this controller can keep 4 clu048-1212 3000k cri90 in 1400mA ?

Hi! How much does those COB cost? And why 90 CRI? They are only 129 lm/w @1400mA! I guess cxb3590 3500k CD or even DB now would be much better in efficiency and more effective than those and they cost 30$ each or around! So why did you choose the citizen? It is just a question as I wasn't on RIU for the last 2 years so I have to catch things!
I miss Supraspl...where is he?
Have a lifted one

clu048-1212 3000k cri90 has better spectrum

a good cxb costs and heat twice, i have a tent 60x60 and I'm not interested in producing heat.. it's the main reason why I change to the led..

The clu48 1212 were like $10 last time I checked (about a year ago) they are better running at 1000ma or less for 1400ma up bridgelux would probably be the best option

because lumens are for humans, plants like PAR, and certain ranges are more absorbable than others, so not allPAR is even the same

lumen is a green-centic measurement and is not very useful when comapring different spectrums

Thanks!!!...but I need proof! A grow log would be great...i know lm/w is not the best way to compare light but it help a lot! What I am looking for is gpw (and quality of course but quality is not 100% related to lights) the best light for me is the one who grow the highest gpw!
So which led are growing the highest gpw these days! The highest I ever saw from a reliable source(I can make a grow log and lie about the final weight it is hard to verify but there is reliable people here) was almost 2gpw from cxb3590 3500k CD @700mA!
Same for qb's people want it because of the 220lm/w not par!!! If I was looking for par I would go with chilled boards!
I know lm/w are not everything but the more you have the more weed you harvest(at least in my case!)
