Electromagnetic radiation of which a human observer is aware through the visual sensactions that arise from the stimulation of the retina of the eye. This portion of the spectrum includes wavelength from about 380 to 770nm. Thus, to speak of ultraviolet light is incorrect because the human observer cannot see radiant energy in the ultraviolet region. Adjective meaning high reflectance, transmittance or level of illumination as contrasted to dark, or low level of intensity.

Light source: An object that emits light or radiant energy to which the human eye is sensitive. The emission of a light source can be described by the relative amount of energy emitted at each wavelength in the visible spectrum, thus defining the source as an illuminate. The emission also may be described in terms of its correlated color temperature.
