ViparSpectra XS1500 Pro PAR & ePAR Test and Review

GIVEAWAY DURING THE PREMIERE! Wednesday May 31st at 8pm ET - 5pm PT
The NEW ViparSpectra XS1500 PRO is a small grow light that is generating a big buzz in the indoor growing community! ViparSpectra has bucked the trend we have seen in the last several years and is doing something that most other manufacturers have given up on… They are using Lenses!!! Is it a gimmick or the next great trend in horticultural lighting?
I ran several high sample density PAR and ePAR tests with 144 measurements in a 2’ x 2’ area! I use that fine grained data to do a detailed analysis of the distribution of light. It is an impressive fixture with some big surprises!
ViparSpectra is running great sales on Amazon! Click the Amazon coupon on the product page, then enter discount code DrMJCocoPro during checkout!

you're crazy for testing so much. can't understate how awesome it is for you to spread information like this. thank you

[@papacos4745]

I'm so glad a came across this video. You covered well beyond other people's grow light demonstrations here on utube. I own a 2x2.5 tent & this would be perfect grow light for such a cheap price. Look forward to watching more of your videos happy growing ✌️

[@TRUMP4PRISON2024]

After watching your viparspectra videos a few years back I purchased 3 of the xs1500 with the meanwell drivers. I went with those lights because of Samsung leds and how cool the meanwell drivers operated. You didn’t get much into the driver’s and how much heat they put out but I appreciate the in-depth coverage on ppfd coverage.. thank you for sharing.👍🏽

It would be interesting to see how this light performed compared to itself without the lens cover attached. I think multiple cheaper diodes per watt is the future in LEDs regardless of lenses.

There is a picture on their Amazon page showing the same light par maps with and without the lense panels.

I have never seen you test any lights from Invisible sun LED. . They do an X Bar which is a dual bar array with 301h Evo. Would love to see a review of that board.

hey man, was hoping youd talk about the blue plug cover on the driver, seems you can up the voltage.

I do not recommend increasing the current. Doing so will reduce the efficiency and longevity considerably. Plus there is really no need.

[@polakmay3888]

Cant wait ;) Wonder how to import it to EU with reasonable price as it seems even previous version of this lamp outscales other lamps available here

[@sixmillionsilencedaccounts3517]

I'm from EU too and I want this light so badly for my 2x2. The problem is even original XS1500 isn't available here. Only XS1000 and XS2000 which sucks. XS1000 is not enough. Maybe XS2000 could be run at 75% but it seems too big for 2x2, it's more suited for rectangular space like 3x2.

[@polakmay3888]

How do you think 2 of these in a 1m x 1m or 3.3ft x 3.3ft tent?

[@seranne]

So when growing with this light you have to respect the height at all the time and play with the dimmer along the grow?

[@jigglepuff1218]

Yes

[@wizard2755]

Is it worth using this on a shelf grow set up or just in grow tents?

[@newmexicocannasprouts7627]

You would be safe using it in a shelf set up and dimming it to where your getting the right amount of par for your needs.

[@zebulonreynaud919]

the only problem with this is there is no full flexible dimmer, it's a shame. i would use only 162/176 watt for a 2x4 but i can't if i buy 2 of this. with no flexible dimmer il would be limited at 2x75watt (wich is too low) or to 2x110 watt who is too much electricity, this fixture is perfect in every aspect for a 2x2, but not for a 2x4 because of the absence of flexible dimming.

[@Oscar-gq4ro]

I’ve got their v1000 in my veg tent. Solid little light for $50

[@EXTREMERC416]

As of february of 2024 the xs1500pro no longer comes with any samsung diodes. Some claimed it came with m281 i believe and some with meanwell powersuply in 2023. Now its a sosen driver. The early models in the manual specificed the m281 leds. My manual doesnt. But its definetly more powerfull and better par than the xs1500

[@slpardee10]

Absolutely fantastic! I now have incredible data on my new lights. And a confirmation that it was a great purchase. Thanks. PS Looks like I should hang the lights about 13" above the canopy for maximum consistency and adjust the dimmer for the ppfd. Only shame is not having a variable dimmer. That would have completed the coup de gras.

[@GodOfThunder6789]

Any thought on running 2 of these fixtures in a 2x4 grow tent?

[@LindoGringo833]

xs 3000 pro

[@slpardee10]

Perfect in a 4 x 2. Manual even shows how far apart to space the lights for perfect coverage. The new XS 3000 Pro is just 2 of these with bars connecting them and one removable driver for both. I prefer using 2 XS 1500 Pros because they can also be used separately in 2 x 2s.

[@jimjones6421]

I have 3 in a 2x4 tent at 75% for flowering

[@slpardee10]

@@jimjones6421 Jim, you only need 2 in a 2 x 4. Three will cause a light overlap with plant damage. That happened to the Maine grower on his youtube channel. That is why the instructions say to space them 9.4 inches apart in the 2 x 4.

[@slpardee10]

[@Goatex100]

Ok, I’m a bit confused. The Samsung diodes on their write up, claim they are using lm301b. Actually using lm281b….so, your saying it’s an awesome light, however with these diodes, does it really make a big difference? It’s a good price, does anyone have some info for me? Thanks!!

[@christittle1131]

The lens are helping these leds direct their light better. Wish they would have used the new 301h’s in this light. But by using the lens and allowing them to use cheaper led’s u can buy this little power house with discount code for $88! It makes this tiny light one of the best grow lights for the price, and not just a opinion when u measure it out it’s .30$ I think.27$ cents is the cheapest Best Buy light there is. So vipar spectra was really close to having best deal of all time. U usually have to buy a big light to get a deal like this. I bet vipar spectra is kicking their self for not using the best led in this light and won that title of best money light on the market. But better leds might have drove prices to high

[@SeanEidt]

@@christittle1131 Why dont they just put the lens on the original xs1000 and xs1500 with the samsung diodes and meanwell driver?

[@Trailblazerz710]

I see they also offer a XS 2500 which is two of the 1500s connected. Based on your data, it would also be a good option for a 2 x 4 also correct? Another thing that would be a great addition to your reviews would be controller compatibility .. will it work with the most popular environment controllers… VIVOSUN and AC INFINITY controllers. Both of the devices are compatible with other lights, but it would be great to have someone verify that they work because there are some reviews of certain lights that say they work with the devices but when people get them in hand and try to plug them up, they won’t even connect. Great reviews are a lot of information

Эта лампа феноменальна, так как многие используют свет 500ppfd. И за копейки можно или 2*2 осветить или 3*3 для не требовательных. А если все плоды будут на площади 2*2 а в свободном месте листья и вентилятор, то это самый дешовый свет для 3*3 гроубокса.

[@dmo848]

Yeah but how hot do they run. This is something no one ever talks about. The light can be great but if it runs too dang hott than i can't mess with it. Hot lights only work on when they are all the way at the top of the tent so the inline fan can take that heat out

1 - Your number grids are so 8-bit (visually simplistic). Consider dropping the annoying, green, blocky background with a more modern style heatmap. Look up 'how to create heatmaps in google sheets'. Not only will it look more pleasing to your audience but you'll see data relationships that were previously unseen. For example, you'll gain better insight on how the lenses are directing light. 2 - No need to rely on manual, inconsistent and time consuming sensor placement if you put female divots into the tent floor and a male divot on the bottom of your sensor mount... hand in glove! 3 - When you show results comparing the standard sampling density (SD 16 samples) to the high density sampling (HD 144 samples), the differences between the two are only 4%. Why do you represent that as "significant over measure" and "unnerving"? 4 - In the chart comparing dimmer settings with actual watts drawn you state they are "accurate throughout the dimming range", but the 5% dim setting draws 9.5%, 90% higher than claimed! 5 - About your HD sampling, standard deviation comparisons between the 12 and 16" SD and HD samplings show there is minimal insight to be gained from the added labor, video bandwidth and viewer time commitment. From SD to HD 12" the StDev% drops 0.1% (3.5 to 3.4%) while the 16" drops 0.4% (4.9 to 4.5%). Granted the HD technique can help you figure out how the lenses are pointed, which I understand to be your motivation. Not a wasted effort and good to keep in mind going forward. 6* - What's the basis of your claim that 1200 PPFD is too much light without C02 supplementation? You also said about the MedicGrow Fold-8 at 1000 PPFD, "Full power is too much light for a 4 x 4". I would make the exact counter claim based on the direct and current growing experience of myself and others who routinely get 2 or more grams/watt in ambient CO2 and >1000 PPFD LEDs, as well as studies showing peak growth between 1200-2000 PPFD. Considering the reach of your platform and the authority you hold, I find these claims contradicting available evidence. BTW, this is how data analysts spend their retirement, squawking when inconsistencies smack them in the face! ha :) * Morrison 2021 - "Cannabis Yield, Potency, and Leaf Photosynthesis Respond Differently to Increasing Light Levels in an Indoor Environment".

Thanks Einstein!

[@curiousbystander9193]

you have corrupted your comparison by using 14.5 inches compared to 12 with the new xs, just sayin'..... you may not have seen as much perimeter effect at 12 with the old one.... and clearly the 2+ inch difference made of difference in Par readings..... anyhow, like what you are doing here and your methods are generally much better than most, so thanks. kzbin.info/www/bejne/bqKlimWYebhqldU

[@DrMJCoco]

Keeping the maximum ppfd the same allows better comparisons than keeping the height the same. Trying to compare tests that have different maximums would be more “corrupt”. I understand your point but stand by the decision. Glad you like the tests and appreciate the feedback. Grower love

[@curiousbystander9193]

so, you are saying you get max from 14.5 and not 12.5... is that what you are saying? Either you are losing me with your reasoning or I'll be losing you... I'll try though.... seems to me only a fair comparison would remove the height variable..... unless you are saying, for the xs 15 you get the max from 14.5, which really doesn;t make sense as you'd get more from 12.5, but anyway @@DrMJCoco

[@curiousbystander9193]

would it not help the most to know, in this grow, when lights are 12 I get X, and at 14 I get Y...... based on your distribution mapping, inside of 2.5 x2.5, who cares, limited variability now with the lens effect in the new xs..... you get my drift, I hope@@DrMJCoco
