Agh, anyone understand Digikeys 'binning'? Or, are there really R2-5A XRE's?

Are there indeed Warm/Neutral white R2-R4 XRE's? Read below.

Optimistically, it looks like Digikey carries XR-E R2's in warm white, etc. but I know I must be reading their binning wrong.

I'm trying to find out what brightness bin their neutral/warms fall under. Specifically looking at their 4,000K LED (Equivalent to a 5A). Since Cree hasn't decided to update their binning charts in 2 years, I have no idea what to believe. The R2 also could mean "Tinting towards red"

The luminous flux numbers are all over the place for the stuff they have too, even tho all of it has "R2" in the name. This 4000K one has luminous flux that would be in the R2-R4 range if it were rated at 350ma (Which is how cree rates it).

Here's the digikey LED in question:

Since their websearch can't be shared by URL, I'll refer to the PDF page of all their cree leds, it's towards the bottom:

The kit code 009E5 corresponds to P4 bin and 5A, 5B, 5C and 5D tints according to the datasheet. The R2 in the product name is just an internal code, again according to the datasheet. It IS strange why Digikey lists 137lm as the luminous flux though... unless it's the luminous flux at 700ma?

Rog-o, thanks. It all makes sense now. Arrow and Digikey don't seem to have any R2's
