That would make a nice coin.

SDS good catch on the CXA bond wires in the design guide. I was thinking Cree could be using many of the lower current DA2432 die in the COB. I'd consider using one of the Cree direct attach dies in my COBs if the capital cost to bond eutectic dies wasn't so high... Fortunately there are other options

So rolay!

Alright, who the fuck bought out all the Vero 18 3500K's and 4000K's (80CRI) from Digikey?!!?

I can only guess that DK is waiting for the new V.2's to take launch before restocking. Does anyone have any clues on when the V.2's are being released for purchase or are they already out?

 

[churchhaze]

I don't know where they are, but I can't wait any longer! I need 12 vero 18 or equivalent right now!! I'm even starting to look into the smaller cxb things. I actually need them a week ago.

What I really want is a price reduction on vero 18 version 1 before I pull the trigger... I'm going to have to take a hit and buy them now..

I'm only going to get 3000k from now on as well. I'm thinking 3500k would be better for ripening since I have 12 of those already, or i could evenly distribute the 3500k and 3000k to make a mix.

DK has plenty of 2700K, 3000K, 5000K, and 5600K but no 3500K or 4000K @80CRI. Yeah, you'd be wise to see if DK or Newark will reduce pricing on the current version.

@stardustsailor may know about when the availability of the Vero 2.0 comes to be. I was reading a thread a moment ago and someone apparently got some Vero 18's @ 20% off from Newark recently.

All 80cri 3000, 3500 and 4000k Vero 29 are 0 stock as well. Maybe there is about to be a new commercial COB-based lamp line-up on the way.

Are you seeing into the future or?

Do you think it's someone here? Is it you buying up all the damn Veros?

 

[ReeferDance]

Amazing.........

No drivers from China right now. And no Vero's from Digikey.

Some people just want to watch the world burn

Trying to time planting seeds around worldwide shipping and stock is near impossible. My poor little seedlings will have to suffer longer under the cheap 100w warm white COB's

I just hope they don't outgrow the light before I get this new one built haha, should be interesting. Just need to sit back and

 

[churchhaze]

VERO OR RIOT!

Not me but im glad i grabbed the 8 V18 4000k when i did.

 

[hyroot]

I'm glad you guys dont like high cri cobs. Even though you guys never tried them. They wont sell out and I can grab all the high cri cobs I want. 90 cri spectrum is far better than 80 cri spectrum. Even if its not electrically efficient as lower cri.

 

[doctorflux]

90 cri spectrum is far better than 80 cri spectrum

I dont have my spectrometer or any veros on me right now; what about the spectrum in your opinion is better? Smaller gap at 490nm?

the higher the cri the more even the spectral output and better the performance. I've seen first hand. My inda gros put out 800 µmoles and has 95 cri and out performed leds putting out 1100 µmoles at 80 cri. Imo cri trumps over par. If both are high like CMH then that's even better l

REALLY interesting. I've been working on various tricks to level out the spectrum and fill critical spectral gaps in some of my devices over the last few months. It's nice to hear that this truly makes a difference

Keeping in mind that it has been hard journey for LEDs to rise to the level that we can really beat HPS. HPS does a decent job flowering, CRi 24 and arguably a poor spectrum for flowering. The reason it was tough to beat is simply because of intensity, or the amount of photons reaching the canopy. HPS buds:


Another data point, we see a huge improvement over HPS from red/white/blue LEDs with very low overall CRi. This is the same cutting pictured above, but grown under low CRi red/whie/blue LED:


White LEDs take a major hit in intensity just by going from 80CRi to 90CRi. It is hard to accept that a slight change in CRi would be worth the trade off of losing photons and increased heat. So I encourage growers to stick with 80 CRi Veros but to each their own

 

[SupraSPL]

@churchhaze I believe this is the top bin 3000K CXB1816
http://www.digikey.com/product-detail/en/CXB1816-0000-000N0HQ230G/CXB1816-0000-000N0HQ230G-ND/5124965

Not sure if it is a suitable alternative for Vero18 because it has a higher Vf and seems more expensive, but I don't have charts on it to check $/PAR W. At 450mA the CXB is higher efficiency but similar cost as Vero18 @ 350mA. Might be a close match if you run them harder.

All the Veros being sold out could be good news, maybe they will restock with V2.0s

I totally agree. Higher CRI LEDs have relatively higher output in (deep) red. The thing is that in absolute numbers, their low CRI counterparts do have the same amount of (deep) red and a boost in all other wavelengths.

Wait, what? Your second and third sentences contradict one another.

Are you referring to HPS when you mention counterparts or 70, 80 CRI LEDs?
