Abstract
A lighting device includes a light source emitting light having a first bandwidth. A single optic device is coupled to the light source. The single optic device filters light having a preselected subrange of wavelengths within the first bandwidth to generate a first filtered light. The single optic device controls a shape of a beam of the filtered light. The filtered light creates a high-intensity narrow-spectrum light output. A second light source emits a high-intensity narrow-spectrum light output.
