A Surface Luminance Test is used to measure the intensity of light emitted from each of our light panels. Measured in LUX (with one LUX being equal to one lumen per square metre) the test indicates the amount of visible light on the surface of the panel.
Nine readings are taken across the surface of a panel, the average of these readings being the average luminance of the panel. It is important to note that the figures for the centre of the light panel are slightly higher, meaning that graphics are slightly brighter in the centre. The images and readings here are taken from an MDK Slimbright A2 light panel.
