I often need to Skype to people in different time zones, which can mean doing so in limited light conditions with only my computer screen as a source of light. This webcam still picks up pretty good colour and clarity and the room looks better lit in the image than it actually is. I only use HD rather than the webcam's ultra HD capability, but that is more than good enough to hold documents and the like in front of the webcam so they can be read by another party on the other side of the world. It is expensive and there are cheaper alternatives that will probably do a similar job for most people in ordinary and well-lit conditions. But if you have particular needs for a clear and reasonably well-lit video image where it doesn't really exist, I'd recommend this webcam as a good compromise.
