Control systems for disinfecting light systems and methods of regulating disinfecting energy generated by disinfecting systems are disclosed. The control system may include a first sensor and a second sensor positioned within a space illuminated by the disinfecting light system. The first sensor may measure an amount of disinfecting energy provided to the space by the disinfecting light system, and the second sensor may detect an environmental characteristic of the space. Additionally, the control system may include a controller operably coupled to the first and second sensor. The controller may regulate the disinfecting energy generated by the disinfecting light system by adjusting the amount of disinfecting energy provided to the space by the disinfecting light system in response to the amount of disinfecting energy provided to the space by the disinfecting light system measured by the first sensor, and/or the environmental characteristic detected by the second sensor.
