I had seen this product used on Sheffield Made Plants and wanted to give it a try, as I will be bringing my house plants indoors in the near future, for the winter season. As any plant lover, I want my plants to happy and thriving, and in the most ideal conditions I can provide. Therefore, ensuring they are getting the ideal amount of sunlight is essential. This device has allowed me to check different rooms and distances from the windows, to find the ideal space for my plants to spend the winter months. In addition, because I will be placing them on a wire rack, I will be purchasing Grow Lights to ensure I have the optimal lighting for my plants to thrive this winter. The device fit nicely in the palm of your hand and is quite easy to use, and the instructions are easy to follow. It requires 3 AAA batteries, which the manufacturer has generously provided, which adds to the value for the money. You have the option of Lux or Foot Candles for measuring the light. My only complaint is that it only report the temperature in Celsius and there is no option to report in Fahrenheit. But honestly, if thats the only issue, this little gadget is a steal for all it does and what you get. So, if you're in need of knowing how much natural or artificial light you're getting in a room, buy this. It is a great little device.

I have houseplants and noticed this year that some of them were weakend and "dying". After talking to someone about my houseplant issues, they mentioned a light meter that they use. He suggested my plants were not getting enough light even though it's very bright in my home. Some of were plants were about 15 feet away which I thought was still bright enough. I eventually researched more on how much light plants should receive when they are in your house. This light meter works great!All I did was install the batteries it came with and turned it on. It was already calibrated. I removed the cover and started measuring the light coming in from my windows. I measured the light in the middle of my room and there is a big difference! I would have never thought it was that big of a difference since my home gets southern exposure sunshine all day! So, yes, this light meter helps! Now, I will position specific plants in certain spots in my home using this intuitive and easy to use light meter!

Arrived with dead AAA batteries. Replaced batteries and tester came up and works just fine!

This is a great tool for telling you the lumen in a particular area. I have used this to check my CoolFire LED lights, which they exceeded their advertised brightness. I've also used this to see how much brightness is coming from a floor lamp in a room. While saying a room is bright or not bright is one thing, having the evidence to back it up is another. It's a quality but inexpensive meter that is great for basic everyday use when you need to know how bright an area or something is. It's handheld, which makes it easy to use.

If ur trying to change from °c to °f all u do is turn it off and while it's off hold the (hold) button (do not let it go) and turn it back on while holding down the hold button at the same time and it will be on °f n do the same thing to turn it back to °c but also when it goes back on the HOLD button will be on so make sure u hit the hold button again to turn off hold so u can use it again. If it's not working for u look in the top left corner of the screen n make sure it doesn't say hold of it does just turn off the hold button. But I love it and I highly recommend it and I would def buy it again if I needed another for any reason. It works great great quality and size. Highly recommend

Currently using it for house plants and seeing where to place house plants in my home. Very useful for figuring out how far from the plant a grow light should be.Controls are super easy and intuitive, had it figured out in minutes out of the package.
