This is my new favourite CZcams channel, I love that there is someone out there doing these tests, its what ive always dreamed of. Thanks Shane.
I like how you have the driver remote on the Migro, the design is thought through very well, impressive little light!
I was tempted by these, was about to buy then remembered you had reviewed them , you saved me some money cheers
Migro, awesome videos and awesome lights :)
I've been seeing these on big clives channel. I'm glad you did this. I was curious about them
jPapapot same hahaha, a bit sad though to hear how crap they are
I sure do appreciate your videos, and the method you use to teach is very knowledgeable, and helpful keep up the good work!
the best review, a lot of usefull information, I loved it. Thank you!
Thank you for sharing your knowledge and improving mine!
great info always backed with tests !
I swear one more video like this and I'm switching to migro. I've always stayed away because of the price but this really shows the difference
Dont be so easily fooled by migro
I have a cool white one on a cpu heatsink/fan combo above my work bench. Makes great task lighting.
Interesting stuff
Tnx Shane ! Take care! Peace ✌️ from Welland Ontario Canada 🇨🇦
Thanks Shane! I'm saving up to buy a micro light for my next grow! Using a Viparspectra Reflector 600w this time around; fingers crossed for good results!
You should consider chilLed.com his youtube is growmau5
Cool. You can run the Vipar and MIGRO led together. What size grow area are you using?
@@MIGROLIGHT 2.5ft x 3.5ft
Good stuff, keep it up
I bought a load of these some time ago (advertised as Full Spectrum) and i did connect one up - but i was worried about safety as it got really hot - added a heat sink but i think I'll use them in the garage when i get around to it - since bought the Mars Hydro TSW 2000 using it in a 120cm x 120cm tent but only using a 80cm x 80cm area as i have a turntable set up - can access the plants better that way...!
Wish i found your chanel sooner - enjoy your videos - best wishes from County Donegal....!
I'm so glad i found this video, i want to move my plants indoors for the winter and was thinking on a cheap alternative for growlights, guess i'm not buying those
great vid
I use one of these on an old computer heat sink for my seedlings in a 1x2 mylar box and find it works just great. But for veg and flower I have a much better setup but for something cheap I use 4 weeks a year this is perfect.
I used to borrow 2 2ft T5 bulbs and this is not as good probably but I'm happy
For little seedlings the blurple one may be a good spectrum. I hear you can get accelerated growth in very young seedlings with lots of blue.
@@MIGROLIGHT that's exactly the one I have. And I've learnt so much from your videos thankyou from canada
ty
Have two 200w 3000k bars I use to supplement flowering and want to dim them
Hello Shane< Again, another great/informative video. Keep up the good work. Question: I have 2 sets of Secret Jardin 26w TLEDs as extra lighting/high noon [yes, set to go on from 10;00-14;00 o"time), BUT lighting from beneath/upwards.. how could i measure the par/ppfd there, and if it's too close/too much lighting??
Great video!!!!. What do you think about CREE COB LED Xlamp (any of them) ?
I'm doing the exact same thing, I should probably make a vid whilst the plants are still young
I should, i would, i could...
Did you then?
Test the HLG 550V2
I was almost about to buy them. Thanks for the info it helped a lot
I have a single cool white one on a PC heatsink with a fan. Pulls about 65w from the wall. Works ok as a veg light. Wouldn't want to flower with one.
I have work with the warm white ones, not those exactly but they give me good results un 2x2 with 200 watts. It would be great to know lumen output to see if the maker is lying wiht the efficiency, they have an output of 4500lumen each in AliExpress...
Lumens?
down load a lux meter on your phone and whatever the lux reading is divide it by 76 that's a fairly accurate par number without a fancy meter
Lux meter app dont read more than 1000 lumen, more than that they saturate and don take a good reading.
Please
@NukeHeads 3 I´m talking about the maker speecs not grow science, i want to know if they lie in their speecs or not. Sorry by the spanglish
Nice review. Wouldn't mind you testing the quantum board on aliexpress.
Good video but what would be a good solution? I dont have $300+ to buy a good light so im looking for something affordable.
Can you do a comparison video on the migro 100 vs the cheap X6 sunshine spectrum COB led fixture found on amazon.
curious, is green is in the middle of the light spectrum? seems so
It was on 30 cm. And we got the average par value on the table. How much was the peak value in the middle of the table directly under the light?
Their great for veg, my plants like the ones I built. The trick is to include some sort of dimmer or it'll burn out in like a month
How did you dim these?
If the cob was run with an external driver, would the results be different?
Did you cool down the back of the LED with some heatsink?
So can you wire 7 of those warm white leds in series or to one power source, poss 8 with a dimmer??
I have setup a solar electric power system. Is it the driver of the chip a transformer. And would it not be more effective and a better quality light to use a driver chip without a driver to supply the chip direct from the solar battery with the required voltage for example 36v. That can be achieved by 3 12 volts solar batteries in series. Or if I upgrade to a 48 volt lithium battery with a dimmer on to tune to the required voltage. With a driver chip the current have to be dbl transformed with seems a bit unnecessary?
What tipe of dimmer would I use on the slightly bigger more square solderless dimmable cobs?
Test the alibaba quantum boards that claim to use authentic samsung diodes. If their description is honest, they are by far the most value for money grow light
οκ I know right they have the same parts as the hlg so why wouldn't be the same... It should be
@@joshamy39 do u guys even understand what Alibaba is they sell knockoffs or Chinese stolen plans and then find the absolute most garbage left over diodes from Samsung's throw away pile or non top notch performing gear. It's like getting nike air maxes from the corner store. Also like shopping at Marshall's or TJ max sure it looks ok the first time u wear it till u find the flaw in stitching or holes or just messed up in general. But hey it's ok u just gotta buy a new one every grow or 2...
J&A but diffrent boards yeah it’s similar
greenghost3737 you are probably right but Id like to see migros test to believe it
@@greenghost-xi5jp It's also where Nanolux and Growers Choice buy. At least Growers Choice use Lonbright(Longhood?), have changed name slightly. I have a great Low frequency, square wave ballast with digital readout, dimming, and boost, no fan, I-64(?) waterproof approved, from Ceramic Solutions lighting in N. Cali, and they/he buys through EBM in China, I believe. Last time he had 630W DE-CMH ballast(same as above), w/double ended lamp for $199, shipping included. So I bought another set! Impressive! He even gave me the newest 3K-R improved lamp, just to try out-Colin is great. Much like Shane, here! I've heard certain provinces are much better, higher quality, while some areas are known to be lower quality, etc. They do have their own patents, and very smart designers, creators in some areas. But, yeah, I have seen exact copies of products specifically in the USA. Sun Supply AC/DE fixture is great, and expensive, but Lonbright has totally copied. That's who Growers Choice gets their CMH equipment from, and they'll label them with Growers Choice emblems, whatever they ordered. This has been done often by big companies. Alibaba gives us regular people these same deals. I was going to upgrade to a 1000W DE-CMH, but only available in 220V. Adding about 400W(5x5 Gorilla tent), but 4-100w Migro lights would give a much more even lit canopy, and the adjustability and craftsmanship, Luminous COB's, most efficient. I had disability back pay coming, ended up a few grand less than expected. Looked all over Alibaba, different COB setups everywhere. Finally found 1 company that makes 100W COB units using 2-50W COB's each on a 1M rail that the COBS can be slid back and forth, as well as turning 350°, and can be angled 180°, which is working well. These only had Citizen CLUO48-1212 COB's, less efficient than Migro's Luminous COB's, and cheap, but workable, but craftsmanship is low compared to Migro, but hopefully stays functional. I still prefer mostly HID lamps, but COB's as supplemental is great. Shane's Migro are definitely higher quality w/better workmanship, as well as better efficiency. And upgradable if better COB's come out. Sorry for rambling on. Migro are Tops in COB's! Leaders for awhile now, and into the future I believe!
samsung lm301 or 561 what I can't hear you?
What is the difference between this F6040 Warm White and F6040 Pink?
So what's the recommendation. Stock up on halides whilst we can get them?
Actually those Cob LEDs get better if you cool them right, i watercool mine and i am very happy with them.
It would have been nice to see the $/ppfd and the ROI for Ebay chips Vs Migrolight ones.
Ebay white LED (cheap to buy, but require more electricity)
MigroArray2 (expensive to buy, but use less electricity)
Question: how many 8 hours days should we wait before we get the same price (buying price + electricity) for a similar ppfd?
My guess would be that Ebay chips will win by far.
Could you test done kingbo led grow lights some think there excellent some think there crap perhaps you could debunk then 👍 great video, as expected the eBay cobs are abismal
I've got six of the blurples hes testing and four of the whites. i used one blurple on a seed which grew to a foot and a half tall. Didnt look any different to any other seedlings. But I got a migro 100 and could just turn that down, then up as it grew. Now I[ve got six crap 50w cob lights (tey pulled exactly 50 from whall) and 1 300w and 1 1200w chinese knockoffs of mars hydro. So all for the fucken bin!!! Aaarrgghh....one piece of advice for newbs. Never buy cheap stuff. You[ll cry in the long run. If des0perate, get some cfls. But best advice is to save, and buy once. Also got full HID gear to dispose of. Another fucken waste that was. I got migro aray 4, plus the migro 100. Perfect for me. Good luck guys
!
So its bad?
Hi there I've got an old led 600 watt I'm thinking of trying to make a new one out of it by changing the leds it's got5 watt leds and is around 60cm x 60cm it was at the time a good quality light but for me it was just too much bright red colour for me so it's just been sat in the box since is there any way I could do this any help from you or a sub would be much appreciated thanks
The peak blue spectrum isn't centered at 450nm like most it looks like 425nm
Is PPFD/W a real thing? Always thought it was PPF/W. Can you check on that?
I have a cool white one on a cpu heatsink/fan combo above my workbench. Makes great task lighting. Cob is rated at 50w but my meter shows it draws about 65w. Also have some warm white and some full spectrum blurple one I thought about using in another project but given your review of them I may go another route.
Re-watching some of your vids.
I'm curious, you mention the leds being improved but given the simplicity of the driver the power factor must be feckin terrible.
I get the LEDs won't be great but surely most of that inefficiency lies in the driver doesn't it?
The driver is probably about 70% efficient vs 94% for best in class. The LEDs used would be just as much to blame for the low result. They are only a few Euros each after all.
would you test this to see if it is good for Hopoocolor HPCS300 Mini Spectrometer Handheld CRI Meter for LED Light Tester with Software
Test the chilled
Hey mate. I was wondering if you could test a popular grow light on Amazon called the CrxSunny X6 (or X5). All that the data says is that they use Epistar full spectrum cobs.
Best Epistar led light I've tested is about 1.4umols/watt efficiency. Not really worth it in my view. CMH is just as good...
@@MIGROLIGHT thank you for the reply :) I wonder if it being in a cob format would help push up the efficiency a bit?
Hi mate, good work,
you say you took the measurements on 90cmx90cm at 1min40sec and at min 4 you present the results on 60x60cm. Also could you pls try the measurements with the lens on and off ?
The grid was 90cm x 90cm but the PPFD readings were 0 outside the 60cm x 60cm area. Lens on/off will differ by about 10%
Considering they only cost a few quid and you dont need to buy a driver...ill say they're good enough for some one doing a micro/stealth grow even if you need 7 for a 2ftx2ft grow
So the purpose built "grow light" will grow plants worse than the general purpose white led.
There is new models of there COBs .... maybe better ?
Test a HLG 550 v2 hell light .
I have a hlg v2 on its way for testing
Please test or speak on the skyline led.its a fanless light.ideal for stealth.Id like you opinion as im tempted.
Just purchased the 200W MkII Model.I'll test it and post the video when it comes in. Thanks, Shane
@@MIGROLIGHT You are a legend.Thanks for all the great info.I will be watching.👊🏻
@@MIGROLIGHT it's so great you spend your money and get these new grow lights that come on the market and test and share the costs and result comparisons. Question. What do you end up doing with the lights when your done? Sell, use, give away?
i thought these would do ok
Are you sure your meter is reading red correctly? Both your tests look exactly like the sellers advertised graphs but with the region of red light's intensity reduced by 50-80%.
Just to follow up. I did a really half-assed spectrum test (photo of light on flat white background analyzed for RGB), and R/B were virtually identical in perceived intensity. Not exactly scientific, but I don't have a $500+ spectrometer. By contrast, your readings look to be about twice the intensity across "blue" vs "red". My cob however has that "red led" coating you point out on your blurple unit completely covering the leds (I've never actually seen one with that cutout before, 99% of the ones on eBay US are like mine... which would explain the increase in red spectrum at least partly. If you get the chance please drop another $2 and try one of the more typical style. You could also pick up a pure red unit (rarer and a different (looks older) style, but available for about $3 instead of $2) to see if it could be used to balance out the blue-heavy nature of the "full spectrum" without introducing an excess of yellow and green light.
I'm also curious about your reflector? I've never held one of your unit's but it appears it's built into the lens. How efficient is it at working with these cheap, backed cobs? As they scatter light in a very nearly hemispheric range without a reflector. They are often sold with a very cheap aluminum/plastic reflector/lens, and I'd be curious to see how that setup compared when used with them vs your setup.
the 50w label stands for equivalent 50w incandescent or that draws 50w?
I Have ordered A 50w white full spectrum. Havent tested the wattage. but buddy it will damn near blind you!!! So it's up there ide imagine
Almost forgot, yes they will grow. Anything.
Ярко светит?
I want one like that led for 1 plant under 6$
Nukeheads is putting 10 of these on a sheet of steel and trying to sell it for 500 bucks lol
Not the same lights.
@NukeHeads 3 what a f**king knob head.....fuuuuuuuck bro....your head is so far up your own shit tube its unreal.....fuuuuuuck
Is that fixture submerged in that fish tank??!
Could you please test. The bloomspect 600 from Amazon
No need. They are excellent. I have 5 of the older larger version they quit making a year ago. And 3 of the 300 watt version. They kick ass seriously. Only downfall is you need 24" distance away. Way to powerful.
I wish I could take my bloomspects apart and spread out the diodes more. They are great for growing dense buds. But get a par meter, or keep 24inches away on 600. And 18"-22" for the 300. The 300 watt models I like better cause you can add more and spread them out. I'm getting good results adding the maxsisun 480 watt models to them and throwing in some 3,000k & 4,000k & 6,000k cobs in the mix also.
@@shakascloset1700 dude I love these lights I have 2 in a 4x4 tent I just started a channel my self you can check it out @D nava420n I'm currently building a veg light for my starter closet hope to post the results it will be using 2 50 watt chips like the ones in this vid this little 100 watt sucker is brite.
Not true.
I have those lights and the plants are great.
i would like you to explain too me how blue light is the least powerful for photosynthesis....
EVERY single photosynthetis animal (almost every coral) in the sea relies on blue light almost soley and at par and pur levels a plant would burn under!
your description is wrong imo...
Blue light penetrates water better than other wavelengths hence why those creatures rely on the blue wavelength.
Only 14 ppfd for 48w? Very strange results, i have almost identical leds bought via Aliexpress and i've achieved acceptable results for young plants. For sure they are not professional but if those values are correct i couldn't have grown anything.
Do the part numbers match? You can see the numbers in the close-up. I'm sure there are many variants out there.
@@MIGROLIGHT Nope, DOB4075 (bridgelux). Can i ask what instrument (multimeter?) you have connected to the sensor to read the values (divided by 10) in that display?

now thats something ! real nice thank you for that been thinking about tinker up a light fixture with cobs But Now il definately Not tinker up one im pushing for the cfls and storebought led ramp instead and pay those 100 £ instead for a premade . For vegetable growing actually not cannabis anymore ! / Paul Roger
Really bad leds, did you ever tested good chinese or cheap led? But where to buy a luminus cob led like in your migro?
Excuse my english
No problem:) almost all major brand LEDs are made in China. Cree, Luminus bridgelux etc. You get what you pay for.
Why put a lense over them?
COBs are more efficient with lenses. Otherwise the light is projected at a 150 degree arc.
@@MIGROLIGHT why 150 degrees? its not 180 ???
completely irrelevant. *do you have juruparris in the tank?* looks like it but unsure.
You should test the ming & ben Grow Plant A/C 120v COB I got around 40 par 53 watts almost zero green in the spectrum but way better than these you tested and they where only $.75 per one 53 watt COB.
Can you post a link

You could buy a lens to go with the white led and it would bring that number up alot got Love $2 a peace tho
As I understood the video they were tested in a MIGRO fixture with a lens, so I don't think two lenses would bring the numbers up more but maybe would make a nice telescope...

Meh
Yxo Full spectrum cob
Your te sd t is terribly skewed on these led Cobs. Do your numbers on a 1.5ftsquare area. You have to know you used too large an area to test a 50 watt chip. You skipped right through it. That ain't cool, shane...
But why would you use a 90x90 Area to measure that kind of light? I would measure it just directly under it. That Area is way to big. No one would want to light this big area with just a 50W Chip
It's to capture as many photons as possible
If you cross Blueberry with Purple Thai, you get Blurple Thai.
Check out NukeHeads.com, Cody has built some awesome grow lights, totally American made and not these cheap $2 lights, there voice activated and working on chassis and liquid lens....They put out an awesome spectrum and alot of par.....

I have grown great results with alot of other companies and for the cost and how I use it it kicks ass. I use it with hydroguard and sometimes other additives. But it really can be used as a stand alone all in one nutrient. Works great when adding any company's sweetener.
The Muckler yeah bro, unfortunately some things still have to be sourced from China, I own a construction business and over 80 percent of the steel comes from China or India and it’s junk, you can blame that on Obama giving away American jobs to the Chinese, but everything else Cody uses is American made and built in America, by Americans...

lol 740w for a 2 x 2 hahahaha thats insane
Esos chips dan solo 60 lúmenes vatio y no están diseñados para estar encendidos mucho tiempo, se utilizan en vías de paso con un volumétrico que al detectar que vas a pasar enciende el led y cuando pasas se apaga. Es de lerdos que monteis eso para los fines que los montais algunos.
I think Shane has skewed the information on this. If you were wanting an input of 35watts per square foot, that'd be about 1.5 foot coverage on an fifty watts. Shan has chosen to test fifty watts cob over a four square foot area. This dillutes the results, therefore hiding the actual efficiency of the cheep cobs. I see lots of praises for the useful information on comments. I actually don't appreciate skewed tests that are obviously skewed to keep the driverless cobs from being competition for him and other producers. That's not scientific or responsible testing. Shame on you Shane. You should redo the tests to redeem yourself in the eyes of the people I've made aware of this.... Adam Bennett.
I don't get why would anyone buy a migro lamp. Crazy expensive and definitely not the best out there.
It is a bit pricey. But when you calculate parts and engineering and location of manufacturing and shipping costs. Its actually a nice light. And remember the stuff it grows will pay for it in no time. I would love to someday soon at least get one. But would love to own 4.
