I'm really shocked that a light meter this inexpensive works at all, but it actually works really, really well. Compared against a professional lab grade system, this goes far beyond what I'd expect.
I'm tasked with testing a lot of different things, such as flashlights and home lighting solutions and now I can more accurately determine brightness and color temp. Excellent buy and very accurate.

Good light meter for measuring light for plants, buildings. etc. I will keep this in my tool kit when measuring light for other uses. I've owned a few of the old fashioned ones in the past, and this one is far easier to use. The values it gives are accurate, and it was easy to use. I also appreciate the case it came with.

The quality of this handheld light meter is good. It is made of a hard plastic. It feels really solid when its your hand. Come with a sensor cap, and case even has a little mini screw driver to open the battery door. I used this to measure the lux to get the correct spacing for my de gavitas at 5 by 5 the coverage was almost the same as when i had it in a 4 by 4. Overall very handy tool for measuring lux.

✔️ Verified Buyer

Ever wonder if the lumes on that new flashlight are accurate? This handy little device will tell you the truth.
Want to get the correct exposure or aperture setting.. this will help you know the right setting to use.
Small and compact. Easy to use and reasonable accurate for the price.

✔️ Verified Buyer

This unit makes it easy to determine whether an LED source provides the same approximate brightness as an incandescent source, ignoring the differential that is introduced by the fact that the two sources likely have different color temperatures. Even low light is easily detected: in a dark room, the unit properly registered the intensity of a dimly lit keyboard. The display has a backlight that can be turned on and off. The light sensor can be swiveled so that it can point where you want it while reading the display.
Overall, high marks for a useful meter. Build quality and materials, are consistent with the price point.

I use this meter to find Exposure value for my manual cameral. I have to do a couple of conversions from Fc to EV, then look at table to find aperture and shutter speed. All turns out great. The meter has LCD back light, so in dark environment you can use it to help read.
