LED Light Tracer Board, Eye Friendly Light Box with USB-C Cable & 2 Magnets (A4/A3)

EYE FRIENDLY: The design features flicker-free, evenly distributed light without mesh grids due to its patented, long-lasting LED chips with a color temperature of ~5000k (daylight). The brightness levels are balanced to meet the needs of the average user and their eye health. Unlike cold, blue lights, our drawing board provides a softer, less irritating light source, reducing eye fatigue and soreness USB-C POWERED: The tracing light box is powered by a USB type-C port, and the cable is 1 meter (3.3 feet) long. A computer, power bank, or USB plug can easily power the Santek LED tracing pad. The USB type-C port is non-directional. Plugging it is quick and easy from either direction STEPLESS BRIGHTNESS ADJUSTMENT: One touch control for ON/OFF and brightness adjustment. You can adjust brightness by pressing and holding the sensor switch, gradually dimming or raising brightness based on your needs and the ambient environment. The Santek light box screen is protected by a protective film.
