I know you already choose to go with 600w hps, but since you are height limited and heat from hps could be a problem, you should also try to consider a quantum board style grow(or samsung f strip).Better uniformity, higher ppfd with less wattage usage(= less heat) and more space for vertical...

I have found this guy at a cannabis grow product exibition, he was showing some cities 1212 fixture and a couple of prototype.He was quite friendly and we got in touch via skype.I am quite confident his product will be with genuine s6 az bin.Biggest feature is no need for heatsink, so will save...

Can not post any link till 20th of January. Will receive board on 7 of January. 1 week for testing and reporting it to owner of shop, than compare my results with its result. Than if everything is within parameter, I can post link and he will start selling

For European buyers, I am about to receive some boards to test from a shop within Europe.It has 342 lm561c s6 az bin.This shop will also provide me an apogee sq-520 to take different reading from different distance and configuration.They say board is completely passive up to 2100 mA with a...

If you plan to avoid parallel wiring and choose series, than hlg 185 is not enough for a 200 watt BTW, please link other supplier..I would like to see its completr offer:bigjoint:

Yes, they only use citis 1212 3500k.If you are looking for kit with bridgelux or Cree I do not know other sources.If you want more info about board, we have to wait.I saw them at a cannabis exhibition promoting their kits and showing a prototype board.Still under development but seems...

here it is: http://www.flowerpowerbologna.it/epages/99883.sf/it_IT/?ObjectPath=/Shops/99883/Products/1530 they are also projecting board with lm561c

I know a shop that sell kit (hetsink+cob+driver),inside EU.It is not in Uk

Do not know your country, but if you are in Europe there are other suppliers that offer a pcb board ,with lm561c.I have seen a prototype at a growing equipment exibition, (efficiency of 2,7mmol/j at 100w,passive cooling,but I do not remember all data exactly )available from December.

Can I mix 3000k and 3500k of same clu048 1212 if I wire them in parallel or different color has slightly different voltage?

It will get very complicated and with too many wire through fixture. Wago#1 1 + from driver output#1 2 + from driver output#2 3 wire to bar A as +(call it a) 4 wire to bar B as +(call it b) 5 wire to bar C as +(call it c) Wago#2 1 + wire from wago#1 (wire a) 2 + to cob 1a(first cob of bar A) 3 +...

@CobKits Well...if I use parallel wiring, I think that I have to split load equally, among driver output,or not?So if I put the 2 + output from driver, and 3 + wire from bars on same wago 5 pole, than I am splitting driver output in 3 output ,1 for each bar.Than I can connecT 4 cob in parallel...

@CobKits Are you replying to myour question? "hlg-480h has output split in 2 different pair (+and-) of dc.So it has 2 + wire and 2 - wire.I want to use it to drive 3 bar with 4 cob each, so I have to split 2 output in 3.This way I have 2 option: use each pair from hlg to drive 6 cob or (that...

hlg-480h has output split in 2 different pair (+and-) of dc.So it has 2 + wire and 2 - wire.I want to use it to drive 3 bar with 4 cob each, so I have to split 2 output in 3.This way I have 2 option: use each pair from hlg to drive 6 cob or (that what I am asking for) use a 5 pole wago, connect...

Can someone help me?

I have done rapid search and found it on digikey

I would like to use hlh-480h-36a for a 3 bar fixture.Can I put 2 dc output(same + or -) from driver on the same 5 pole wago, to split that output to 3 wire(1 from each bar) coming from bars?Hope I explained it clear enough

Hello everyone, I am probably noob and I about to say something very stupid, but why not to consider samsung f-series gen3 instead of h-series?Based on spech, 560mm model are 23v and 1.12A, for 168lm/watt in 3000k....so 26watt for $10.78 (25 or more pieces).Almost twice wattage for same price...

Thanks. Based on 80cri vs 90cri 1812 grow,I would like to take advantage from 90cri better spectrum and 80cri more par a output. So mixing 6 x 90cri and 6 x 80cri like this: X0X0 0X0X X0X0 0X0X 0=80cri X=90cri ,should work.....or not?

I would like to ask if I can mix different model( 80 and 90 cri) of 1212 3500k on the same diver in parallel. Thank you
