Then in that case you just don't know how to use them, don't blame the technology. Tons of people (I've seen them here, other mj sites, offline) have switched from hps to COBs and had great results and certainly much higher gpw's. So it's either your skills or you have some agenda, maybe both.
50W of CXB3590 replacing each 400mh (hort eye blue), is it as bright, not even close, do I miss anything, nope not even the heat
So it's my fault all these led manufactorers make false claims of just about every damn led can replace a 600 or 1000w hps? totally has to do with my growing skills. I have had good results with leds , but they aren't magic lights like you guys act they grow plants just like hps does, no difference in quality to my knowledge and they cover less area and cost more so yea what's the big deal about them? Yea they are a bit more efficient but they don't have the coverage yet so I don't see the big deal, the led this guy makes only covers a 3x3 but its a 1000w replacement? give me a break.
Bro youre a cowardly liar. Your claims, stories, examples are all suspect because you straight up lie.
People are getting similar returns with a 315 lec...still don't see the point of spending 10x more for the same results. That's about the same results as a 600w hps as well in a tight hood.
It just states "Specially designed 98% transmittance optical glass" which I'm cool with. I don't expect this light to solve all of my lighting issues; high power bill, heat exhaust, big ass magnetic ballasts Cuz the damn nice digital cause significant rfi where I live. I just need this as a bandaid until I have time to wait on parts for DIY which I will definitely be doing. PLC and the dude that apparently runs it seem to be straight up. I've watched other vids of his and have much respect for his line of thinking. I'm changing the way I think, more toward quality and not quantity. I think the quantity will be comparable once I completely transition to led. All of the expense to match or surpass hps is front loaded, that's all. The foot print is smaller, yes, that's the reason to diy. But for the money, and my current specific need plcs 420 is perfect. I am well aware of the data. I will never hang another 1k again. I really do appreciate everyone's feedback. Exactly why I'm in these forums.
You do know I agree with you on that, right? After using the ViparSpectra, I did realize that it's just worth it to lay out the extra $50 for a high amp COB. The Vipar wasn't necessarily useless, because I was able to grow a few ounces of non-larfy pretty quality bud, but I knew I wanted a more efficient, more powerful COB to start my next grow with.
This is copy pasted off their website....
No one is calling them magic bullets but many growers are very pleased when their gpw doubles or triples using the same wattage, or significantly reduce their wattage and pull the same weights. or get high quality buds and yields in tiny spaces. That's why they are hyped and why you hear so many positive comments on them from real world users, not manufacturers.
I ran the same cut of golden goat for the last few years under hps, and leds, not a huge difference in quality between them, more weight with the hps (also more watts and larger growing area) , don't see the big deal , quality is mainly determined on grower skill and genetics.
So what's so unbelievable? The only one that would be questionable to someone that doesn't know COB's is the 1000 MH but if you look at the output of the 5000k CXB3590 you would know it's a monster.
I don't question the output I question the coverage, no way in hell you can grow the same amount in a 3x3 as in a 4x4 or 5x5 if all are lit properly, yield is mainly determined by properly lit grow area.
except a 1kw gavita puts out ~1000 umols in 2 squared meters and these only put out 900 in less than 1....
I thought the argument was just about 600w HPS, 1000w MH, or 315 LEC. I don't think anyone's arguing it can reach 2k PPFD.
So arguing it can replace 1000w light but not another, i'm calling bullshit on this one, it's not a 1000w replacement, its not a 600w replacement, its a 400-500w replacement, it covers a 3x3, 600w hps in a proper hood covers a 4x4, 1000w hps covers a 5x5, 400w hps covers a 3x3.
