Review: Invaluable tool, quit guessing with your grow lights and outdoor sun/shade areas! - Love love love! This is such a terrific tool and works with no fuss, easy to read. On of my best purchases for my plants.
Review: Nifty little PAR meter - Quite easy to use, settles on a reading quickly, and gives consistent readings with little noise. For the price, this is great. I don't have another PAR meter to compare it to, but based on readings I've taken from other lights that I have quantified, this seems to be pretty close to the $500 meter I rented a while back. One feature that I wish that they'd incorporated would be the ability to use it as a true daylight exposure meter, where you leave it in one place throughout the light cycle and it provides the DLI for that exposure time. Right now the app does have a DLI calculator, which certainly is nice for situations where light is constant, but that is based on the instantaneous reading and the number of hours you enter into the calculator. If this functionality was added to the app, this would be a really exceptional piece of kit.

## Features

- Test PAR | PPFD for any light spectrum accurately. Can show the PAR of red and blue light in light seperately. Blue light is efficiently absorbed by plant chlorophyll. Red light is conducive to the growth of flowers and the maturation of fruits.
- Calculate DLI if the PPFD is stable.
- Record PPFD data at different points methodically by grids and get the PAR Uniformity(Uo). Optimized Growth, ensures even light for balanced plant growth and higher yield.I ncreased Efficiency, identifies weak spots to adjust light placement, reducing energy use. Prevents Light Issues, Avoids damage from too much light and growth issues from too little. The datas can be downloaded.
- Simple and safe APP for test PAR. Quick bluetooth connection.
- Easy to carry the PAR meter.The PAR Meter can be fixed on the drone or toy car to test PPFD anywhere in the greenhouse. No need for the tester to move around.
- Search "compare" in Q&A to see the comparison between VBR-100 and a brand.

### ⭐⭐⭐⭐ Works with caveats
*by P***D on September 21, 2025*

Here's the deal - I found this very useful both indoors and out. It helped me map my greenhouse lighting and the yard for intensity, and was superior to 'phone apps' in this regard. There is a caveat - sunlight intensity is bang-on, within 5% vs weather station predictions. However, indoors under full spectrum grow lights with deep red, or UV, or higher frequency blue tones - this would UNDER estimate PAR by 20-40%. I believe this is due to several factors: even high quality LED light is less even spectrum than sunlight, and whatever equation is used by the sensor doesn't account for uneven sensitivity to spikey spectrums; I don't believe this meter accurately measures above 650nm or below 450nm - no ePAR here; the geometry of the lights, while apparently cosine corrected under some fixed function by the meter, the diffusion panel is not perfect, and can over or under estimate when point sources are used, even if they are distant. This reduces linearity. If you really want accurate measurements under LED, I recommend taking several heights as well, and generating your own inverse square function to characterize your light cone. The cost is hard to beat, and the results are highly reproducible (precise) even if some adjustment is required for accuracy per situation. I would take several close readings in a small area (10" circle) and average them for a truer report. The property angle for best accuracy is directly vertical. If the lights are LED, especially broad spectrum, watch your plants for signals that PAR is higher than estimated - depending on your spectrum, they may be getting half again the photons this suggests. Still, I found this a useful tool, and will continue to use. Phone connection is dead simple and stable. Mapping feature is useful. Outdoors it is directly reliable. I would recommend to the vendor that they include selection of light source modes and provide more accurate models based on the type of lighting being measured, rather than calibrate to solar spectrum only, as this appears to do.
