Abstract: A system using a Far-UV light source is disclosed for sanitizing an environment. The light source can be automatically activated based on environment dimension information, environment usage information, light source specification information, and/or regulatory compliance information. Activation of the light source can be further based on sensor data from the environment, such as occupancy sensor data. The controller can further monitor and log light source usage, such as to update an expected remaining lifespan of the light source and generate a compliance report of light source usage. Activation of the light source can be further based on the expected remaining lifespan of the light source. When the expected remaining lifespan of the light source drops below a threshold, a maintenance prediction alert can be generated to facilitate maintaining and/or replacing the light source.
