Thanks! I went on samsug site and to get the higher efficiency from diodes (3500k)so about 36lm per diodes driven at .65mA and 0.2w per diode or chip I will get 36lm x 5(to get 1w)= 180lm/w am I correct? I guess only 5000k give 220lm/w!? It lead me to another question what is the advantage of having lm 301b pcb compare to COB? I don't know how many lm/w a cxb3590 3500k DB pull @700mA but it should be close or over lm301b so why should I go with qb or strips?
Strips looks cool I guess it is 2ft strips...i don't know how much it cost but yes twice the strip or more to get 460/500w @ the mA who give me 190/200lm/w!
I believe my cxb3590 3500k CD @1400mA are 160 lm/w if I remember well and they are 185lm/w @700mA so I want something more efficient to increase my yield!
Have a lifted one
I don't think you will see much different between cobs and strips . Cxb are still great performers so maybe you could gain from raising the efficiency , play with light distribution and save on electricity .
Olso heat management is little different but watt a watt is the some story and the ratios gr/w probably go up .

Yes I want to build it but like I said I wasn't on RIU for 2 years so I have a lot to read about qb's and Samsung diodes! I know how cxb3590 can do as I have made a lots of panels @1400mA and 700mA...i know there is a big weight and heat and watering and nutes difference! So I was wondering what even more efficient lights could pull in gpw!
If DIY is not possible or require too much soldering with Samsung diodes I will go another way but I really want to have this kind of light...something almost as large as a 4x4 or 4 time almost 2"x2"(I guess it would be easier to find) and spread diodes to have 100w at the mA who give 200 lm/w! If I am correct it will be 288 x 4 =1152 diodes x 4 so a total of 4608 diodes spread as evenly as I can! Is it sound crazy is there other people on RIU who DIY Samsung diodes! I will not start to build it tomorrow I just want to know if it is possible or not? I pray for a yes cause if it grow like I think it grow I would be able to get the same weight for less electricity so I want to give it a try!
Have a lifted one and lots of good vibes from France growers
Strips brother, Samsung F-series strips or H-influx strips.
