<Luminous intensity> is <luminous flux> per outgoing <solid angle>, measured in <candelas>. It is the visually weighted counterpart of <radiant intensity>. The same total <luminous flux> concentrated into a narrower cone can give a greater <luminous intensity> within that cone.<OSA Handbook of Optics, Volume III Visual Optics and Vision/Radiometry and Photometry: Review for Vision Optics>{ref}
