I'm getting cob envy with all these new cobs popping up...:fire:

Ahh well....my "old bins" still keep me pretty happy

You can recognize the V2.0 series at the penultimate number which must end on 20's number, like 23 for 3step or 24 for a 4step binning. 2.700k, 3000k and 3.500k witha 3step setup are aviable atm.

Lol! Think your rig is still doing a good job.
The Ferrari of the last year is still a rocket today!

Was fooling around and stumbled across some changes that took place with the new Vero 18.

Take a look for yourselves (the new data is depicted on the non-colored graph).

Old Vero 18 Color Spectrum.png New Vero 18 Color Spectrum.png

110% ?!?

By the way, I could have done a better or more complete job then whoever it was who created the newer graph!

:lol:

I would like it if they made multiple graphs for every different make, such as 3500K 90 CRI or 2700K 80 CRI.

Keep in mind those curves are not relative to each other, they simply placed the peaks at 100% so anything with a tall peak will look worse and anything with short peaks will look better. So the difference in absolute output between the color temps is not represented in the graph. That easily gives the wrong impresssion and explains why high CRi looked so good on many charts.

The Vero29 3000K makes 10475 lumens and the 4000K makes 10875. That is an increase of 3.7%. But taking into account Alesh's QER values, the 3000K makes 4.7 umol/PAR W and the 4000K makes 4.62, a difference of 1%. So if we assume that each Vero is making close to its typical output figures, the 4000K should be about 2.5% more effective.

Not saying the 4000K isn't awesome, just not as awesome as that graph is making it appear.

So basically, get what's available because it won't make much difference?

Lies. All lies.

:wink:

(I'm kidding, you are no liar, Supra, but instead a revealer of truth)

This is disappointing news, as the graph did make the 4000K look like the best choice and it was depicted the same way with the past graph, which first led me to buying 4000K COBS.

When it comes to choosing COBS, should we, as growers, generally favor more umol/PAR W or higher amounts of lumens?

Lord, does this question remind me of being a Mage on World of Warcraft and wondering 'do I want more spellpower (damage) or better spell hit (accuracy)?'.

:lol:

Definitely µmol/dissipation-J or at least radiometric (PAR) watts. Lumens just don't tell the story.

Would these work good for vero 29
Lpc-60-1400 $20
Lpc-100-2100 $30
Lpf-90-42 $45

Would cen-100-42 suit better than cen-100-36?

Hey Robinn
Yepp! They will work!
The first is good for ø51w, the 2. one for ø79w.
The cen-100-36 will work but the safer choise in my opinion is the cen-100-42 because of the higher voltage. On both drivers the V29 needs ø37-38v, what means the cen-100-36 will work outside of its range. Although the 36v driver is at first probably a little brighter of its higher current, but in the long run may be too hot and early failure of the power supply is preprogrammed!

Thanks
If120v ac COB were possible, then no driver will be needed.

I can see the high powered cobs eventually being self-driven like this link
https://www.superbrightleds.com/moreinfo/led-spot-flood/led-ar111-spot-lamp--12-watt-cob-led/1845/
Something similar would be great if they were in modules of some sort so you could have a frame system and just swap out the cobs as different spectrums are desired or a new more efficient model becomes available

Hi OHD!
They need 12v dc and also a driver! Also also don't believe the 1.660lm @12w!
If you use Vero's per example with the molex connectors you can easily change it. And also with CXA/CXB and the cobholders it is easily possible to change the cobs.
Cree have also some efficient downlights modules(LMH2-6/LMR2,...) for systems and the biggest can create 8.000lm. But look what they costs!
