I forget the full measurements for UV-C. I want to say UV-C is between 280 nm and 200 nm. After investigating, it looks like Far C is 222 nm with filters set for safety purposes at 233 nm.

Columbia University is the originators of the Far UV C concept and studies. Here's some starting research points.

And they have their technology licensed to USHIO.
