1. A light emitting device comprising:
a substrate; and
one or more light emitters disposed on the substrate and configured to emit a light to inactivate microorganisms on a solid surface a distance away from the substrate wherein the substrate is a circuit board comprising an on-board controller;
wherein to emit the light, the one or more light emitters are further configured to produce a radiometric power that satisfies a threshold, wherein the threshold is based on a target irradiance at the solid surface sufficient to initiate inactivation of the microorganisms on the solid surface, wherein the target irradiance is approximately 1 milliwatt per square centimeter (mW/cm2) across at least a portion of the solid surface;
wherein the radiometric power is based on:
a number of the one or more light emitters,
beam angles of the one or more light emitters, and
the distance; and
wherein the light emitted by the one or more light emitters comprises:
a proportion of a spectral energy of the light, measured in a 380 nanometers (nm) to 420 nm wavelength range, of at least 50%; and
a full width half max (FWHM) emission spectrum of less than 20 nm and centered at a wavelength of approximately 405 nm to concentrate the spectral energy of the light and minimize energy associated with wavelengths that bleed into an ultraviolet wavelength range.
