Hi guys Perhaps some more info will help. I bought "regular" ones, that is with no extra red leds. I bought 6 boards and 2 heat sinks, 3 boards on each heat sink and 1 320w driver for each heat sink. I've used them for 2 grows and it worked really good. Unfortunately couple of individual...

Yes it's Chinese company, I picked 3 different companies and they all seems to have good reviews on different forums but yes you never know I guess... But then 99% of everything electric I have at home is made in China in one way or another. I bet if you crack our planet in 2, in the middle you...

Perfect, the last like helped! :D https://www.r2thk.com/QB288-V2-Samsung-lm301B-SK-full-spectrum-Quantum-Board-600W-LED-Grow-Light-with-XPE-660nm-for-hydroponic-system-growing-pd6850328.html

Well its more or less this one but I will have a different layout, mine will be 3 boards in a row on a heat sink and I will get 2 of those so total of 6 boards. And the drive for each hear sink (3 boards) will be: HLG-320H-54B This is 6 boards all together with a HLG-600H-54B, but the boards in...

I could actually save myself some money and buy "regular" qb288 lm301b boards instead, no added 660nm. If nobody actually thinks the added 660nm will help that much then why pay more for something that perhaps does not help that much?

I bet it would be hard to say anything with the small amount of data provided by me :D I also have understood that more 660nm spectrum will often cause more stretch, but since I grow autos I don't mind stretch, perhaps stupid thinking from my part? I have attached a pic for Option 1, this data...

Thx mate! But I have to say that I'm not really following you (really new to leds). The option has never been the add more blues, Airwalker16 wrote about changing some of the reds to blues. My 2 options are basically what I wrote in the thread start: " Option 1: Would you guys go for more...

So what does this mean? :D If you had to choose between the two, what would you choose? I'm leaning towards conf2 which has the same amount lm301b leds as for example hlg v2 boards but it also has some extra Cree 660nm leds which should make it a better option. Conf1 has less lm301b leds but...

I don't know as much as I want when it comes to led, so bare with me if questions are a bit stupid :D Why would I get more blue diodes? The showed me spectrum graphs on 3000k, 3500k & 4000k. 3000k had the less amount of blue and 4000k the most. Both companies recommended 3000k for full cycle...

Hi guys I'm looking into buying QB boards and I have 2 configurations I wanted to check with you all. I will buy 2 heat sinks, depending on conf they will be either 940mm or 900mm in length. Each heat sink will have 3 qb boards on them, the difference will be number of white Samsung lm301b and...
