Details
Light for your keyboard, notebook, and everyday work, without a lamp base on the desk. The 42cm aluminum bar sits above a compatible monitor and directs light toward the space in front of you.
Use the touch controls to adjust the light, then check the angle from your usual seat. Reflections depend on your screen finish, placement, and room lighting. Keep some background light in the room for a balanced setup.

Fit & compatibility
Measure your monitor’s usable top edge and leave room for a webcam and the USB connector. Check the display’s thickness, bezel, and rear shape: the mount must sit securely without pressing on the active screen or covering vents. Screen diagonal alone does not establish fit. Compatibility with curved displays and laptop screens is not specified.
What’s in the box
One 42cm monitor light. Plan for a compatible USB cable and power source; a cable, wall adapter, and remote are not listed as included. Monitors and other desk accessories in the photos are for styling.
Care
Disconnect USB power before cleaning. Gently wipe the aluminum body and light window with a soft, dry cloth. Keep liquid away from the light and connector; avoid sprays and abrasive cleaners. Support the bar when adjusting it, leave slack in the cable, and never force the mount against your display.

What does an asymmetric light path do?
It directs light toward the desk in front of the monitor, with the aim of reducing light falling on the screen. Position, monitor finish, and room lighting affect reflections; it does not guarantee a glare-free screen.
Should I choose 42cm or 50cm?
The 42cm light is $59; the 50cm light is $64. Start with the usable width across the top of your monitor. Choose a length that leaves clearance for your setup. A longer body does not establish higher brightness or a wider measured light footprint.
Will it fit every monitor?
Fit depends on the bezel, display thickness, and rear shape. Check that the mount can sit securely without touching the active screen or covering vents. A supported thickness range is not specified; screen diagonal alone does not confirm fit.
Are a cable, adapter, or remote included?
One light is listed in the box. Plan for a compatible USB cable and power source; a cable, wall adapter, and remote are not listed as included.
