How to use: First, connect the power supply to the video panel light and plug it into a power outlet. You can then adjust the bi - color and RGB settings according to your video - making needs. Notice: Since the mounting arm is missing, you need to find a proper way to fix the light in place. Also, as there are no batteries included, make sure you have a stable power source. Maintenance: Keep the light clean and dry. If there are any problems with the outer frame, you can try to repair it gently to avoid further damage.
