Not every meter (especially lower grade ones) will be consistent in their readout. It will vary between brands and models. In this video I give you a conversion factor to use this meter instead of an expensive PAR meter. Again...this only works for white light sources roughly between 2500K and 7000k. In order to calculate the conversion factor, I used my Apogee MQ500 Par meter which is lab tuned.
