On the site "Care222modules use an excimer lamp in combination with a special optical band pass filter that blocks the ultraviolet wavelengths that could have a harmful effect on people. Care222 is the only Far UV-C product in the world with this key technology." why is this key technology so difficult? And why is the product so expensive?

Looking at uvb there use to be several afordable manufacturers with good test data but they all closed shop. What is left either doesnt work or is scarry expensive.

The lamps are cheap the coating is hard to develop. Im not sure but it seems if you want to produce it you have to redo the rnd to figure out how.
