Plant Light Intensity Meter 

The Plant Light Intensity Meter is designed specifically for gardening applications. It measures the intensity of natural sunlight, fluorescent tubes or HID lights in footcandle increments. 

It has a remote Universal-Sensor-Probe (with a 2-1/2' cord) that is capable of reading light at any angle or in any location.

You can use this light meter to determine which areas have the best light coverage allowing you to properly rotate plants to receive the best amount of light. Or use it to gauge your lamp's output to help determine when its time to replace a worn out lamp.

Includes a comprehensive guide that details light requirements of over 400 species, along with explanations on color spectrum, photosynthesis and photoperiodism. Learn the effects of light during seed germination and plant development.

The Plant Light Intensity Meter is permanently calibrated with a lifetime silicon photocell. Accurate to 2%.
