Luminous intensity. In photometry, luminous intensity is a measure of the wavelength -weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.
Glare (vision) Glare from a camera flash during a Sumo fight. Glare is difficulty of seeing in the presence of bright light such as direct or reflected sunlight or artificial light such as car headlamps at night.

A dazzler is a non- lethal weapon which uses intense directed radiation to temporarily disorient its target with flash blindness. They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for hailing and warning. [1] Targets can include electronic sensors as well as human vision.

Therefore, he did not have physical representations that other traditional ancient Egyptian gods had, instead represented via the sun disc and reaching rays of light tipped with human-like hands.
