A method of inactivating one or more pathogens in an environment. The method includes providing light from at least one lighting element of a lighting device installed in the environment, the at least one lighting element configured to provide light toward a target area in the environment, the provided light having at least a pathogen-inactivating first component in a first range of wavelengths of 400 nanometers to 420 nanometers. The pathogen-inactivating first component of light produces an irradiance of at least 0.01 mW/cm.sup.2 as measured at a surface in the target area that is unshielded from the lighting device and located at a distance of 1.5 meters from an external-most luminous surface of the lighting device. Providing the light causes the one or more pathogens to be inactivated.

A method of providing doses of light sufficient to deactivate bacteria throughout a volumetric space. The method includes: (1) receiving data associated with a desired illuminance level for the space, indicative of an estimated occupancy of the volumetric space over a pre-determined period of time, and indicative of dimensions of the space; (2) determining, based on the received data, an arrangement of one or more lighting fixtures in the volumetric space, the one or more lighting fixtures configured to at least partially emit disinfecting light having a wavelength of between 400 nm and 420 nm, and a total radiometric power to be applied via the one or more lighting fixtures to produce a desired power density at any exposed surface within the volumetric space during the period of time; and (3) installing the determined arrangement of one or more lighting fixtures in the volumetric space.

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.
