then supplements it with just the right light.

* Under normal circumstances, auto dimming mode will illuminate to 500 lux. While in a dimly lit room (under 50lux), the lamp automatically adjusts illumination to 300lux, thereby eliminating the discomfort caused by a strong contrasts of light.

Space Saving

The patented clip design instantly attaches to any monitor

With BenQ’s unique design, there is no need for tape or screws that damage your computer.

Glare Free

no reflection, only precision lighting

The asymmetrical optical design ensures zero reflective glare off the screen

ScreenBar e-Reading lamp has an asymmetrical optical design that only illuminates the desk and doesn’t shine on the screen, avoiding reflective glare.

The whole working area is crystal clear

The 500 lux illuminance of the desk surface ensures that you see everything in front of the screen clearly. Illuminates 74 by 35cm.

Quality LED light source ensures proper eye care.

Non-flicker - Compliant with IEEE PAR1789 regulation of flicker in LED lighting

No blue-light hazard - IEC/TR 62778 assessment deemed it free of blue-light hazard

For comfort, the warm light lets you relax and replenishes your energy.

While working, the cool light allows you to concentrate and boosts efficiency.
