Abstract: A disinfecting system for a lavatory may comprise an ultraviolet light source, a controller in operable communication with the ultraviolet light source, and a lavatory sensor operably coupled to the controller. The controller may be configured to track a number of consecutive incomplete dosage cycles. The controller may be configured to determine whether to implement a first dosage cycle or second dosage cycle based on a comparison of the number of consecutive incomplete dosage cycles to a threshold number.

Abstract: A method of verifying sanitization of an area may comprise: emitting, via a sanitization system, a UV-C light towards a desired surface to be sanitized, the UV-C light including a first wavelength between 200 nm and 280 nm; and determining the desired surface is being sanitized by verifying whether the desired surface absorbs the UV-C light and re-emits a visible light.

Abstract: A lighting unit may include a first light-emitting diode (“LED”), a second LED, and a third LED. The first LED may be configured to emit first electromagnetic radiation having a first wavelength of between about 600 nanometers (“nm”) and about 740 nm, the second LED may be configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm, and the third LED may be configured to emit third electromagnetic radiation having a third wavelength between about 315 nm and about 430 nm. Thus, the third electromagnetic radiation may be disinfecting UV-A radiation that is incorporated into a lighting unit that produces visible light.
