Via card? only the 3000k are available for purchase over at digikey. I will be posting the build when i get everything together, I'm expect I'll have all the parts by mid-end April. Lol, count me in! Put up pics of your build too! I doubt I'll use holders, it would be too much hassle and...

Just placed my order for 24 cxb3590cb, tears came to my eyes at the price! It will be worth it in the end though.

Thanks for that Supra, looks like the cxb3590cb is cheaper for me than the cxb03070ab as i would need 32 3070s but only 24 3590s and the 3590 puts out more light. But should i sacrifice a bit of power for light spread with the cxb3070... it's a tough one. Also if go with the 3590 i can cut down...

I'm planning on keeping this design for around 3 years. By then, I'm assuming, there will have been some pretty good advancements in LED. I'll probably get a whole new setup and use these heatsinks for my veg area or side lighting or something else. As long as they can handle the load I'll be...

They are big enough to be passive according to supra? If you look at the Thermal performance it's actually better then the 3.5" from heastinkUSA... I think that's right anyway

Damn all this talk on here about CXBs! It's put my plans in a state of disarray. I'm now contemplating either 16 cxb3070ab running at 500ma per level or 12 cxb3590cb running at 350ma per level (assuming they do actually get released to us). I've not done the figures yet to tell which would be...

@SupraSPL What is the math behind the efficiency numbers? I'm sure i've seen it somewhere on here before but i can't for the life of me remember where. There's just too much info crammed into single threads over here. We could do with some stickies that have just data in them, or i suppose i...

That's for the 1050ma, the 450ma goes up to 444dcv

Thanks for the driver recommendation, i'll keep that in mind. Well i can get the Arctic alpine 11's for £10 each over here, so for 24 i would be looking at £240, plus 2 of those drivers brings it up to £250.24 and then postage on top. For passive heatsinks i would need 8x1meter if i were to give...

Damn that would have been perfect for me, 13 cxa3070 running at 450ma, shame there is a 50pc minimum order, i would only need 2 :cry:

I agree, but i'm in the UK, i've not looked at shipping prices but i imagine it will be rather large, and then there is import tax to think about. We aren't as far into LED as you guys over in the states unfortunately :cry:. I may be able to find somewhere to get some decent sized heatsinks but...

well that sounds good to me haha!

I have built myself an 8 x cxa3070 Z2 (couldn't get the ABs at the time) drone running at 1.4a on the meanwell lpc60 1400s and it has been working wonders i managed 0.95gpw on my first run with them, but... I am planning on splitting my area into two levels, it's going to be tight on hight but...

Ah, my bad, i wasn't looking at the input numbers. Thanks everyone, told you it was a silly question lol

I have built myself a 8x cxa3070 grow light similar to goud's battlestar ganjatica, each running on a MW lpc60-1400. I have a kill-a-watt style reader and it's telling me that at the plug i'm pulling 484+/-watts, 239v and 3.09+/-a... (just LEDs, no fans) surely that isn't right? I thought it...
