I have one that sits on the floor. It is slimline LED lamp that has a floor base. It is similar to this one:
Slimline LED floor lamp. It was a present so I don't know where they got it or how much it costs. It gives me good coverage and since it is so slim, it doesn't block any controls on my machine. I like that it sits on the floor and I can bend it like crazy. I have used it for other things (like making videos on my phone) and it works great.
I hope you find what you need.
