New Migro Lights?

[420AD]

MIGRO ARAY 750

The MIGRO ARAY 750 is the most efficient LED grow light for 5ft x 5ft or 1.5m x 1.5m grow spaces. Delivers high PAR intensity uniformly & controller compatible

Saw they have a new series of lights.

I'm pretty shocked how good these look on paper.
Way to go Shane!

Agree 100%.

The 150 is the new King of the Hill for the 2' market and I can make the argument to use 2 of them in a 2' x 4', as well.

I got two coming Monday or Tuesday. Couldn't beat it for $600 per unit.

If my lights fail me I would surely consider it, despite me lot liking the bar style, as mentioned you can't beat the pricetag with anything near as good.

"bar style" - meaning front to back rather than side to side?

That 750's really sweet. What light are you using now?



I did a "Contact Us":
"Are PPFD maps for the Aray 150 at 12" and 14" hang heights available?"

and got this reply:

"we only have PAR maps available at 16", 12" hanging height is too low for even light spread."

The PPFD map at 16" for the 150 is really even but I was hoping to get a little more by dropping the light. No a major issue—1000 to 900 is the same in real world terms. My most recent had some spots >1100 and I ended up with fox tails so 1k should do fine.

Yeah what I actually meant was the big fixtures, I completely disregarded the fact that there's smaller fixtures with the bar style out there too now, my bad.

So basically I don't wanna have to take out all the plants to be able to raise or lower my lights, so I have 2 smaller lights rather one big light.
Not sure if heatwise it wouldn't be better to switch, and also the efficiency is so good now that I would actually also make sense.

Still gonna wait ...

I have no problem raising or lowering my light with plants under them so long as I have a 2nd set of hands.

My apologies, I just found your response.

I completely understand using multiple lights!

From my most recent grow. The main light is a Growcraft X3 with a pair of Vipar GlowR80's in between the light bars.





There are a lot of lights in there but they're not running at 100%. The Mars SP3000 is only at 70 watts or so because I'm using it for the "front row" on Donna. Erica has a Vipar XS 1500 that's running at about 75%. The hang height is low enough to get 1kµmol± on her canopy.


In all seriousness, though, if I was growing in ambient CO2 in a 4' tent, it would be two Spider G4500's with a pair of R80's. No question about it. One great thing about multiple lights is that you can raise/lower the lights separately because 16 square feet of canopy will not be flat.

And there's also the redundancy factor so you still have one light when one of the two fails.

And it's easier to move a smaller light than a big light ended for a 4' x 4' space.

Not that I have an opinion on that.

So i never wanted to post my doubts about the specs on this light; 3.2 wall efficiency doesnt seem right or possible with that diode count and the posted spectrum (looking like 3500k base white meaning some really heavy lifting being done by 660nm reds). Now gml seems to have done some tests which throw some shade on the array.

I think this only shows the downfalls of just looking for highest claimed efficiency for the least $$.

I’m not the biggest GML fan, he dodged some simple questions I had for him on Instagram, but I’m not the biggest Migro fan either. It sucks that it takes one light maker to call another out, but it’s also cool to see people get caught selling or saying BS. Good on GML for keeping things honest, even if they dodge questions themselves

Yeah, there seems to be internet flame wars around him most of the time. what was the questions he dodged about?

Ouch.

Hard to argue with the results in the GML video. And the last segment of that video is just brutal.

i still think the migro light looks quite decent, 2,9ish, and at least we now have metrics on it now. But it depends on if people wanna deal with Migro anymore; if theres been deceptive marketing re spec then will warranty be good for full duration?

The story; there was this Agronomist on IG who goes by the name SlowNickel, who had just started talking about light spectrums (which is well outside of his lane of knowledge). This was a few years ago. He was talking about the benefits of Far Red and blah blah blah, basically citing a Bugbee study, which I have plenty of issues with myself, but then GML chimed in and basically said “growers who don’t have Far Red added in their spectrum are missing out on a lot, leaving a lot on the table and that adding Far Red was a Game Changer” or something basically along those lines. Having grown with supplemental FR myself prior to this, I knew the claim was overstated if not outright ridiculous. I simply asked what changes one could expect from the addition of Far Red to a full spectrum? Like what morphology differences, metabolism differences or chemical profile differences one could expect? Nothing. It was a super popping post too, and he was responding to other people. Then I went to GML’s page and asked again on a different post. Nothing.

Granted, I was trying to catch him in “gotcha” moment, because people making absolution claims is something that irks me, and I’ve been known to ruffle some feathers. But it was a super simple and basic question that I knew he couldn’t answer honestly.

Anybody selling anything that won’t be intellectually honest or transparent is a big red flag for me.

Yeah that type of shit can be a bit triggering to me aswell but so can those gotcha moments, lol.
My far red experience is at best lackluster but i think that theres likely better solutions nowadays: osram osconiq 3737 comes in 680nm at extremely high efficiency and 680 is able to excite both photosystem 1 and 2 so should be able to do away with both 660 and 730. Unless theres another thing to 730nm.
680 also seemed to bring some bud quality improvement for me but granted its very limited and subjective.

I totally get that, lol . I usually only call people out when they have been disrespectful, unpleasant or are spouting some BS. Otherwise I usually try to keep the peace. Also, people who make calls to authority because of XYZ reasons. Like light manufacturers who think they know more than everyone else because they make lights

Ive been wanted to supplement 680, 700 & 730nm diodes in addition to the white +660nm for awhile now, but I’ve got too many things going on to play around with them now. I think 660nm can still be beneficial, just maybe not in as high of a proportion that we typically see from modern LED grow lights (huge 660 spike). LHC II still has a high absorption rate at 660nm, as well as phytochrome.

Unless theres another thing to 730nm.

This is a theory that I haven’t yet been able to test, but I personally believe that any benefits of Far Red wavelengths will not be fully realized without supplementing some blue/uv spectrum wavelengths to fully stimulate the phytochrome system.

First, gml has another vid up, 2 parter drama, lol.

This discussion is maybe not really for this thread but you can see how 680 will excite both Pr and Pfr that togehter with just another little bit of reds you could probably leave out far reds.

You’re right. Something to consider, food for thought.

I wouldn't worry about the warranty not being…"honored" <= no irony in that word being used, eh?

Unless I'm mistaken, you've also mentioned at there's synergy when 640 is used with 660, haven't you?

If that's the case and if there's a demonstrable cost/benefit ratio, we should start seeing those improvements in the next few years. OTOH, if it's subjective, that could be a tough sell for an engineering-focused company.

As we see in the PC market, innovation is expensive and these are commodity devices.
