Electric Light Radiant Energy Control Systems

A disinfecting LED lighting system comprising:

• at least one light fixture disposed in or on a ceiling in an environment and configured to output a first light and a second light, wherein the first light and the second light are emitted from independent sources and operate independently;
• and wherein:
• the first light and the second light both emit a portion of a spectral range as a disinfecting energy within a disinfecting wavelength range of 380 to 420 nanometers.
• the first light emits a first output, wherein at least 20% of the spectral range is within the disinfecting wavelength range;
• and
• the second light emits a second output, wherein at least 70% of the spectral range is within the disinfecting wavelength range;
• and
• at least one sensor in communication with the at least one light fixture and configured to detect a characteristic of the environment;
• and
• a controller in communication with the at least one sensor and the at least one light fixture and configured to cause an event;
• wherein the event comprises an adjustment of the first light and/or an adjustment of the second light.
