just bought from arrow 17pcs of BXEB-L0560Z-30E2000-C-A3 and a MW driver hlg 320h-c1050a for the vero 29 gen 7 C , the idea is to mix the strips with the cobs , 15 strips @700ma , pulling 230w from the wall and the cobs driven at 1050 ma , pulling 300w from the wall, the tent size is not set...

thanks @nfhgiss and @danielson99 for the heatsink examples, also the words of @Chip Green made me decide to buy the EB strips, the first option is : 15 pcs of BXEB-L0560Z-30E2000-C-A3 , running on the hlg 240h-c700a , using 331 vf from the 357 available and 230 w of the 249w The other 2 options...

well, thats a very good point, i can only get an aluminium frame around here, and if i go with samsung strips maybe that is not enough to cool them.

Hi to everyone, right now i am growing with 4 vero 29 C, driven with a hlg240-c700a, the plan is to buy a hlg 320 c1050 and use the 240 for strips, mix cobs and strips in a 1mx1mx2m grow space , the price of EB series are great...

yeh, it's just in case i want to run them higher, but i think that 70w of each cobs are fine, anyway i found this heatsinks for cree, https://www.arrow.com/en/products/lmh020-hs00-0000-0000081/cree, maybe they will work, if not ,going to choose the heatsinks from @CobKits Cya

good to know, i am running 4 vero 29 C with a hlg 240h-c700, with active cooling, i would like to run these cobs at 1a or 1.4 A, , do you thinks these http://www.rapidled.com/140mm-pin-heatsink/ would be enough for 70w-100w? Cya

Re-wired everything with 0.75 mm wire, similar to 20awg , and took some chains off

Great man! Found some of that sinks in arrow.com, the cree ones of 133mm and 153mm, maybe going to buy those. Indeed they are used got them from my work, so for now i Will use them until i can buy some new fans or go passive. I bought 1.5mm cable and did not fit, so just cut some hairs and did...

Greetings from Argentina to everyone! glad to show some pics of the almost finished setup , 4 Vero 29 gen 7C 3000k, 90cri, BXRC-30G10K0-C-73-SE, mounted on CPU heatsinks, with a MW HLG-240H-c700A. Maybe is not the best setup, but is the best thing i can get without paying to much costs of...

thanks everyone for response, first time i am building a cob lamp and i thought they were as fragile as microprocessors , the driver arrives at Wednesday so i will post pic's when everything is setted up!

So, i was happy today when i went to the fedex facility to pickup 4 bridgelux vero 29 gen 7 SE chips that i bought from arrow.com, the model BXRC-30G10K0-C-73-SE, those are 70v ,3000k and 90CRI But, when i opened the box,first of all, the products that i had ordered was the BXRC-30G10K0-C-73-SE...

amazing, really taking eb series into account for veg, i have the hlg 240h-c700a , so 7 or 8 of 44v EB or 15-16 of 22v EB i think may fit :).

wow,i have a 700ma driver for some cobs and now i am thinking to run the cobs at more current and buy some EB series for this driver, you mean only mounting the modules to aluminum strip and thats it? Cya!

@The Dawg Amazing thread man, i read all the 24 pages and learned alot, i am planing to setup some citizen 1818 3500k 90 cri and this convinces me more, cant wait to see another comparision! Cya

i just found another reseller of MW here in Argentina with a ver large catalog of MW, included constant current and constant voltage drivers, sended them an email so tomorrow i hope i will get an answer. Again, thanks a lot !!!

ofcourse, I did not take that into account , i can get 2 hlg-120h-c700 , constant current of this model is 107v-215v and run 3 citizen's in each, the other model that i can get wich is hlg185h-c700a got constant current 146v-286v , and run 4 citizen each, but those extra 36 V, could be a...

perfect, i am going to buy an MW driver here in Arg. ,model : hlg-240-h-c700a( i cant get any driver of more mA) , was thinking of 6x luminus cxm22 3500k 90cri, or 6x citizen 048-1818 90cri , plus the 6x Ideal holders and the 6x thermal pads, all with active cooling. Do you think this could be...
