I had a nightmare start to my first grow, my LED i purchased didnt work so sent it back and bought a MIGRO 100, had to wait due to back log that cost me another 11 days but its clear to see after day 65 my plant absolutely loves the light. It was a blessing in disguise. She is booming or should I say blooming! Shane is an absolute top top guy and this is the only light I will ever use from now on.

[@torrielandsman4625]

With all the research you put into LED technology it would be nice if you would put a little thought into how to improve the numbers you put up for HID lights, Because I know that the setup I use with HPS will blow away the numbers you are showing to represent MH,CMH and HPS simply by using a true parabolic reflector (white not metalic) with the bulb properly focused for the footprint you are trying to achieve.

[@michaelrostine8033]

Thank you very much, me being new to LED's I've been looking for just such videos👍

[@timturk1899]

And spectrum is KEY! The blurple LED's give some okay PPFD's, yet the spectrum is very unbalanced, missing many important colors. Same thing with HPS. I think what's most important is spectrum and PPFD. Where Migro is great all around. But what if better COB's are released? Migro can upgrade your system! That, and the craftsmanship are why I'll pay double the price of a cheaper Chinese alternative that does less, anyday. And from what I've heard, great customer service! Thanks again Shane, for the great video!

[@MIGROLIGHT]

Thanks. We'll use the best cobs at the moment. No sifn of big developments in efficiency over the current generation yet but when it happens you will be able to upgrade. Thanks for the comment. Shane

I really appreciate the video. It comes across as genuinely unbiased though you do not hide you have a dog in the fight. I love raw data when making a decision especially if collected by someone knowledgeable about typical procedures for repeatable testing. Postings by others say they get similar numbers giving me more faith in the data. I know testing all brands is impossible and hopefully you did not purposefully exclude competitors with better performing products. Thank you for this video and I look forward to watching your others. I will likely buy one of your lights because it is modular and to support this channel. I'll likely buy the Fluence as well for my 4*4 test room.

[@bennielamb8911]

Good video. All about the efficiency. I did see another light by chilled that looks very good for efficiency too

[@MIGROLIGHT]

I had a look. They publish PPFD charts so it is possible to work out PPFD per watt. I'll post something if I can

[@davidbrandenburg8029]

for what the electricity cost is on those MH and HPS lights, you could replace a 1,000w hps with 3- 1,000w LED light panels and still save money and have 3 times the ppfd!.

[@goonernumone8444]

Dude a 1000w is a 1000w regardless, its like a pound of lead v a pound of feathers, still a pound in weight, but yes the Electric sky ES300 ( its 300w from the wall) 3 of these draw 900w but they have a efficiency of 2.0 so each light puts out about 60% more light for just 300w, use 3 of them and youll have a much bigger footprint and youll have over 60% increase in out put per watt AND what 3 times ( if not more).the footprint, whats wrong is when companies use words like 1000 or 2000 ( like spider farmer and mars hydro ) when they are really 100w and 200 watt, the biggest wattage draw for any led is 600 watt to my knowlage, after that they stop getting brighter and start getting hotter so you just use another unit!

[@plantsofamerica1756]

Super helpful, super informative, exactly what I needed to make better purchase decision. Thank you!

[@joegarnier3716]

It would be interesting if you compare these lights to a really basic do-it-yourself project. A friend of mine has a light consisting of 32 fiet 90+ cri LED bulbs. 17.5 watts a piece rated at 1600 lumens. He has a mix of 5000k and 3000k. 4x4 grow space. He gets pretty good results, but I suspect the drivers are less efficient than something with an independent power supply. Either way, for less than $300, soild value for money in my view.

[@manuelabongreiniger5128]

Not having fans is i think a big helper for top LED lights. Coming from PC building i remember a typical 12V fan is roughly at 10 Watts power draw per piece. If your light has a couple of them it spends a not small % of power with getting 0 par for it. Maybe you could test on a few lights, disconnect the fans, take power and par measurements before it burns itself to death. Or just unplug the Fans run and Measure power assuming light output will be the same. I wonder how much closer some Lights would get to that magical 2.0 number. At least it is more fair against HPS etc. Those also will need some cooling/Ventilation that the LED is having on board and i think is not weighted in. Top LEDs sort of "Cheat" because not only are they more efficient, they require no fan because they stay cooler and that helps in keeping the power consumption as low as possible.

[@FreedomVsAron]

Thank you for the numbers first of all but i can only take these with a grain of salt. If you have 1 light source but super high ppfd it comes down to really poor light spread with hotspots and the edges where these kind of lights drop significantly. Hanging for example a nicely build strip panel closer to the plants is probably the better enviroment to grow plants since u let the plant photosynthesis evenly and u have less hassle trying to train them since they grow to the light and avoid stress. I wish transport wasnt an issue, otherwise i think we would see much more units using strips. I feel like for the best grow light there should also be a category for what light spectrums are being used but i really don't wanna talk down on your hard work to get all these values. Thank you very much

I have a 3x3 flower room. I cannot find the perfect light for that size. I don’t want high readings just in the dead center I want an equal high level in the whole area.

[@71160000]

Good info but for many of us efficiency isn't the main consideration. I have two viparspectra 600 watt led's in a small grow tent. The light output is more than enough for excellent growing and the heat output is almost non existent. The cost is around $200 each. Unlike the high pressure lamps almost silent. What I'm trying to point out is that many of us compare cost, wavelengths and intensity, heat output, longevity, size, noise, coverage area and penetration, and then buy what fits our needs. As a long time marine aquarist I've long given up on high pressure lamps even though they give an intense usable light the drawbacks are too many for me. Heat, noise, and most importantly having to replace expensive lamps every six months as the wavelengths change with use. Same goes for high output florescent s, too much heat and constantly having to replace lamps and occasionally ballasts making the cost higher to operate long term. For me it's buy more led's than I need and allow them to operate hopefully for years at only the cost of operation.

[@RandomEvents_]

theres a reason most commercial growers use metal halide for vegetative growth and hps for flower. some set up some rooms to test LED but the best bud in the world is always grown with HID. the money i spent on electricity is roughly the amount of money i would spent on a ficture and LED lights break down more than HID and HID are easier to fix or replace. you can get a combo 600w ballast,reflector,timer and pulleys for $189 and you can easily grow 1lbs and $240 for a 4 month grow if your going from seed. can you show me a LED that can produce the weight and quality for the price?

I don't think anyone here can explain the difference in efficiency between a 1.25 light and 1.50 . Does that mean $.10 more a hour for electricity ?

I guess you haven't heard of Ceramic Metal Halide? I work at a hydroponics store. CMH's produce the most perfect match to the sun's light. They use half the watts of HPS and half the heat. The light is white. So, no security problems like the purple LED's. They can be used in veg and flower. They were private until about a year ago. Now everyone can buy them. A 315W CMH runs $380-450 by Hydrofarm. They are cheaper than 300W KIND LED's, $825. KIND has the best LED's on the market, by far. Off brands of LED's are cheaper, around $180. I have two CMH's in a 6'x4' area and they perform great! Always remember you get what you pay for. I would buy something cheap if you are just getting started and after a while go buy a CMH if you want to grow like the big boys.

Hi. CMH is on the list . Kind are low efficiency grow lights with a high price tag.

Wow I'm gobsmacked I've just bought 2x300 watt Miezhie leds only growing 2 to 3 but after watching your really informative video is it worth bothering. All I'm trying to do is get a better product than I'm getting at the moment here in the UK quality isn't there priority. Any help would be great thanks Alan.

I think they are about 130w consumed each and about 1 PPFD per watt efficiency. 260w total x 1 = 300ppfd total. That will cover about 70cm x 70cm for flowering. Should be enough for three plants. They're not very efficient but will work well
