WebThe more I read about this, the more confused I become. Illuminance, as I understand it, measured in lux, is the perceived brightness of light on a surface. It's what you'd measure with an incident light sensor. Luminance, then, is how much reflected light you'd perceive looking at that surface. This is what the light meter in a camera measures. WebBrightness, which is also referred to as brilliance, is an expression of the relative intensity of the energy output of a visible light source. It can be expressed as a total energy value, which is different for each of the curves in the Figure 2. Another way to express brightness is the amplitude of the wavelength where the intensity is greatest.
