Abstract

A lighting device configured to deactivate dangerous pathogens (e.g., MRSA bacteria) in an environment. The lighting device includes at least one lighting element configured to provide light. At least a first component of the light comprising light having a wavelength of between 400 nm and 420 nm, and at least a second component of the light comprising light having a wavelength of greater than 420 nm. The first component of light has a minimum integrated irradiance of 0.05 mW/cmmeasured from any unshielded point in the environment that is 1.5 m from any point on any external-most luminous surface of the lighting device.
