No point in kicking a dead horse. Pity, id like to see Mammoth but i guess the light was never the the main actor in this show. Ego and butthurtfullness is the sign of these times. No matter what it feels like this 720 light should be avoided from the number it seems to have done on OP and i dont think hed go thru all of this if indeed the light wasnt worse than the other version he had. I suppose this indicative of where those GC lights come from (china with no control over what bin or diode goes in).
As for the 'boost' mode, its probably just away to disconnect a resistive dimmer with meanwell drivers so the drivers give that extra 9 % or so that you get with full throttle. Pity, OP could have done it himself if he had the chops. Oh well...

Isn't Mammoth some crap old brand rebranded to try and not suck or am I thinking about someone else?

If so, I think the dude that started this thread is Mammoth
From what I know, they are out of the Albany, NY area and new. No idea though if they had a history. I have a friend whose done a few grows with them and likes them, is buying more for a few more spaces. I'm not sold on them so I went a different route, but hes been very happy with them.

I like when companies offer this info.
Although they all often leave out light Temps on the fixtures. Honest Ir gun readings.
Also, can we trust #'s not 3rd party tested? I'd say sometimes, if it all makes sense to someone who knows how to make sense of it. An Experienced led user or builder.
I doubt companies such as Mammoth or even ROI use false components as to what they state. Alibaba , YES, could & usually does happen.
As for Mammoth there are things to take into account. If they offer a 2000+ umol light, is it designed for a 4x4? Because I would not want that much light in a tent. Ok if going Hi-Bay or spreading the bars. ChilLed has the same issue with their 800w+ bar light. W/o the option of detachable bars or sets of then what good is anything past 1700umol of bars in a 4x4?
I feel this way because I own a 880w x8 Bar Fixture myself. 1780 umols I think using some colors & outside the typically measured par range.
Luckily it was fully versatile & allowed me to detach each set of two bars, slide these bars to be 8 or 9" on center (forgot), instead of the 6" on center they would have been if I assembled all together as in photo. If I tried to use my 880w bar-light in a 4x4 it would be way to much unless it was used like a DE replacement w/ Cross lighting.
Now my fixture covers a 7x5 with nice #'s of 600+ (edges) 780+ (in the field), going up to 1000 after stretch.
Depending on your room or tent this light may or may not be worth the extra output to you.

The Samsung lm301b diode is much used in alot of boards, (esp. the 3500k - 3000k ones) and doesn't need any testing... it's also not deliberately manufactured for horticulture, but common lighting, so that's why I guess some LED manufacturers take these over the lm301h (the same spectrum, but adapted to last longer in a turbulent potentially high rH environment) which may be a tad more expensive to buy.
An amendment with 660nm monos is most likely done to increase the raw umol-numbers, but this step actually would call in for an addition with UV or blue spectrum diodes. And how much Far-Red does this have anyway?

Advice to new members, ignore the Trolls or Haglers that have nothing to offer but negativity. They will attempt to bait you into arguments, shit on your posts, name call, break most POS (think thats what they're called) rules, then whine to their favorite Mod about you. That in turn will get you Slo-Mo'd & your thread removed even if its 100 pages of solid info & bud porn this section seriously lacks, some might say. This effects the whole community when a year or years of hardwork & sharing invaluable info. Goes down the toilet. Not even to be viewed.
Its a shame what the Trolls get away with. I best not speak further.
Goodluck to all trying to learn.

Hey bro! If you ever need a shoulder to cry on I gotchu.
yep, i got more points than you, in less than half the number of posts. quality over quantity

tbh a 100 pages long-lasting thread is perhaps a bit too long and time-consuming for most (I suspect), although it's still of value alone from the documentation inside it.
Better would be to summarize the results of these discussions so newcomers can have a swift overview over the current state of affairs.
And not all of the wisdom was lost, as it's still contained in the minds of the folks which were part of these discussions, actually. Alone the development of these insights, or skill, both in theory and practice, from seasoned growers, can have an impact on the future emergence of new threads and discussions.
Because, you see, the evolution of LED or horticultural tech isn't at its end - it's still emerging and in constant flux. And while we may not have the adequate tools at our disposal, like the big world market leaders in their light laboratories, each and everyone of us can still contribute to this development with, what you've hitherto dubbed "field research".
Because these labs use a number of different plant species for testing, but we're quite cannabis-specific, and hemp is a versatile plant that can be grown in alot of different styles, and Bugbee experiences with it (for NASA) because of the multifold great potential this plant offers (from many points of view, not only drug-specific).
And an experienced grower can easily tell the different of a wellgrown cola or a goofed up architecture. So we don't even need 100% true SBS comparisons, although to think a bit in advance about ones setup, or having measuring instruments, is surely no error.
Alot of what the industry produces is in reaction to what customers buy - and for now, it's the diodes or boards with the highest umol raw numbers. But why, if LED blasts out twice PAR umol than HPS, isn't yield twiced accodringly as well. Where is the lm301b grower that delivers 3g/w routinely?
Samsung claims the lm301h-ONE diode has been delevoped after empirical horticultural tests & studies. However, this diode is very rarely used as its umol-output is less than the standard lm301b/h one. But what if reports would come trickleing in that this diode would net more yield in indoor hemp SBS grows? So what I'm saying is we need more tolerance & courage to dive into new territory in order to proof that certain claims by the industry also hold true for cannabis-specific grow ops. So don't let your hopes hang low - better to return with a vengeance!
There are many interesting specced boards out there... more and more the generic wimpy blue n red basic spec is being amended by "expensive" wavelengths...
PS: and just wait and see what is going to hail from Australia soon...

I agree! And thank you! That was uplifting to hear. There will be umol sacrifices to develop the better spectrum for now. As you said though. Will a better spectrum equal or supercede a more electrically efficient one? More n more growers are becoming interested in the morphological facts, not just the raw output of a lamp.tbh a 100 pages long-lasting thread is perhaps a bit too long and time-consuming for most (I suspect), although it's still of value alone from the documentation inside it.

I aim to show the differences in several SBS's. This next grow is literally x6, SBS At once. One will be contained by a divider while the others will be open field. Have Good idea of the differences already but gives the community an opportunity to see for themselves.
Yes, I've been studying available led chip spectrums for the past year. They're is quite a selection rn.
