Styled in silver, the BenQ ScreenBar Plus e-Reading LED Lamp is designed to help out with the eye irritation that often occurs when you spend hours in front of the computer screen. A built-in ambient light sensor illuminates to 1000 lux, automatically attenuating itself in response to the surrounding brightness to give you the right light. You can also adjust the color temperature and brightness manually as well as turn the light on and off. The ScreenBar has a specially designed clip that lets you easily and neatly secure it to the top of most monitors, and it will not cause glare off the computer screen.
