45°angle light can reduce screen reflection and glare while lighting up your keyboard and desk.
It's about four meters at the most.
We will complete the code matching at the time of delivery, if it doesn't work after the battery is installed, the customer may need to re-code it.
Sure, our asymmetric optics obtained the United States Utility Patent, the light only to the work area without reflecting people's eyes, and the full spectrum light is bright enough without flicking and glare, which can relieve eye strain.
We are looking forward to working with you!
