Check that the ColorBox is properly connected to your chosen USB-C power source. Ensure the included USB-C cable is securely plugged into both the ColorBox and the power source, and that it is not dirty, wet, torn, or damaged in any way. If you’re using batteries, see if they are securely in place inside the ColorBox’s battery compartment. The ColorBox may not light up as brightly as it’s supposed to if the AA batteries are loose. Alternatively, try using the remote to increase the light box’s brightness setting. It’s possible that it may just be on its lowest setting. Do not use the ColorBox in wet environments, as these can interfere with its operation. If you have any questions, please don’t hesitate to contact our Customer Support team.
