Light Meter Digital Illuminance Meter Handheld Ambient Temperature Measurer, Range up to 200,000 Lux, Luxmeter with 4 Digit Color LCD Screen

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

Works really well. Game changer

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!

Works as intended for measuring how strong a light source is (Lux/FC(Foot-Candle)). You /can/ use this for plants, but you need to be looking up Lux or FC on Google and that's pointless. This is NOT a PPFD or PAR meter which is the measurement you want if you're concerned about your plant's health. You may get positive results, but this is not for plants. Use the app Photone if you're trying to help the plants or get a PPFD meter.

I have to be very honest... I was gonna buy this to use it once to measure my grow lights and then return it... but I liked it so much that I ended up keeping it. Would definitely recommend

One of the standout features is its user-friendly interface. The buttons are well-placed, and the LCD screen is bright and easy to read even in low-light environments. Switching between modes is seamless, allowing me to work efficiently on set.

Seems nice but while going through manual seen something that should be in description that it is designed for incandescent lights

I am in no position to tell you if this is accurate. I don't have a reference machine to check calibration. It does seem to give readings that make sense to me. Certainly easy to use. It can certainly answer the question "which is brighter?" Not sure if the values are really accurate. I have no way to tell.
