Review on Ultimate Lux Light Meter: Revolutionizing Photography & Plant Growth with LED Photometer & Digital Illuminance Sensor by Christina Potter

Took it out of the box and put in a new set of batteries and started testing my lights. I have a photographer's light meter, but I bought it for the greenhouse. This meter showed completely different results for the same type of light source compared to my other meter. Then I decided to check the temperature sensor. Not even close. The smart home thermostat read 72 degrees and let this gauge adjust for 30 minutes but still read 82 degrees. I then took it to my basement bathroom where the temperature is 65-68 degrees and left it there for 30 minutes to adjust and it read 81 degrees. I'm sending it back and trying another brand.
