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
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 optionHi!

because lumens are for humans, plants like PAR, and certain ranges are more absorbable than others, so not allPAR is even the sameHi! How much does those COB cost? And why 90 CRI? They are only 129 lm/w @1400mA! I
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!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
