Ee is a measure of irradiance (power/unit area) within a 0.444" (1.128cm) diameter area, centered on the mechanical axis of the device and spaced 2.54" (6.45cm) from the lens side of the tab. This is geometrically equivalent to a 10° cone. Clairex reserves the right to make changes at any time to improve design and to provide the best possible product. Clairex Technologies, Inc.
