A light delivery apparatus comprises a waveguide, a pump source and a fluorescent emitter. Pump light from the pump source is transmitted through the waveguide to the emitter. The emitter comprises a plurality of quantum dots. The pump light is absorbed by the quantum dots and re-emitted as light with a predetermined wavelength that is longer than the wavelength of the pump light. The predetermined wavelength of the emitted light is selected to match one or more activation wavelength(s) of a photoactivated chemical.
