The Chinese Quantum Board Knock Off Builds

The one posted LM301H is that the one that’s not marked as the LM301V now look at the 3000 Kelvin and tell me that the LM301H doesn’t have as high as a blue spike as the other

Where are you getting this data from. Post a link please.

Yea I already went thru this bud a lot of people did just stop while your ahead 301b is 301h period just stop...

Guy is pulling the same spec the guy ain’t that smart just look up the 301 b and h talk from gg explains it all just I’m getting sick of this shit...

Just another Kingbrite/Alibaba experience to throw on the pile:

They took 2-3 days to get my order out, and I had it in my hands about a week later. After some of the horror stories I've heard about getting stuff shipped from China lately, I was very pleasantly surprised, and impressed. Packaging was good. No weird shipping labels with a bunch of Chinese on them, unlike some other things I've ordered direct, and the only indicator of the contents was a very small mention of a "lighting kit."

Build quality seems solid enough. I just got one lower-end 240W light to try out but I have a feeling I'll be going back to Kingbrite next time. No hours on the light yet but I see no problems with it.

How much was the taxes through customs? Sales rep on alibaba said he would mark the price down for tax reasons

i dont know what your looking at but they look the same to me.

but yer this has been gone over many times on here and elsewhere, they are the same diode, even a samsung rep has confirmed this.

and think about if they had changed the phosphour coating to 'shift' the spectrum like you claim you would see a pronounced lowering of the 450nm spike (the graph doesnt show this) and you would see a widening/right shift of the red band (again the graph doesnt show this) otherwise where has the 'shifted' light gone?.

They’re not the same they’re just the same footprint same everything but the H version has a different phosphorus coding which produces a different spectrum more tailored toward the red and the 2700 and 3000 K Calvin just like 4000 5000 Calvin the phosphorus coding on those helps balance everything out to reduce the blue spike and higher Calvin LEDs to prevent plant Stunt and smaller compact from too much blue an increase is more red and the higher Calvin to equal it out I am just the opposite with the lower Calvin it hasSo Ezy basically affecting the blue to red ratio to help promote better growth from plants

Not true. They come off the exact same line from what I know

Please post where you are getting these data sheets from.

There from Samsung.

Sorry man quoted the wrong post.

I think i remember Greengene talking about this in one of his webcasts: its an error in the datasheet. If you actually look and compare youll see that the extra red is the just the same as another spectrum, they were just sloppy at samsung. If you find 2 spectrums that are the same in the data sheet but have different cct numbering then somethings gotta be wrong with the datasheet. I havent checked it myself though but im fairly sure that he had confirmation from samsung.
Also: the 2 diodes being the same is also confirmed from HLG Stephen.
I don't know, ive heard it from so many that i respect their word that im not doubting it.

Where do you have your info from other than the datasheets? Im pretty sure theres a root to this somewhere...

Edit: infact maybe ill have to take that back; those spectrums all look exactly the same, wheres the actual difference?

Actually right I can’t really tell a difference neither I just thought I remembered see Ende somewhere of the compared spectrums that the horticultural version had just a slightly different ratio but they look like the same like you said I can’t tell But truly the only way would be to have a lab test so we could actually see the red to blue ratio but They do have a different phosphorus coating because it can withstand more humidity and the environment of being in a grow tent compared to the LM301B that I do know is a fact

Anyone here use cutter strips? I had a few questions I'd like to run by someone

You’re correct I can’t see a difference neither it just add that I remember reading and seeing that it was but even though the spectrum looks the same they can have a different reds and blue ratio that is possible not saying that that’s what Samsung dead because I’m leaning more towards of what y’all are saying now that they probably are the same see I’m not some person to argue just because that’s what I believe you guys actually showed to me and I listen to yawls debateWe had and yeah I’m with you now I think they probably are just the same Samsung tells people they’re different just to try and get more revenue

if the sprectrum looks the same then its the same, it litterally cant have a different red to blue ratio.
what you can have is two 3000k diodes with different red to blue ratio but both still 3000k, or two of the same 3000k diode but different cri with different red to blue ratio.

 

[Powertech]

Do you veg and flower in that tent?

no just flower, the Archibald I got are 3000k not the mix, but they have that option

 

[DrKiz]

Hey everyone, I got quoted a price of $760 including shipping but with an additional 2.95% credit card fee for the light below. In your opinion is it worth it? This is the style of light I like and don’t want to do much DIY-ing.

Not sure, was I supposed to get a bill from Customs or something? I paid a fairly reasonable shipping charge and nothing else. Under $200 total, if it matters. Is there a threshold value before that comes into play?

Not the genetics we usually discuss here, but is that a Bengal cat? Beautiful markings! I want a spotted cat, and for a while we thought we had to get a bigass crazy savannah cat for that, but I've seen a lot of people talking about bengals lately (and not just Joe Burrow).

Semi on-topic: my cats do not approve of the box Kingbrite sent us from Shenzhen, because it's just thick enough for the light and a little padding, and not big enough to climb into. I thought it was fine though.

Yeah I have 2 bengals
