The SpotOn Quantum PAR light meter is a highly accurate and affordable tool for setting up and optimising your grow lighting. I tested the SpotOn PAR meter against the industry benchmark Apogee SQ500 ans it is just as accurate for almost half the price.
The SpotOn par meter is developed by Innoquest, a US agricultural instrument specialist. It is also very easy to use and robust, suitable for every day usage in harsh environments.
I was amazed by its accuracy compared to other equivalent sensors which are almost twice the price.

Thanks Shane!!! Your channel is where I send all the new growers I meet when they ask about lights.

[@dertythegrower]

This channel and Apogee Instruments Doctor Bruce Bugbee.. explains and removes all the arguments too with all the proof and solid education on the topic of LED and growing.

[@jeremydesmond3453]

Very cool, another awesome review! Nice to know we have options!

[@PsychonautFPV]

Nice Shane...tnx✌🏻

[@PsychonautFPV]

"I've tested it for two years now, and I must say it doesn't perform well under Full spectrum LEDs with far-red diodes. The PAR reading it provides is about 100/120 PAR lower than it actually is, which is significantly higher. It works well under HPS/CMH. lights However, the upside is that I ended up using too much energy, so I could manage with less energy. So i'm not using it anymore with LEDs.

[@zumbaladin]

Another great tool you found here! Do you have an update regarding the very cheap Uni -T UT383BT Lux meter you talked about 2 months ago as i can't be the only one that bought it :) You then talked about "improving the accuracy with updated calibration for the most common LED grow light spectrum on the market", i'd be very interesting in using this Lux meter with my ES 300, any chance? Or a calibration that would be close to the ES300 spectrum (which seems to be around 2700K?)? Thanks for everything Shane!

Hey, maybe you can do bundle deals where if you buy a light, you can bundle this one with it for 200 euro?

[@DiegoMorales-jh1qi]

I've been watching your videos for years now man💪💪💪💪 I have a small question about spectrum : Does the Sun spectrum looks the same up there in the North hemisphere than around here near the Equatorial line? Do plants react better if the light you provide artificially is more like the kind of light they get in their native lands? Thanks for any input about it man and keep up your great work, you are in a class of your own 💪💪💪💪

That's a really good price but the old watch battery setup would put me off a little. I much prefer a couple of aaa's. That aside. I think the value far outweighs the sacrifice of stockings up on a few CR2032's? Anyway I have a question. I've seen and even purchase a 2000watt (200 watt) dimmable quantum grow light from Amazon for £129. What are your thoughts on these lights please? Meanwell power supply and I'm very happy with it. It also has amazing reviews. Have you managed to test anything along those lines please? Thanks for your help and amazing advice 👍

[@neihc1589]

Hello. Could you see if you can do a review on the Sunraise QB 4000 please. I know u did a review on their purple led light awhile back. Maybe their new lights are better.

[@gman6177]

Iv just got the spot on sensor. Great bit of kit. Instead of guess work, already been able to drop my light and push the girls on. 😁 one question. With the average setting scan mode, is that ok to use that across the area instead of having to take points and work out average par? Seemed to work when I tried it.

[@1114mat]

I’ve been looking at buying one of these but not sure which one to get because they are very expensive and wouldn’t mind buying a Budget one knowing that it’s a good quality at least

[@caniquecanada8375]

Could you please review the photobio advanced quantum par meter by hydrofarm. Thanks in advance

[@AGL_AerialsTampa]

Hello! I noticed that you were testing at the same height but the Spot On meter seems to be 2-3 in taller than the Apogee sensor. Does this make a difference? Thank you!

[@NicholasHowardMusic]

Yeah I’d like to know this too. Especially since the spot on read slightly lower across the board. Will be lower still if those two inches matter.

[@eggspanda2475]

after just looking at an apogee unit for $1500 this is a sigh of relief. no discredit to apogee they are the jedis of the light but for amateurs like me theyre simply out of my league and price range. Also I want that array 8.

What about the apogee 620?

I have a photobio by phantom and am soooo curious if its accurate, its about $150

Thanks Shane, I assume you were adjusting the light height to accommodate the difference in sensor heights?

He used the same sensor for both

[@phdDotCom]

@@justinomar9210 I think you must have misunderstood, Shane measured the same light twice, once with each sensor, then compared the results. But one sensor is taller than the other, bringing it closer to the light and skewing the comparison if he didn’t raise the light accordingly

How do I justify buying any par meter at the very high cost of good meters, but I only use one light? Please advise thank you. !

[@jackknight5697]

Have you tested this meter long-term? I actually bought two of these last year and after about 3 months they both started reading a lot lower than my apogee.

[@volvo09]

Have you changed the batteries? Sounds dumb, but some of this low priced stuff can lack in maintaining performance with anything but fresh quality batteries... even though the display is still clear, or no battery warning is given (even if it has a gauge that still says full). The voltage regulation circuitry on low priced stuff can be lacking or missing. If so, it's interesting to see reduced numbers.

[@jackknight5697]

@@volvo09 Yes, I changed the batteries when I noticed the drop but they still read low. In my expericnce it seems a lot of the cheap instruments I've bought like this are very accurate at first, but tend to lose their calibrations pretty quickly. Get what you pay for I guess.

[@thieutruong473]

Made in china bro

[@frostyfree]

I’ve been using it for 9 months and have seen no drop off comparing it to the apogee 610 . Maybe I got lucky but they all will degrade over time. Apogee can be sent in for recalibration. Not sure about spot on but I can deal with it . On a full sun day take a reading this is your baseline and then it’s just math

[@chriswatson1613]

The spot on metre sensor is about 3 inches closer to the light. How does it read the same as the apogee at different distances Shane?

[@MIGROLIGHT]

test height is from the top of the sensor to underneath the light fixture. Good question though..

[@blackweed3078]

👍👍

[@NicholasHowardMusic]

Hi Shane, thanks for this. How would you rate the spot on against the apogee MQ610 which measures to 750nm?

[@MIGROLIGHT]

Hi, The SpotOn meter is just as accurate but only reads up to 700nm, unless you want to read far red the SpotOn is perfectly fine. Thanks.

[@25Patman]

Photone has an app or android now. I compared the reading to the par chart that came with my light. It was off by only 40 ppfd. Which seems to be in line with what your findings with apple app Photone. Plus I didnt have to use a diffuser. Can you do a follow up maybe trying the Photone with your galaxy phone?

[@25Patman]

Please, I am no pro grower. But I am wondering if its close enough to use it, without fears.

[@timturk1899]

Perfect question! At first, his Apogee didn't, but I believe he got a newer/different model that had larger parameters from UVB up to Infra-red..? I wonder how well it can check for spectrum charts, as well as all the other information that's available through the App, or the device he uses that shows the spectrum peaks when testing lights. I believe that device gets it's information from The Apogee sensor? But that device may have it's own sensor? I'll have to check some past test videos and pay close attention. Heads a bit foggy this morning..? If so, it'd be great to test the Spot On sensor in this way, as well. Your question is Spot On!

[@wesgregg6451]

The Apogee brand meters have multiple sensor options, that cover slightly different ranges of the spectrum, from as low as 370 nm to as high as 750 nm. There are datalogging options. And they have firmware that can be updated in order to correct a discovered issue or (possibly) add new features. The sensors are waterproof and some of them have automatic immersion effect correction (useful if one is working with aquarium lights and such). Apparently, the cables can be extended up to 100 meters / 329 feet. You'd definitely be "getting more" with an Apogee meter. On the other hand, if a person has no need or interest in the features, it would be sensible to spend less on a lesser product that still has the same *basic* functionality. One thing, though: As you stated, it's relatively close in results to the Apogee. However, the difference does not appear to be consistent - you got calculated variances of .01%, .1%, and 2.5%. Of course, there is no way to determine the root of that - the inconsistency could be wholly in the Spot On, a combination of the two, or even wholly in the Apogee's readings. (Or, in theory, I suppose there could have been some kind of variance in the light source between the time you used one meter and the time you used the other.)
