>no they didn't..you are mixed up.

..have you ever tried 561 b's ?

ordering from china is much cheaper especially if you do you home work..like half the cost and except for some

connectors that got smashed in shipping the panels have been bullet proof

please try harder to attempt to convince people by saying you have an open mind

.DYOD.. know what it means..?

bye

I'm not sure if you have comprehension issues or you're just deliberately trying to be obtuse, but Post #15 seems pretty straight-forward to me - and I assume most others who can read English.

You didn't seem to understand my first post very well either - you twice referred to a company I "mentioned", though there is no such mention.

You also took to task Post #3 for a simple typo most of us here realised as soon as it was posted.

Are you here for a strawman argument, or are you really having trouble following this discussion?

I honestly don't care how LM561B LEDs perform - your point is moot.

If I'm paying for "LM561C S6 boards" - such as the ones labelled below - I expect to receive "LM561C S6 boards". This was one of eight boards labelled as such. It was no mistake - it was a deliberate ploy.

Likewise, I don't care if Chinese boards are half the price of others if I'm still not even getting what I pay for.

Again, your point?

For some reason unfathomable to me, some customers of the Alibaba vendors take quite personally any suspicion or incredulity regarding the veracity of these companies' claims. I happen to think disclosure is a plus, and is something that everyone should support. But I guess that makes me an asshole?

not for me

i call it.."i bought panels..at 50% less than it would have cost me if i bought them from the same people who got most of their

panels made in china..but now apparently usa..

..i have been using custom made china leds for a good 3 yrs and they all still work good"

..even the 561 b i accidentally ordered

next order i asked for 561c s6..they sent me the 561 c s6 bags the diodes came in.

[yes of course they bought the bags on ebay so they could bilk me..]

......sigh..lol

I ordered from rita at meiju too and satisfy with what I received are they lm561c s6? Maybe maybe not but they grow good and are more efficient than hps either way.. pulled 20oz of quality buds plus couple oz of larf with 520w so im happy with the result - could have been better as I had some issue with my soil.. on my second run now but everything is looking good again here is some pic for the doubters out there.

Connectors are weak on the board but if you dont move them you wont have an issue and if ever you have a problem that a connector fall off than there is another set of connector on the other side of the board.. that would be my only concern.. it has been documented over and over again.. very low failure rate if any from china boards and if you get more and run them lower the efficiency is increased which compensate for potential lower bin.. there is a full thread on knockoff as well with pages of comments and result and testing thanks again a lot to @Moflow for a lot of the testing!

i know you are joking because way back when the led forum was newer i DYOD was used all the time..

now we just start threads and expect everyone to fill in the blanks...

Wasn't joking. Thought maybe you meant "do your own digging", but wasn't sure. In any case, I don't see why someone should get shit for asking the people who've already "DTOD". That's one of the principal functions of community.

I don't think anyone is doubting that they'll grow well. It's more about whether or not peeps are getting what's advertised; I'm sure some are, but I'm also sure some aren't. @Prawn Connery is simply trying to establish which companies have a history of lying, and which have a reputation for honesty.

Looking great in your tent!

There is very few amongst us who have the tools neededto test the boards and even then some boards could be legit and some other not as I know it happened to a few people..quality control is also very poor in china so there is no way to know if every order of the same product will deliver the same results.. there is no such thing as integrity when dealing with china but the return is youll pay 50% off retail and whatever you get.. some prefer the piece of mind and top end product then go with NA company that test their product and back with guarantees.. but youll pay the premium if you decide to do so..

Its pretty much like any extended warranty that you can buy on your electronic gear in store.. you may always buy it and never use it as you may never take it and need it down the road.. i just think the led on a pcb board is such a simple product mainly machine made so risk of error is very low and keep in mind led diodes is probably not more than 25% of the total cost price.. the pcb board itself taking most of the cost so there is clearly not a big benefits for china to use cheaper diodes if the “real” one dont cost much more (fraction of cents per diodes probably at most)..

There can certainly be a big difference in wholesale prices between obsolete diodes that no-one wants and current, top-bin diodes that are in high demand - as much as 5c per diode or more. Add it up, and realise that US$1 is going to go a lot further in China than it is in the US, and you start to understand why saving $5 here, $10 there is very much worthwhile for them on a $30-$50 board. You need to know how China works to really understand why they do what they do.

I'm glad someone here gets this thread. I didn't think it would be that hard to understand the raison d'etre. < I hope that term is not as obscure as Dig You Own Dirt or Do Your Own Dishes or Dunk Your Own Donuts or whatever it was.

Seems like the thread is getting further away from actual experiences of buying china.

Has anyone got anymore companies to mention? R2THK comes to mind, i think @Moflow used them.

Anyone had a good experience buying monos or drivers from china? Or bad?
