No, you are correct to some extent; this 5 square pattern exists. I searched pretty exhaustively on digikey and there exist OSRAM GDP part numbers with that sectioned design:

 

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=475-260...

 

The pattern I'm able to discern (I don't know if it's 100% as the OSRAM datasheet nor any of their application notes specify this) is that of the "pure white" parts, the 6500K ones are two squares, and 5600K ones are 5. HOWEVER, all GD parts also share this trait (5600K):

ALSO, of ALL the "warm white" parts (2700K, 3000K, 3500K, 4000K, 4500K), none I could find have the 5 square shape. So this would imply the one I got is 4500K and not 5600K. Other than this, I'm not sure this means anything else. All are 1A max, and of course flux bin is not marked.

 

This took quite a bit of time.

 

I would've like some of the 5600K's, but I guess they don't ship them anymore. Oh well.

I beleive that the one with 5 divisions is GDP and the one with 2 divisions is GD (not Plus)

 

It's vice versa, (some) GDs have 5 divs and GDPs have 2. So the ones with 2 are more uptodate and brighter. Smile

OK, the Golden Dragon divisions mystery is solved! (or should be solved now)

Thanks! I was wrong
