We get a lot of weird mid day shaded areas in my backyard so I wasn’t sure what qualified as full sun areas or not, this has already been extremely helpful to know where I can plant things. I just go out near it, open the app, hit the button and I can see all the data on my phone, it’s really easy to use. Review: Bad product; can't read results - This item is beyond the return date but I wanted to let folks know my experience. The item didn't come with instructions on what app to use to get results. I got a response from the seller and downloaded the app but the results will never show on the app. I've taken my phone out there and clicked the button on the device and see that there are results from before I bought the product but no new results come in. I wish I wouldn't have given it the time that I did to see if it worked and would have returned it in time. ## Features - Quantify the total amount of photons received by plants per square meter over the course of a day. The unit is mol/m²/d (DLI). After connecting to your phone for the first time, the meter automatically records daily DLI values.

We get a lot of weird mid day shaded areas in my backyard so I wasn’t sure what qualified as full sun areas or not, this has already been extremely helpful to know where I can plant things. I just go out near it, open the app, hit the button and I can see all the data on my phone, it’s really easy to use. ### ⭐ Bad product; can't read results *by S***L on August 3, 2025* This item is beyond the return date but I wanted to let folks know my experience. The item didn't come with instructions on what app to use to get results. I got a response from the seller and downloaded the app but the results will never show on the app. I've taken my phone out there and clicked the button on the device and see that there are results from before I bought the product but no new results come in. I wish I wouldn't have given it the time that I did to see if it worked and would have returned it in time. ### ⭐⭐⭐⭐⭐ Great tool for inquiring minds - and my cacti approve! *by D***G on July 19, 2025* I have a few racks of cacti on my deck, and I wanted to make sure they were getting enough sun. Visual observation is helpful, but I'm not willing to spend the time to get detailed data that way. This handy little gadget does exactly what I need! I recorded several full days at different locations on my plant racks and gained a clear picture of which areas get the best light. The results it provided seem to be accurate and consistent with my observations. I was surprised that the second shelf from the top really doesn't get as much light as I thought it did - lesson learned, and cacti happy! I found the app easy to use. Folks, don't confuse this gadget for the ones that cost 10X as much and connect to the internet - of COURSE you have to get within bluetooth range to download the data! When I want to upload the data to my phone, it's a simple matter of pushing the button on the sensor, going into the app, and choosing the device. The data shows up on my phone immediately. It's super easy to understand the chart, and if I wanted to export the data in a chart for further analysis, the app makes it easy. I love this gadget! I'm enough of a science geek that I keep it out there and check it every once in a while, because I'm curious. If you're data-driven and curious, give it a try. ## Frequently Bought Together - VBR-20 DLI Meter,Full Sun,Partial,Shade,Record Long Term Daily Light Integral,180 Days,MOL/m²/d,can be exported as a File - 4-in-1 Soil Moisture Meter Digital Plant Temperature/Soil Moisture/PH Meter/Sunlight Intensity Backlight LCD Display Soil Test Meter for Gardening, Farming and Outdoor Plants - AH-20Plus DLI Meter.Full Sun,Partial Sun,Partial Shade,Shade.Sun Hours.Sunlight Meter for Gardening,Long Lifetime --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/593994133-vbr-20-dli-light-meter-for-plants-measure-full-day](https://www.desertcart.co.za/products/593994133-vbr-20-dli-light-meter-for-plants-measure-full-day) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-04*
