340 pound is cost for 4 single cob of 60 watt each.340 pound are 385 eur@G84 you are talking about that boards right? Don't I need some passive heatsink? And driver?? As i saw I would need for for my 1m2 tent..
board is 80e x4= 320€ plus driver 50€ min. plus heatsinks..
how is that cheaper than 290pounds or should i write 330€??
Yeah..try to add shipping cost and custom fees..that ' s why I have been waiting for Italian board so long.Now the Italian board shop are the best deal if you are in EUWhat about this??https://horticulturelightinggroup.com/collections/diy/products/135w-led-board-kit
I can buy for now one kit add my 55w cob and later buy another one?
Sorry,my fault.Now you have message.My inbox is empty. I',m lost now..whats are your boards??
tgl sell quantum boards too. 200€ for 134w assembled... https://www.todogrowled.com/gb/hlg-quantum-boards/55-hlg-260w-quantum-board-kit.html
But I need some heat so For now I think my best option are those 3 cobs...
And who will connect that? i don't know shit about serial/parallel wiring .. my buddy did my cobs for me and he moved out..Sorry,my fault.Now you have message.
Regarding cob, board and heat is the same.If you put 240 watt of whatever light inside a tent,you will have same heat output.Hps can leaD to an higher leaf temperature since hps has more infrared output.But with led, 240 watt of cob or board will have same heat output.
Todogrowled prices are higher than Italian shop.
Again 1 board is 80€
3 board are 240€,
1 hlg 320h is 103€
For 343€ you will have 3 board at 110watt each,passive with no heatsink.Better efficiency and better uniformity compared to todogrowled 260 watt kit at 319€
Of course is even better comparing it to cob.
But it seems to me you already choose you want cob,no matter what.Cob cost more,have lower uniformity and lower efficiency but if you are comfortable about them, than go with cob.You should choose what you prefer
