Using this Camera-Mount LED Photography Light is easy. First, get a Sony NP-F550 battery and insert it into the light. Then, you can adjust the color temperature to either a warm 3200K or a cool 5600K using the color temperature knob. You can also control the brightness with the dimmer knob up to 11W. The pan tilt shoe mount base allows you to position the light as you need. To check the battery balance, just press the testing button. Remember, the camera battery is not included, so make sure you have an NP - F type battery. When not in use, store the light in a dry place. Keep it clean by gently wiping it with a soft cloth. Avoid exposing it to extreme temperatures or moisture.
