PPF/W is determined by a few different variables, mainly by current. The error in @EfficientWatt 's argument/point is that he left out the fact that my fixtures possess a dimmer knob, so my PPF/W for my fixtures can be attuned to various levels and aren't just limited to 1.82 PPF/W and can actually go upwards to 3.4 PPF/W if fixtures are dimmed down a spell.

And with enhancements such as the sticker below, hitting specific PPF/W values can be easily obtained with my products.

poppycock

PPF/W is a basic indicator of efficiency. Yes there are lots of variables in calculating PPF, but if its still a basic indicator of efficiency and its apparent that you don't care about efficiency.

In the mini mo that I saw you are running two cxb3590 at ~2.36a each, for better efficiency you would run them at 1.75 or 1.4 which most of us do. That alone makes your light pricier on a photon basis compared to tasty, plc and most DIYs.

Additionally you are running them in parallel, which means if one of the cobs inadvertently fails the second cob will be fried when it gets the whole 5.72 amps.

Did you even bother to measure the actual PPF in a sphere ? Your published numbers don't appear to match.

To Aquarius his defence, his fixture is dimmeable 10-100%
So you have all the options amperage between 10% and full power.

If you want to run the light at 1.75A or 1.4A you can run the minimo at those amperages, it's up to you since it has a dimmer

Also Heavenbright is not worse than Tastyled.

The T-2 2100 is 360 dollar (Tastyled)
2 36V cobs at 2.1A (152 watt)

Minimo is 375 dollar and uses the 72V 3590s at 1.7A* (270 wall draw, lets say 250w without driver losses, 125W per cob 72V) with the option to dim.
If you dim the Minimo to 1.05A you will have the exact same light as the one from Tastyled. Equal in output and in efficiency.
If you need more light output you can throttle up with the Minimo, can you say the same about Tastyled?

The difference between Tastyled and Heavenbright is that the Minimo has the option to dim and has up to 70% more output and costs 15 dollars more. (which is a minimal difference)

@PurpleBuz

You love using that word Poppycock, don't you? Lol.

Is efficiency derived without taking into account current? So we're both right about that part, which is why I said there are multiple variables that dictate the value of PPF/W, including efficiency.

I care about a lot of things actually, including efficiency, which is why I included dimmers for my products rather than opt to configure my lights to be set at fixed outputs. In other words, I care more about what my given customer can do rather than limit their options by trying to stand behind a silly belief that efficiency is the holy grail behind mother nature herself. Simply, I let the user decide if they want to run at full power, which is actually 2.86A per cob with the Mini Mo', or if they want to take it easy and run, say 402mA per COB. The thing is, every grower is different and assuming that everyone has the same needs is an ignorant stance to take.

As for your parallel comment, that is correct, I've been successfully running cobs in parallel for almost a year now. I was hesitant at first about implementing such a practice because the choir here only preached running in series but after discussing the matter to Mean Well, you know, a legitimate organization, I was assured that it works well in the applications that I implement, so don't go start fear-mongering something you know little of in pursuit of tarnishing my name and brand.

I don't see the purpose of running a test in a sphere, mainly because total PPF doesn't tell us everything we want to know about the given light that we're using but instead only total PPF output. PPF calculations are a good factor for comparison purposes but if all your PPF is going in directions that are undesirable, say to the ceiling, then how can you take the light seriously? Or what if all the PPF is from a mono led, say 660nm red? Instead, I think having a single cob, say the Vero 29, tested in a Sphere, followed by testing a CXB3590 would lead to more a worthy understanding of the lights that most of us here use for our own purposes.

I understand the benefits of a dimmer, and many of us use dimmers.

BUT running a light at 50% to get a reasonable efficiency doesn't make sense. You aren't making a fair comparison, since any of the other lights if dimmed 50% would be even more efficient.

what I said is fact. no fear mongering here, if one cob fails for whatever reason, both will fail. do you even know what the max current the cxb3590 is rated for ?

Its a lie if you are publishing a PPF number without measuring it. Estimations and projections do not count. You have to measure it to publish it.
The usefulness is that many light systems publish a sphere measured ppf value in their specs which allows comparison to other lamps.

How did AP dim there lights? It is real dimming or only PWM? If PWM the efficience will not raise at lower Amps.

Well not everyone in the world gets along, so I understand your stance.

Call it passive fear mongering if you may. I use 36V CXB3590 cobs, I've ran them and CXB3070 cobs at 2.86A before, no problems when properly cooled. The max current for 36V CXB3590 cobs takes place after 3.6A, with the Vero 29 max current taking place around 4.2A. It's worth mentioning the StarDustSailor tested the limits and stability of the Vero 29 and made remarks that it could withstand currents above 5A, as he had tested them. I think he was like pushing 7A or something on a single Vero 29, lol.

As for PPF, who says you get to make the rules? Can you make a list of light systems that have been tested in a sphere and can you accompany your list with proper documentation that each sphere testing company did indeed test the lights?

@BenSeiDank

I utilize potentiometers on my products, not PWM.

its the meanwell a version 3 in 1 dimmer, which is a real dimmer (internal)

so you installed cxb3590 and yet you reference a vero29 ? stop talking sideways, do you really expect a cxb3590 to run safely at 5.2 a with that tiny heatsink ?

That's why I cannot recommend your lights to anyone. your not publishing usefull data that's accurate. That makes you no better than the cheap chinese blue\red led marketing.

Typically with driver selection, I choose version B drivers from MeanWell, as then lights can be dimmed by an external knob. In the case of one of the lights that was sold to Hanzo, it was equipped with a version A driver, as it was during the Chinese New Year and no vendors had the version B driver, so I told him that once the new shipments start arriving and his harvest comes into play, that we'd make the switch.

Anyone seen the new Heavenbright DIY Led trailer?

I offer all my customers the choice of Vero 29 and CXB3590 cobs and not just one series. Who said anything about a CXB3590 running at 5.2A? Again, if MeanWell approves of my applications of running cobs in parallel, then I don't really see the need to fear monger or worry about worse case scenarios; I offer 5 year warranties on all my products. Guess what, anything could happen and you're just pinpointing one speck of my product and trying to dismiss my brand in order to feel better about yourself and your beliefs. Guess what, despite you and your cronies efforts, I'm still gonna be here in the end, and I'm still gonna sell lights and one day I'm going to be at the top of this game laughing at you and the others for all the shit you've tried putting me through.

that's what happens if one of the cob inadvertently fails, the other cob takes the whole load ....

come on man. its great that you have warranties and all, but that is a basic weakness of your light.

Is the foot print a good size on that 6 chip lamp?

@PurpleBuz

Yeah, that's what they say, haven't seen it happen though with these cobs. Guess what, the chances of a cob inadvertently failing has the same likelihood of a given fan failing. So should we all fear about the unlikelihood of a fan burning out and instead run all our cobs passively?

@a mongo frog

I think it is, everyone has their opinions you know

Actually I saw a case of parallel failure on RIU. It was a classic case of thermal runaway, when one of the parallel legs failed.

Well Tastyled can cool passively, so I don't even have to worry about my fan failing ever. Just another reason I do love my tastyled lol

But holy crap there's a lot of anger in this thread. You guys should go smoke a bowl and chill

Also, I think the main selling point on LEDs is that they're power efficient, and I think that efficiency is most apparent at lower amps, right? I'm no LED expert so what I'm saying might just be bullshit, but if I was going to run at 2amps, wouldnt that kind of ruin the power efficiency? Shouldn't I just buy an HPS or something at that point?

sorry if it appears to be anger, not meant to be just facts.
