Light Reflectance measurement using lux meter

This is a simplified measurement technique that works best during overcast conditions. Try to hold the lux meter as far away as possible from your body to avoid self-shading from the person conducting the measurement. In this demonstration, we are measuring the light reflection of the driveway tiles. If you are measuring the light reflectance of a smaller surface, say, a tile that is only 1 x 1 meter, you should hold the lux meter closer to the surface, say, about 0.25 meters above the surface to be measured. Moreover, try to place the item to be measured on a surface with a similar light reflectance and/or colour.
