📏 ANNMETER AN-881D Digital Illuminance Meter, Lux Meter with 0.01-400,000 Lux (0.01-40,000 FC) Foot Candle Measuring Ranges, Light Meter for Plants, Par Meter with 270° Rotatable Sensor Review

Seems to work well enough to test light at sensor point. The device itself feels incredibly cheap, like a dollar toy. The battery compartment is secured with a screw, creating a totally unnecessary barrier to accessing the batteries when they need to be replaced. Now if you want to use it anywhere in the field, you'll need to make sure you have a small screwdriver handy in case you need to change batteries.

This is not a perfect tester for detecting light coming from a flashlight in a room, but it is good for detecting light bulbs in a room. I don't like that every time I turn it on it shows the temperature in Celsius. In general, it's easy to read the panel's description and apply the settings. I like that it takes standard AAA batteries which are easy to replace. This meter feels good in the hand and the protective film and light sensor housing should protect it from damage.

I was planning on using this light meter to adjust the lighting on the plants to ensure I was getting the maximum exposure without burning them. My LED and the recommended readings I was expecting are not even registering on the device. For example, my light should be able to produce at least 20-100,000 (nominal) and this counter shows no more than 2000-3000. The instructions aren't very comprehensive, so I don't know exactly how to set up the meter. I had this meter reading below what I needed
