Thanks so much man lots of good info, I been reading like crazy about it all. Gonna start building my 4 cobs light here soon and I'll post pics on it once I've gotten everything for it and putting it together. Thanks again Supra!!
I just bought the ebay ones you linked for $11 a piece...that would be $33 for the drivers instead of $70
They are both made by meanwell, and that's what I thought but I have seen several people running the 3070s with them. Which leads me to believe the cobs will. Only pull what they can.
No.
OK, thank you, I will keep that in mind, but has anyone been able to find if I can successfully run the 3070 cobs at 100w a piece(8 drivers) ? Or two cobs at 200w(4 drivers) for a total of 800, still Need the right drivers to get the job done.
Exactly why I am here, thanks for your help bro, I'm Not buying anything until I fully. Understand the electrical Aspect of this. Ok did some reading an forgot a few deets when reading that the cobs will only pull at 38.4v and max at 2. 8 amps, so to get 100w per cob I need a driver capable of 38.4v x 2.5amps = 95w, I will probably go with the cen-100-42, unless anyone specifies otherwise.
i saw the veros they were a heck of a lot cheaper but rom what supra said they arent as efficient or nice on the spectrum balance, if i do get the vero 29's which ones do i get the 3000K or higher, i read several places the 3000K is not the same as the CXA 3000KIf you are looking to run them hard I believe Supra and several other guys have stated that the Vero 29 may be more suitable then the CXA3070.
I think the Vero may get you closer to what you are looking for
Why not go for a target of 80 watts per COB? much easier to achieve and may save you a few bucks, not to mention allow the LED's to last a little longer. Remember, we are running these for a pretty large chunk of time, 18 hours on these LED's is no joke when it comes to the heat they can produce. Especially when run at 2+ Amps
hmm interesting, yea i know supra will have the answer he always seems too, and yea i want to use the same light from veg to flower i was planning on slapping on 1 xpe2 blue and 1 xpe2 deep red next to each cxa 3070 or vero just to add soem extra spectrum and also have them on a switch, so the blue will be on during veg and red off and red on and blue off during veg.
Yes you would need to paste it then strap it in place with kapton, or use the COB holders +paste + drill and tap. The Prolimatech PK3 and Arctic MX4 has both performed well in my tests but I have not tried AS5. I expect it would work fine though. The paste you linked has less than half the conductivity of PK3 but would still probably work well.
