Here is that light on it's "medium" setting the other night on my Fuji. It does the work. I paid $25 from a USA based shipper on Amazon. Can't beat the price. Battery life is great as well.
I don't care if it's not 5000 lumens - that's an insane claim anyway. All I'll say is it's plenty bright, plenty cheap, has a good enough mount, and the battery lasts a long time. What's not to like for the price? I could care less what name is on it.
