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!!).

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?

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.
