NEEWER 660LED Lighting You can adjust the white and yellow light. Adjust with the knobs to shoot like sunlight indoors, allowing for shooting tailored to your preferences. The illuminance can also be adjusted, making it useful for shooting with reduced light. Battery operation is possible if you prepare a separate dedicated battery. It's easy to use, and its functionality as a shooting light is excellent. The main body is relatively clean, but as shown in photos 8 and 9, the plastic part just below the screws for adjusting the left and right angles is cracked. *Angle adjustment can be fixed without any problems. It can be used, but since some parts are damaged, please consider it as a "junk item." The damage is to the plastic part that holds the LED panel's protective acrylic plate and prevents it from shifting left and right. I didn't have any issues since I don't take the plate in and out.
