A lighting system, comprising: an array of ultraviolet radiation sources configured to irradiate a surface of a light sensitive surface object with ultraviolet radiation having a wavelength range that includes ultraviolet-A radiation and ultraviolet-B radiation, wherein each of the ultraviolet radiation sources is configured to operate in a predetermined wavelength range that includes at least one of: a UV-A radiation wavelength range or a UV-B radiation wavelength range, wherein at least one of the ultraviolet radiation sources is configured to operate at a peak wavelength that is within the UV-B wavelength range; a plurality of light sensors configured to measure light intensity at the surface of the light sensitive surface object, wherein each light sensor is configured to measure light intensity in a wavelength range that corresponds to the predetermined wavelength range emitted from at least one of the ultraviolet radiation sources in the array; and a controller configured to control the light intensity over the surface of the light sensitive surface object by adjusting operational power of the ultraviolet radiation sources as a function of light intensity measurements obtained by the light sensors, wherein the controller is configured to: use the light intensity measurements to determine whether each ultraviolet radiation source is illuminating the surface of the light sensitive surface object at a dose that delivers the ultraviolet radiation at an intensity that is within a predetermined acceptable variation with a maximum intensity value targeted for the surface,; and adjust the power of each ultraviolet radiation source in response to determining that the ultraviolet radiation source is illuminating the surface with an intensity that has an unacceptable variation with the maximum intensity value targeted for the surface, wherein each ultraviolet radiation source that is adjusted in power is configured to deliver an adjusted dose of the ultraviolet radiation that is a function of an amount of the unacceptable variation with the predetermined light intensity value, characterised in that the controller is configured to increase an uniformity of a distribution of the light intensity over the surface of the light sensitive surface object by controlling some of the ultraviolet radiation sources to operate with more power and others to operate at less power. an array of ultraviolet radiation sources configured to irradiate a surface of a light sensitive surface object with ultraviolet radiation having a wavelength range that includes ultraviolet-A radiation and ultraviolet-B radiation, wherein each of the ultraviolet radiation sources is configured to operate in a predetermined wavelength range that includes at least one of: a UV-A radiation wavelength range or a UV-B radiation wavelength range, wherein at least one of the ultraviolet radiation sources is configured to operate at a peak wavelength that is within the UV-B wavelength range;
