Review on Enhance your Video Quality with YONGNUO YN300 III LED Light - Adjust Brightness & Color Temperature for Canon, Nikon, Pentax, Olympus, Samsung by Melisa Byers

I bought this product for an interview shoot but I noticed that during a longer recording the unit suddenly dimmed to 50% for a few minutes and then back to 100%. This ruined my recordings because the lighting suddenly changes during an important line of dialogue and the recording becomes unusable. I have contacted YONGNUO about this, but THEY HAVE NOT ANSWERED ME. I am willing to change this rating if you contact me and help rectify the situation, but for now I DO NOT RECOMMEND THIS LIGHT and DO NOT RECOMMEND YONGNUO PRODUCTS due to their lack of customer service. *I've attached a video to demonstrate mild choking. It's possible that this particular device has a manufacturing defect, but I can't be sure as Yongnuo hasn't responded to my attempts to contact her.
