Lux Meter (Light meter)

Lux meters, sometimes called light meters, measure the intensity of illumination as distinguished by the human eye. This value does not correlate to an objective value of energy radiated or reflected, as different wavelengths within the visible spectrum are perceived with varying sensitivity by the eye, and lux meters evaluate light intensity in consideration of this variable. 

Hand-held digital meter comes in its own zip-up bag 16 x 16 cm
