1. A smart Far UV fixture comprising:
a housing;
a Far UV source adapted for emitting Far UV radiation directly into an occupiable space at variable intensities, supported in said housing;
a smart power supply supported in said housing;
at least one sensor supported in said housing;
said smart power supply adapted to receive data from said at least one sensor;
said smart power supply further adapted for using said data from at least one sensor in making at least one human-safe determination of said occupiable space;
said smart power supply is in communication with said Far UV source such that when said human-safe determination requires a change in said Far UV source intensity, the smart power supply is in communication with said Far UV source to make said change;
said smart power supply is in communication with an IoT interface circuit adapted for directly connecting with, and exchanging data with a remote sensor;
said smart power supply is in communication with an IoT interface circuit adapted for directly connecting with, and exchanging data with, and reporting to, using wireless technology with the occupants of said occupiable space, at least one human-safe determination relating to the Far UV exposure of occupants in said occupiable space;
a cutoff filter adapted for filtering selected wavelengths in said Far UV C spectrum;
said cutoff filter including a plane;
when light emitted from said Far UV source at an incident angle of 0 degrees to said plane, said cutoff filter is adapted to block wavelengths longer than 234 nm;
said cutoff filter allows substantial transmission between 234 nm and 237 nm;
said cutoff filter reduces radiation from 240 nm to 400 nm to less than 1% of peak 222 nm radiation.
