Luster Leaf 1875 Rapitest Suncalc Sunlight Calculator

I always have the hardest time figuring out if different parts of my yard are good for certain plants sun-wise. This Sun Calc is great. I've tried it in multiple parts of my yard and it reads accurately. One thing I noticed other reviewers saying is it did not give an accurate read and I want to give my suggestions for troubleshooting. First, this needs 12 full hours of LIGHT to read accurately. So it has to be put out at sunrise and picked up 12 hours later. If you put it out later and the full 12 hours run into evening darkness then that will throw off the reading. If it is a very cloudy day, that will throw off the reading. So do it on a day that is average for your area and make sure the sun calc is there for a full 12 hours of daylight. If none of that works, then you may have a faulty product. If you get a good product then this is AMAZING.

We are having a record breaking winter (it’s June. We have yet to break 75° and it rains all. The. Time. But the few days that we did have some sunshine, this sucker was so helpful. I thought my side yard was shady, turns out it’s mostly sunny!

Updating Review - I took this out to use it this year and it did not work. I opened it up to change the batteries and the ones that came with it leaked and eroded the thin terminal metal so this no longer works. I thought it would be okay to store indoors but I guess the batteries need to be removed when not in use. This was a complete waste of money.Updating review - The company responded to me with the sun ranges for each category. Posting here if you are interested.Full Sun – 6 + hoursPartial Sun – 4-6 hoursPartial Shade – 1.5 – 4 hoursFull Shade – Less than 1.5 hoursI placed this in an area that I expected to be partial sun and that is what the meter showed. It is easy to assemble, turn on, and use. It is also easy to tell when it is still measuring sunlight.It would be nice it the calculated level lit up as a solid light instead of a flashing light. With how quick it flashed I had to cover the two closest bulbs to make sure I was seeing the correct one light up.They also have poor product support. I reached out to see how they calculate the sunlight levels for each category. Depending on where you look, you can get different hour levels for the different categories of sun. Some also measure morning, mid-day, and evening sun differently. The company never responded to me.

Have a lot of areas that receive various amounts of light throughout the day - shade to dappled shade to full sun. Worked as indicated per instructions. Gave me reading after 12 hours on a sunny day. I did a hourly reading throughout the day and SunCalc's result matched what I anticipated, but nice to have it confirmed.

I purchased this as a used item from Amazon warehouse and it came to me in pieces and did not work. I am unable to move the review on its functionality.

Used it in multiple places around the yard.

Got this for my wife for christmas - she used it ONE time in the garden, and it didn't work after that. After taking the cover off to troubleshoot, we found that the batteries had leaked after less than 6 months and one use. The only reason I can think that may have happened was that water got in and corrupted the batteries.

This is very handy! So many times I’ve wanted different plants but I’m not sure if it would get too much or not enough sun. This is easy to use and tells you how much your select location gets. I’ve used it in several locations in my hard so I know what plants to get. I highly recommend

it only works if that day there isn't a single cloud in the sky. Does it ever happen in UK?

Look, you don't want to spend $200-$500 on a accurate readout on solar hours. You want to spend a nice, reasonable amount to tell you approximately how many hours of sunlight a certain area of your garden gets. Of course, it ONLY works on days where the sun is out all day ... so check the Forecast before using. I've used this originally to determine where to install my pool solar heater ... and I'll use it for gardening later. This thing is easy to use - like, totally braindead.

First day I tried didn’t work. After 12 hours was not showing any information. Second day I left it for 14 hours and it worked. It was showing the information.

But… it like for there to be a “plants won’t survive this lack of light” option and the lowest it goes is full shade

Every since I bought this device almost a month ago, I haven't been able to use it. Firstly, you can't put it out in the garden at just anytime. It has be first thing in the morning. Secondly, it will only work properly if it's sunny all day. Our weather has been a mix of cloud and sun, overcast part of the time, rain sometimes, occasional thunderstorms...since I've had it there has not been a totally sunny day. This is useless to me.
