I also…to my own utter horror…need some kind of fill-in light for doing video. Because I’m normally back-lit in my office. And now I’m looking at all sorts of “beauty vlogger” products. 
@ross search YouTube for Peter McKinnon, he recently did a video where he bought low price stuff of Amazon to see how they worked. I’m pretty sure one of them was a fill light with diffuser. I’ll see if I can find it later.
