Review on Leaton Digital Luxmeter: Accurate Light Meter 🌞 with LCD Display (Range: 0.1~200,000 Lux Luxmeter, 0.01~20,000 Fc) by Rod Evans

I have no way of calibrating or testing this unit but it seems reasonably accurate. Compared to my phone's light meter, the numbers are relatively close (of the same order of magnitude, at least) and I would trust this device more than the phone's light meter. connected to the meter by a piece of rubber or the like, or the back cover has slipped off. Something that kept it with the device so you didn't have to wear/keep an eye on it when using the meter. Comparing the light levels in different environments is pretty amazing. Since humans see light more or less logarithmically, we hardly notice the same discrepancy in light intensity. A normal room might be 100 lux, a shade outside might be 25,000 lux. Definitely a good little light meter for the price. This is a little novelty, useful for checking if your plants are getting enough light to use as a light meter for photography and the like.
