Overview:
The digital lux meter LX1010B can measure up to 50,000 lux
It's used for checking the level of luminance, luminance is a measure of the amount of light falling on a surface. It is defined as the density of the luminous flux incident on a surface. It is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated. This convenient gadget is widely used in many areas such as construction, inspection, photography etc.
