Hansion.Abot which supplier are we talking here exactly?
Hansion (HLG), RT2 (PhotonFantom) or Mufue ?
Thanks for the thoughtful answers to my questions. Crazy how this panned out. It played on my personality perfectly. I'm pretty good at noticing bullshit but I got caught thinking I could just skip a step and get boards from the manufacturer. My love of a good deal and the fact I tend to trust people colored my bullshit detector. In the end I'll still have a decent light with good efficiency (I was planning on running it low anyway). In spite of all that's happened I do think I'm going to take a shot that the next ones he sends me, at a reduced cost, will be the C version. Can't shake "gotta get a deal" part of my personality.For sure still better than HPS. The difference could be between 5-25lm/w less depending on the used binnings. But you can compensate it by a certain margin if you drive them a bit lower.
If you buy more boards, then only on the condition that he gives you a replacement for the fake boards or reimburses you a large part of the cost. He knows exactly what he did and the excuse is always the same, someone else is blame.
The bad part is that they get away with it 99 times and only one in a hundred realizes that he was cheated.
Using any supplemental extra red or UV ?yes i'm flowering under all 80CRI 4000k and am very happy with my results so far... big dense ass nugs and frosty too! had very little stretch during flip so that could be good or bad depending on preference i guess. maybe the results would be a little better with different diodes but i'm not complaining.
Plus the advantage in USA now of the new 21% corp. tax rate effective in new year if all gets approved !!!!I'm pretty sure the guys from HLG got a nice price, probably less than $ 35. But they have not relocated production to the USA for nothing.
Checkout ledgardner he is doing a comparison grow at 80 crib and 90 criDo any diodes produce 90CRI?
Is there a noticeable difference between 80cri and 90cri, in terms of yield or bud density?
Link?Checkout ledgardner he is doing a comparison grow at 80 crib and 90 cri

For the sake of comparison, here is a pictureI just took of the diode from a Photon Fantom sunboard. Can we assume that they are authentic lm561c Samsung LEDs? I think we probably should. They look like the ones I have. So I'm not sure what the whole "dot" thing means for the real/fake debate.

what is your conclusion of this diode then? LM561B? C? Epistar?
Hey Guys If You Have Any Questions About My Grow Please Feel Free To Ask
No he is doing them with qbs just look up ledgardner on YouTube the name of the video is stuff on the goWith strips? Link please!
LOL, for sure. Jeezuz, some of these kids need to wait for their other testicle to drop before complaining that someone laughed when they dropped their ice cream cone. @Randomblame is among the most knowledgeable, helpful and non-asshole members of the forum. Attacking him for an LOL, is, well, petty and foolish.Yeah, I should strap him to a chair and force him to read my entire post history, LOL!
That's at their rated test currents according to the data sheets.at what currents, though?
why can't i private message you. gold wires would be visble on LM561C? i just looked at my quantum boards and they are visibly different. no noticeable black dotThat remains a mystery, LM561C looks different in any case. Not only the dot is different, there are also no visible gold wires and the rectangle is also slightly different.
When they refer to the copper amount, they are referring to the thickness of the copper layers - half ounce is considered lowest quality, one ounce is "standard" and the best quality is 2 ounce. I used to work for a company that made their own pc boards. Around 2004 they outsourced the raw board manufacturing to China, going with a state owned company called "China Circuits". About 6 months in, they started having quality issues and decided to cut some raw boards open and verify the trace thickness. They found out that they had been receiving boards with half ounce copper when one ounce copper was originally specified.On another note. In many of the LED discussions I hear (at least I think I do) discussion about the quality or amount of copper (are they traces) being an indicator of quality. I'll attached a picture to show how the copper extends pretty close to the edge of the board. you can see a circle of copper and it wraps tight to the screw hole and down the edge of the board. That mean anything. Give any indication to build quality?

Another excellent example that quality checks are needed if you work with this guys. Also if you get 10 times what you ordered, that means not that the 11th delivery will be the same.When they refer to the copper amount, they are referring to the thickness of the copper layers - half ounce is considered lowest quality, one ounce is "standard" and the best quality is 2 ounce.

And this was a 2 billion dollar a year corporation I was working for, not a small company.Another excellent example that quality checks are needed if you work with this guys. Also if you get 10 times what you ordered, that means not that the 11th delivery will be the same.
So Jeff is willing to stake his reputation and sell some boards that don't have LM561c? Just because the buyer is only committing to a couple of boards? Sounds like conjecture to me.you have no facts. that is called conjecture. You do NOT know you are making up to argue and you call me a dumbass while you make up information to argue with. name a fact you provided so far beyond retail price. you have no clue to wholesale production, i.e. conjecture.
I have facts.I work with Jeff regularly as my regular supplier. we talk all the time that is how that works, business relationships.
I get real boards with real Samsung diodes that work great too.. facts.
I am not here to argue, just point out the differences. If you have facts about HLG and their production costs, I would love to hear more, as they have NDA's.
I do me not worried about HLG.
makes life simple.
