Why would you just grab 1? I bet you they will be out of stock before you get the test results back and the test will cost more than the light by far

Ya, they are reasonably priced (HLG304), but I want to know what chip I have. It's not about money at this point, I want definitive chip identification. I want to buy a board to replace one of the ones currently being used, so I won't be having to wait to get results back before I can order them.
They also don't sell the 660nm mixed 304 so HLG wasn't ever an option when I was purchasing for this style of QB.
I think many would be curious to know if a visible ESD is definitive of s6 or not. That's valuable info. Also if they do test s6, that's also valuable info.
And still for only a 5-7% difference between s5 and s6, its a $140 difference between HLG s6 w no 660nm board and Chinese s5 w 660nm board (and that's at clearance sale of depreciating tech)..
If you haven't read all the dialogue then I can understand your confusion but at this point, I want to know without a doubt, with proof that nobody can argue wtf I was shipped.
You are thinking too much just grow some pot im not sure what your point with all this is just some OCD? How about you just buy Samsung strips or the QB v2 that is made by Samsung. all that matters to you is getting an authentic product but you refuse to buy from reputable companies if the 660nm means that much to you get supplement strips

Man stfu you dont gotta respond if it's not for you. It's not your money and not your experience.
It's about being lied to. About making me go through all the steps to prove what we all knew to be true. Now I'm just jumping through the hoops to get what is merited. Why you got such a hard-on for not testing and providing data? If you're ok with getting ripped off and think that it's not normal to want to pursue a refund in such a scenario then we're just different. But again, why the fuck wouldn't you want to know? Especially if not on your dime? Doesn't make sense. Are you afraid they might be s6 and then would be upset you overpaid for your name brands? I seriously can't think of a scenario why you'd care? Especially if you run LM301B all name brand? What's your dog in this fight, why you leaning against me getting them tested, and knowing definitively, and objectively? I'm providing data on what to expect from this company and also some more data on the visible/non-visible ESD debate.. You got a thing for Rita or what? Lol did you accidentally save this thread as your homepage???

“It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that's all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot - it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.”

now man up and eat your losses instead of still bitching around. you got played. accept it.

Lol if I get it tested I have them by the balls! Me getting 10x my refund back or any sort of negotiating is contingent upon it! Since when do you read a business passage and accept getting ripped off as you lazily doze off to bed? Lol "welp that crafty salesman got me again today phyllis," lmao I cancelled the order and waited 4 days for confirmation they were s6 before giving the final ok to ship and place the order, I did my due diligence. I made them state they were s6 and told them they would be tested when I got them. They knew what they were getting into. I don't see why you and ryantee give a shit?

I love how you make it out to be me not spending enough money though lol...

Great quote lol being greedy about your money is probably a trait most successful businessmen have...

for me its easy, if i buy from digikey i only pay german added value tax on the price that is shown on their website. all duty and shipping costs are included. arrives here from the us in less than 2 days. stuff i buy from china that has shipping included takes weeks till it arrives here and it's a gamble each time if it goes through customs unnoticed or if i need to pick it up at the customs office. if i want it fast i need to pay DHL for doing the customs for me + paying for shipping extra. add to that the possibility of getting ripped off and the choice where i buy is quite easy...

How are you going to prove anything when you have a mix of LEDs, including 660nm, that are going to throw off the total reading? Or are you going to remove a couple of LM561 LEDs and test them individually?

Took 3 days to get to me, can't help tariffs, and they used DHL, as well as me signing up with trade assurance to further "garuntee" my purchase. Just because it comes from China doesn't mean its low quality. Iphones are made there, for example, along with practically everything electronic. You're missing the point.

Whatever tests need to be done to tell conclusively the identity of the LM561C chips I got. I'm not debating I got 660nm epistars. So, yes ideally I'd assume they'd pop off a random sampling and if they all tested the same flux bin then they'd know they weren't mixed s5/s6, also then what flux bin they were and whether or not I have claim to any money and what chips the "rip-off" Chinese boards come with when they tell you s6. As well as try to assess whether a visible ESD is definitive of anything.
Idk how they test things like that. Idk if they have a big enough sphere to do a whole QB? Then maybe they could cut the epistar out and wire the 561 back in series? Just test one cut portion? Random single tests? Idk..
I'd anticipated it being destroyed to find out. That's ok I just want to know because I'm sick of theories or conjectures without any real data. I guess its just a hobby and when you get into a hobby you pay money for things that others might think are ridiculous. I thought there were more hobbyists that would share this sentiment in finding out definitively what they were but not really I guess. I also thought testing flux of visible ESD vs non visible ESD would interest fellow hobbyists too, but I guess not lol

yes. but you buy the iphone by apple, you don't shop around different chineses manufacturers to get the cheapest iphone. and i buy samsung strips by samsung, not the cheapest samsung strips that are available...

To me that amounts to as much as I shop at Wal-Mart and you shop at Whole Foods. Thanks for your insight.

I don't see what's wrong with price comparison? If you search for the highest prices, then more power to you (if you're convinced that nullify's scams), Ill continue to let price influence my decision, especially when they claim money back if they are not identical items and after I tell them I will be testing them.
Scenario:
Buy 304 boards without 660nm for [($47 + $39 for heat sink + shipping) + (~$40 for 660nm)] × (θ).
~$126 × θ
Buy 304 boards with 660nm for [($50 heatsink and shipping)] × (θ)
~$50 × θ
They are C chips, so it's the difference between s5 and s6, or what people have stated as a 5-7% difference in effeciency.
Ill pay $50 + testing fees on the chance of a total cost of $400 vs $1,000. That's a $600 difference in only 2 tents. Spend $150 to make $450 is 3 ($450) to 1 ($150) on my money, if there's a 1 in 3 chance they are s6 then that bet breaks even.. and an educated risk. Plus s5 is pretty good as well if shit hits the fan and I don't get a refund. So there is only upside minus the cost of the test and initial board, imo.
This scenario was only 2 tents and you can see that the extrinsic value of a test like this grows with the order size. Ie the cost to benefit ratio decreases. Imagine the possible order size is this entire community and you can see the cost to benefit ratio is also very small. That's what we do here, we submit data to make a larger collective so that we can all draw on everyone's efforts instead of just trying to acumulate knowledge by self discovery or solo experiences (not talking about masturbation lol). It's just a piece of the archive.
Is 5-7% effeciency increase worth double the money? Because I'm a hobbyist Ill spend a little extra to find out how big the difference is before I hall off and pull the trigger on a bunch of the name brand..
Is it a waste of money? That will depend on what the test says and if they are bound to honor their word if they come back as s5. Will they still grow plants? Yep. Is it about getting genuine chips for you? No not really, slightly, but more or less the principle of the matter, and the data from the vis/non-vis ESD chip testing as well as definitive proof in what I have.

Its not just about me. Its for anyone and all. Its a thread to help provide data like what's been shared thus far by the helpful participants.
If you have questions about your chips throw em up, maybe they can be identified.
I learned the 561C chips have a larger "inner diode" than b or b+, on here, big thanks to the contributors of that data, and everyone that's helped me.

If you're interested in just selling the boards? I maybe interested. Are you in the states? @ChiefRunningPhist

Not these 4, I'll be using, but if I were to use this model as part of a cheap base beginner build that I sold to buddies starting out in LED, it'd be nice to know definitively what they were. Message me if you wanna chat more about designing a light together, that would be legit.

Next time im buying from Rita i will ask specifically for S4 bin to see what happens. Sphere test them and aall. Lord knows there will be problems if i find out shes stiffing me with S5 bin.

I dont think they make a s4 3500°K. Lol
From S5 to S6 is an upgrade. S6 to S5 would be a downgrade, or an example of a 'S5 stiff' lol
I guess I'm the only guy that cares lol. I know that when I post the results you'll all be watching to see what they are whether you chirp then or not. Don't understand the hate, I got warranted anger in this perpetuated lie or if it isn't a lie, then a great find and worth every penny of drama and all you will benefit from, like I said, where the downside? Unless you're holding out the data on vis/non-vis ESD flux that's also an additional upside.
Everybody drinking that Hater-ade..
