WebEncircled flux is being adopted as a purportedly more precise method of defining mode fill for bandwidth simulation and loss testing. Encircled flux (EF), defines the integral of power output of the fiber over the radius of the fiber. It sets limits for the amount of optical power included within a specified radius of the fiber core. WebA source radiating a power of one watt of light in the color for which the eye is most efficient (a wavelength of 555 nm, in the green region of the optical spectrum) has luminous flux of 683 lumens. So a lumen represents at least 1/683 watts of visible light power, depending on the spectral distribution. Lighting [ edit]
