Help me understand LED cobs

[tk9119]

I have been looking at some cree cobs and they have different bins, so what is the difference in the bin where I have looked it don't tell what the bin is?

Bins define within a given CCT the flux(brightness) they work in alpha so BD is higher flux than BB etc

For the time being to my best understanding, cree have nothing to match the latest citizen, bridgelux vero gen 7's or luxeon gen 3's but I'm only going by the spec sheets on the cree and citizen at the moment. If money was no object, I'd duplicate our luxeon gen 3 rig (awesome results), if I were pressed fer cash then it would be vero 29's gen 7(will tell you in about 3 months!!).

Where do you find the bin code like in this num.
CXB3590-0000-000N0HCB30G

 

[CobKits]

N=36V
H=80CRI
CB=bin
30=3000K


you can learn about all that and more on the datasheet

Sorry, what does CCT mean and what is working in Alpha?

if you use Meanwell HLG-320H-C1400B on 4 cobs believe it draws 300 watts at the plug and puts out 300 watts if you put 5 cobs on that driver would it still be the same 300 watts?

tk, spend a day or two reading this, then ask questions (in that thread preferably)

colour corrected temperature, refers to the colour temperature within the white range of LEDS

Thanks, that's pretty straight forward. I hadn't come across those abbreviations. I would have assumed that alphanumerically BB in your example would represent higher quality than BD.

no it works up the up the alphabet not down

sort of. Ys and Zs flipped around to As and Bs a year or two ago
