Review on INFURIDER Illuminance Rotatable Photography Measurement by Tres Carmon

I bought this for evaluating solar panels as a replacement for a solar energy meter (pyranometer) at a much cheaper price. It did everything I expected of it and allowed me to distinguish bright sunlight from sunlight of almost the same brightness. I can compare the reading to the standard AM value of 1.5 lux (109,870) and calculate the power at AM 1.5. I don't have the equipment to calibrate it, but it seems fairly accurate as my max readings so far are 104,800 lux. The smog from the wildfires reduced sunlight, and this meter showed how much sunlight was being absorbed. It comes with a nice protective case and a screwdriver to open the battery compartment,
