LUX vs PAR Meter | Can You Use a Lux Meter with Grow Lights?

In this video I show the difference between using a standard light meter and a quantum flux par meter. Can you use a lux meter to measure grow light intensity? YES and NO. Lux meters test mainly the green part of the visible spectrum and therefor will not give a consistent readout between various types of grow lights. PAR meters test the entire visible spectrum and can be used to test any type of light so long as you use the proper model and is a reliable brand.
