Digital Light Meter (Footcandles) reflective-and-greenhouse-films Designed for maximum efficiency andThis product is a precision instrument used to measure luminance (footcandles). The meter is fully cosine corrected for the angular incidence of light, meaning that if you are not holding the sensor perfectly perpendicular to the light source, the sensor will still read the light correctly. The sensor is stable and made of a long life silicon photo diode. The digital light meter accurately measures to 40,000 FC. The meters built in low battery
