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 432,000 Lux. The meter’s built-in low battery indicator means you’ll never be caught by surprise by a low-power product. It measures grow lights or sunlight and has three scales for precise readings.

The Active Eye Digital Light Meter is a convenient hand-held remote sensor and comes with cell battery (Lithium 3V CR2032).
