The KB ones.Which ones are you referring to?
The Kingbrite bars or the ones from R2T?
Edit: Reason I'm saying KB is the prices being quoted for delivery to the UK by R2T are way higher than KB

Thx man. Hows Oz? My cousin and Tek says your almost out of it, ready for the Big Turd at the end of the tunnel: great depression re-run. Dont even wanna think what Spain is going to be like. Most people around here dont really feel we got over the last one.From memory it was the edge holes. I think I have a thread about it somewhere here.
The Sunlike is a 415nm pump, so that's where it peaks. I haven't calculated the SPDs, so I don't know exactly how much 400-430nm there is, but looking at the test report it would be about 1.5-2%.

It's better here, but COVID19 isn't really going to go away. There will probably always be outbreaks, if not continuing mutations sweeping around the world like other coronaviruses. It could be 5 years or more before it's truly under control, with either a vaccine or most people getting it and developing some form of immunity or least some sort of resilience. Some people don't seem to be affected by it that much but others die. I guess there are many contagious diseases that have killed humans throughout history and this is another one we need to endure before we overcome.Thx man. Hows Oz?

It's hard to say for sure without the full electrical characteristics of those bars.The KB ones.

I cant really say anything about this board except that it looks like all the rest, i dont know the seller, and that they are lying/overstating the specs: 250lums/w is not possible.@Rocket Soul I saw that you have understanding in quantum boards, could you tell me if it is safe to buy this? In a matter of quality x price. It's at a value below the ones I found on alibaba, and it has the same config;
I had asked a question earlier but the friend indicated to me the video of the migro where he only talked about the driverless. In every topic I did not see about the yxo boards. Starting from the point where the diodes are all samsung/cree/osram would be of equivalent quality to the ones you usually buy on kingbrite alibaba?
I get it, it's clearer now, so even though samsumg diodes still have the possibility of not being of good quality?I cant really say anything about this board except that it looks like all the rest, i dont know the seller, and that they are lying/overstating the specs: 250lums/w is not possible.
Kingbrite/meijiu: ive used them and they give you something close to what they claim at least, but probably not 100% top bin.
Honestly, what could anyone say re this board based on a picture?
Id avoid any AliExpress deal tbh, never heard anything good about them. And the link to supplier seems to not work? And its no bother, i get it cause ive been there myself. Its really hard to pull the trigger the first time, right? And you want to get assurances from someone? But sadly its hard to give, and everybody goes thru this decision angst re supplier, extra reds or not, uv to the point that it paralyze you when really the only thing you can do is try.I get it, it's clearer now, so even though samsumg diodes still have the possibility of not being of good quality?
This product is from an ad on aliexpress, i haven't even seen a comment on. But for having an affordable price and being samsung diodes I thought in turn would be useful.

Thanks for the clarification, and I'm sorry to bother you.
He used post quite a bit on riu back in the day.I don't know if anyone here uses Instagram but if you do check out a guy called sixstring, his led builds and grows are killing it!
this is a great thread but everyone should not use the "quantum" board name..@Rocket Soul I saw that you have understanding in quantum boards, could you tell me if it is safe to buy this? In a matter of quality x price. It's at a value below the ones I found on alibaba, and it has the same config;

Totally agree, can we make it China boards? CBs?this is a great thread but everyone should not use the "quantum" board name..
sure they did not invent the samsung diode led panel
but they did make up the name "Quantum Board"..
just because China uses it on their knock offs...we shouldn't
sure ..these China made Boards rock..and yes HLG started first making them there..
but only they should get to use the name

Any knowledge around here is based on people trying something and then sharing.
I got to meijiu from moflow trying some boards and showing parmaps; i decided that this looks good enough for me to not care about bins. And ive been mostly happy with the gear. But since then, like 2 years ago ive not really seen any doing parmaps or comparisons so anything new is hard to say. As a general advice: buy from places where people have done business before with not too much probs: meijiu, kb, r2t and maybe bava.
If your planning to run your boards soft then the difference between top and mid is less important. And you can also improve on your actual "light on the cannopy"-efficacy thru design, getting the spread right. Ive never bought a single kit,only boards that ive set on alu to get it to work for my space. The 240 kits, to me, might be a decent deal but they are imo over powered for the spread they have. Too much light in the centre and little on the sides for a 4x2. Better use them for maybe a 3x2 on 180w.
Friends, thank you so much again for the clarifications. It helped me a lot to make this decision, every investment that goes a little money, we need to think about it. I will forget these aliexpress boards and i will kingbrite because it is the most recommended in the community.this is a great thread but everyone should not use the "quantum" board name..

For that space your already way over powered, its basicly a 2x2, right? You also need more height to do decent growing, you lose alot of height in hanging height and pot height and filter, like almost a meter.Friends, thank you so much again for the clarifications.

Thinking about what you said @Rocket Soul , that the 240 kits have more light in the center than on the sides, would it be more interesting to take two of 120 and put one on the side of the other, horizontally? Instead of the way in which they come mounted, vertically. My space for these QB is 60x60x1.40 (width x depth x height)
Have a look at @bigmikey86 setup he posted on this thread a bit back. Basicly: 6 boards, and you wont need much more than 480watts.Hi guys any suggestions for 4x4 tent
Looking for something killa and uniform spred
put my eye on kings bright or meijiu but not sure on wich boards or strips to go for
Yes, I believe that 240 is a lot for this space, so I think about rotating them with half the power, thus making 120w in the sum of the two, according to what I know when they work with the lowest power, has a higher efficiency, generating more ppfd.If

But youre right, better spread the boards out, and even better spread the watts outnover more boards. I dont do 120w qbs, period. 60-80w is good for me, enough to work with alu backing instead of heatsink.
