New style Samsung LM561C Board

I ended up accidentally breaking the hinge off, didnt take much pressure though ... the internals seemed to show to me that it seems a blob of solder is preventing the 'gates' from moving ... even with needlenose plyers they werent moving ... I ordered a soldering iron last week so should be here this week, so maybe hopefully i can 'dab' it to let the wire in.

I'll email Meijui about this problem - apart from this issue i'm happy so far (delivered quick, well packaged, genuine lm561c's, full 'kit' with everything required, solderless DIY, good tech support). I still have the 3000k flower board waiting for hookup also, so I'll test that next

[update] just tried the other board, the exact same problem in the exact same spot :( will await Meijiu email. Their tech support has so far actually been pretty good for the most part
Apart from this issue your happy? Not being able to use the boards is a pretty big issue I wouldn't be very happy.

Those connectors are very specific in the wire it normally accepts as well as the shape of the cut (have a look at the samsung strip datasheets, they have a page in about the connectors.

Thanks everyone, yep they are Molex Lite-Trap connectors
http://www.molex.com/molex/products/family?key=litetrap&channel=products&chanName=family&pageTitle=Introduction
I've read through all the docs, im confident im inserting them correctly and the wires are acceptable, but haven't found any troubleshooting about "What happens if it wont let me push the wire in?". The wires provided seem fine to me and they worked perfectly in all the 3 other connectors, it's just this 1 connector ... and when i tried the other board, again same problem - all the other 3 worked fine, yet the same connector in the same position isn't letting me in, i just keep bending the ends from force. Still waiting to hear back from Meijui, and will contact Molex as well

yep looks like i'll be going the soldering route... still waiting on ebay delivery for that though lol. On a good note though I just found two rings of allen keys in my late father's tool case so i can undo the socket screws to access the underboard, phew - thanks Dad!!!♥ Then i guess just switch one of the four unused ones over with the faulty one and i should be back in business. Direct solder if no luck with the reserve connectors.

Molex tech support reply... not very helpful (prompt though)

Sounds like the solder equiv of slag or drips. Since it's the same position on several, I am guessing the device being used to SS them to the PCB is probably damaged.
 
Nope! That was random!
All LM561c in one spectrum look more or less the same no matter which flux bin it is. You can not differate the flux bins because of slightly differences in the phosphor layer. Also the ESD device looks minimal different from diode to diode but that means not you can differate them because of it.
We can differentiate LM561c from other diodes like LM561b+ but differences within the series are just randomly and do not say anything about voltage or flux bins.
Correct mate and thanks I'm very happy with F-series strips
But who thinks that Chinese alibaba scammers are thinking about the yield of their crops? the goal of these Chinese is to get rich not that you get the best harvest now they will be lm561c of the worst bin and the cheapest, if you see that it is lm561c they are already happy but what are s4? s5? A1? AZ? this can produce up to 20% less efficiency do you really risk losing a 20% efficiency for a few dollars? as I always say I prefer a B+ good bin assured that those C with the worst bin,
it's crazy to see how the Chinese sell here and do spam by placing links to their scams without the administrator taking measures,
I think that @rollitup should take the necessary measures so that these scammers stop cheating the guys from the forum

you may be misinformed.. you wont get s4 so you will get either s5 or s6 or lm561b+ which are all about 10% efficiency difference from the top bin..

A few dollars? It would have cost literally the double to go with hlg vs chinese.. so for the same price I get twice as much light 10-20%(according to you) you will still end up with a better result per dollars spent (20% less efficient at worst but twice the power if you really wanted to for the same price) .. and I mean at the end of the day Its a simple board with leds nothing more complicated so there is not a lot of risk of failure.. anyway I respect everyone decision.. but dont trash talk because you prefer to pay double the price for pretty much the same product

Cost me 400usd(including shipping and customs) for 4 boards 2xheatsink and 2xdrivers and all the necessary wires and connectors..

Same kit from hlg would have been 650+20shipping + at least 80-100$ custom charges so close to 800$ usd.. thats a huge difference

You wanna talk about customer services? The chinese person I spoke to reply to me within minutes when I write to them.. thats fast ans reliable customer service so far.. to each their own.. you want to pay Hlg fine.. I think their idea was great, their setup is great, etc.. but we also have an option to buy for much cheaper with about the same quality so just let it be

The biggest scam is probably the blurple light claiming they are efficient because they are LED when in fact they are probably just as efficient as hps.. so no efficiency gain for switching from hps to blurple

Thats like buying a Honda vs a Porsche an saying they are almost the same. Sure they will both finish the race but there's only 1 winner. There's no reason to buy random Alibaba junk when you can buy the Samsung strips. And since you don't care about efficiency the bridgelux eb are also an option. China crap on alibaba is a scam to many other options to waste time an money on that imo.

If the honda and the porsche finish the 1/4 miles with the same time.. up to you if you want to spend twice the price to get the same benefits aka win the race or in our case bigger yield. Oh yes you get leather seat with the porsbe but at the end of the race.. both car made the same time.. yes here and there some people got bad batch of lights from alibaba.. but like everything else they get better to a point today thats its not worth (to me) to spend twice as much for the same end result..

You don't drive much do you? Haha I guess what I'm getting at is you didn't save money you could have gone with the strips and had more output for the same or less money. 10 percent less light is 10 percent less bud. I'll keep my extra 1.5 oz per lb that will pay for the couple hundred more I spent on lights. But you do need grower skill to realize the benefits of that 10% so I can see why it might not matter if you get good enough at growing it will matter.

I dont drive honda or porsche but do have a camaro and I love it..

Yes i could have used strip but then I bother with a full diy which i dont have the knowleadge and im not confortable doing all that by myself(im also in canada and some pieces may cost higher or are harder to get) so getting the boards from china was the best decision for me in this context.. I totally get and respect you want to go and get that additional 10% if I was in some state or country which sell an oz for 200$ that would be golden but thats half the price of that in here.. all im saying is you still need to respect the others who made the decision to go this route which lets be honest is better than probably 95% of all other available lights on the market in my opinion.. but the way most of the haters talk about it its as if I was buying cheap blurple 2000w with 200w draw power from an unknown brand.. while its not even comparable..

You inspired me to build my own CS generator to create my own femals. I wanted to try it for years but never thought it's sooooo easy. Many thanks, mate!
I have two icecream boxes full of regular seeds(probably thausands) I've created over the past 20 years(20-30 different strains at least..).
But most of the time I simple buy female seeds because my bones getting older and I'm getting lazier each and every year, LOL! Not enough time to plant twice as many seeds as needed and then throw away half of the plants when outing is done.

Your thread about it was really helpful. Already ordered some 1g 999 silver plates, croco clamps and a small 3-12v wallplug(6 settings, 3v, 4,5, 6, 7,5, 9, 10,5 and 12v, 1Amp). I know that every strain has a keeper-pheno that's worth it to resurrect as a female variety.
You helped me finally to realize this project. Thank you!

BTW,
It took me half a day to read the example thread of this aussie grower(with his clone-only indika), LOL! From page 27, really..???...phew! It starts actually on page 42!!.... and then over 100 pages, old Swede!
Although long, now I know exactly how it must look at every single stage! Seems really idiot-proof if you do not change anything (eg different .800 silver or use tap water instead of aqua-dest).

Really inspiring, thanks!

You could get 5 Samsung strips the FB24b is the double row. Everyone's trying to tell you there are better options your savings are so minimal it's really just not worth it. Your getting 4 boards that you have to wire and get drivers for it's the same amount of diy.

The 4 boards came with the heatsink and drivers..(and the boards were actually mounted on the heatsink already) so really all I had to do is plug the cables together using wago connector (easy) and wire to the board just slide the wires in the connectors I mean a 6yrs old kid could have done it.. didnt need to order from different places got it all together and ready to go...

Yes there is other options.. but if you read the thread people are complaining because I purchased from china instead of usa and claiming im missing on maybe 10-20% efficiency out of the most efficient light available on the market its no big deal to me and provide a nice option for those looking to go for LED or newer grower thats all my saying.. but hey its like dallas cowboy fan.. haters gonna hate ;)
