Highest amperage I'm running through a Vero29 right now is only 1.8 
Waiting on a dimmable 150w driver that will run a new Vero29 (Once Digi-key gets them
) at up to 3.57 amps. I want to see how one chip, does with one plant. Should be fun!

You pay for a select potential efficiency when you buy Cree (CXA, CXB) or Bridgelux (Vero) COBS.
What I mean by potential efficiency is the possible efficacy's given by the product and because Cree sports the highest potential, they also get to charge the highest dollar for their products. Bridgelux doesn't focus on efficiency as being it's selling point and rather found it lucrative to establish their own niche, which is a packaged deal of affordability, simplicity and with potential efficiency slowly rising.
The catch that people sometimes forget when running COBS low is that they are ultimately reducing the total watts being ejected from the COB, thus requiring more COBS to be positioned in a given area. So on one side, by lowering current, you get less heat and a better mixture of PAR W (due to higher efficiency, lm/W), leading to cheaper electricity bills, but that money you save goes right back into buying more COBS in order to cross the required PAR/W finish line.
In short, there are two extreme for a given COB: running it as low as possible but getting a great PAR W % but emitting little of anything at all or running it as high as possible, getting more heat than anything but still producing a bunch of PAR W.
The best thing a person can do is find a peaceful middle ground for the time being and in a couple of years, splurge on newer versions and not get heavily invested in current gen technology, because it hasn't hit it's peak.

Agreed...
Leds just needed more oomph, the little ones weren't cutting it. Build a cob light and enjoy it
Theres considerable scalping going on with cobs right now. $90 for a 3590 at mouser is f*cked. I'm glad kingbrite came around and gave them some competition. The market needs to stabilize.
Good on bridgelux for providing a more affordable alternative

$90 for a COB? Wowzers. If money weren't a factor, would the CXB3590 be considered the best available COB on the market today?

I don't count pennies..
Meaning, i don't worry about relatively small differences. 3070, 3590, and vero 29 I consider all in the great led category. But given a choice and all were the same price i would choose the one with the most dies internally. Mechanically built to provide more light. Assuming both are similar in performance. A big multichip isn't in the same league yet. Within reason of course, you only need so much light from one source. But a 3590 and maybe even larger in the future would be my choice.

Looks like the vero 2.0 in vero18 is now availible on digikey, the wait is over

Awesome. Just a few more weeks for the Vero29 hopefully!
Anyone else getting an error when trying to pull up the datasheet from digi-key?

I'm 60 so my Vero 29 build will out last me. I'll just enjoy my retirement soon. Thanks to all of the info on this site an enjoyable one.

For the new version the second to last digit holds a two instead of a zero.

Hi all, just I am a bit confused with the new vero 18 series.
If this is the old vero 18 http://www.digikey.es/product-detail/en/BXRC-40E4000-F-03/976-1155-ND/3913134
The data shows it has an efficiency of 129 lumens per watt at the test conditions
If this is the new versión vero 18, same 4000 K 80 CRI that the other: http://www.digikey.es/product-detail/en/BXRC-40E4000-F-23/976-1271-ND/5180243
In this case efficiency is 126 lumens per watt..and it seems to run on less voltage...
Should not be more efficiency cause is a new versión?
I am missing something?.. maybe I didnt understand the data...
Sorry about my english , and thank you in advance.

I'm under the impression that the efficiency for the newer makes are better than the previous makes but I haven't actually tallied all the information in excel to confirm this.
Just by eyeing the two, the difference in voltage is surely to explain some, if not all, the difference in lumens BUT I would like to think that the lower the voltage or amps, the higher the lumen per watt value.

Seems that driving them at 1.05A ... the new take less power to run..but gives less efficiency at the same amps...a bit confusing way to market them....
By the way nacho is the short name for Ignacio in spanish..I think the nachos mexican food were named after the mexican guy that invented them..he was named Ignacio.
