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 ✌️
The only thing you could have expanded on was getting numbers in a 3x3 tent which they actually reference for a VEG stage. I bought one of these for their 4/20 event sale and it is awesome to see such an in depth analysis. Great job.
I am using this for my first grow in germany :D We just decriminalized 3 Plants but can only harvest 50g Dry XD Still its something. so we grow for quality only scince Jields arend that big of a deal... If i ever make a growing video i wil link ur vid in the description of my gear. They really semm to have figured it out at a great price. Now the only thing to optimize (technically) is efficiany.
I got the p600 updated, very happy with the price which was half the cost,the diodes configuration and output for drawage ratio,gives this light a run for it's money at half the cost.it couldn't lay a glove on this light for coverage though.
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.
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.
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.👍🏽
Great content as always! I got your book even tough your website is a treasure of informations. It would be great to see more grow content on this channel, for example a video about identifying nutrient deficiency or other issues related to fertigation.
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
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.
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
Dr MJ Coco ur the man. Very much enjoyed your site. Viparspectra is a brand I've been keeping an eye on, Kingbrite too. Any other suggestions in that range?
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.
Looking very similar to the Lenses on Sanlight Led Lights. And they Are one of the best on the Market. Really looking Forward to See this light in the european Market. Thanks for the Video. 537
New sub. I have the green Viparspectra lights. I have a grow room too. And, I bread new beans. The plant in my thumbnail picture is my Orange Crunch Cake.
Thank you for all the information you provide and your channel is awesome! Love the content please keep it up. If I win this light I’ll give it to my less fortunate friend that can’t afford it. I recommended it to him and he has a lot of cheap Amazon leds but this would be perfect for him thank you 😊
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.
Nice testing ! I would have been interested in how the light performs above the 60x60 area, because I would like to run it in a 80x80 cm tent. Would you recommend for this size ?
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
Too bad it cost over 200 euro here in EU, so I got a proper light for 270 euro Phlizon FD4500 450W 1728 Samsung lm281b+ 6 bars from their site. Just better value. But at 88 dollar i would get at least 2 of these!
I’m debating on getting the Aglex m400 it’s the 2x4 version of your light they claim to have ur and ir… I was curious if your light does? I had the Aglex con 3000 … it was a monster light pushing over 600 watts ! That’s what has me on the edge of trying ther bar lights … that 650 u got lookin nice 👍
lights are doing jumps and bounds in efficiency,but the genetics is still 80% of the final product ,so many focus on grow gear and fail to focus on the genetics
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!!
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
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 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.
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.
Yeah In america cheaper Maybe customs in Europe make them pay more or they stealing us I got it for 150€ but i have to bid in auction If not 199 like you sayd
Thats what im wondering. Ive heard the old version had superior diodes and driver. The new one just has the lens to focus it better. But they are saying the pro version runs hotter which isn't good for me. Anyone know more about this?
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".
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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8qBY2bDS7_s.html
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
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
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
