Light Intensity LUX Meters

Illuminance is measured by Luxmeters on the lux scale. Luminous intensity is measured in lumens per square meter (Lux or lx) or lumens per square foot (foot-candles or ft-c).  A Klux is a 1000 lux and about 1.1 Klux is the minimum light requirements for any plants for at least 12 hours per day to gain any benefit from fertilization. Above 10 Klux is preferred however too much direct light or change in light intensity can result in leaves bleach, scald and often plants will die.

Our meters will measure light intensity to help you monitor and control the amount of light your plants get for ideal photosynthesis to take place.
