OSRAM confusing part number - JTLMS1.CM

I am looking at GW JTLMS1.CM part from OSRAM

One part example is GW JTLMS1.CM-G8H2-XX56-1-60-R33. Especially the “G8H2-XX” part. How shall I decode G8H2 when G8 and H2 each are different brightness group mentioned in the datasheet? Will the forward voltage number like L1 will replace the ‘XX’ portion?

Thank you,

Hello centylab,
Welcome to the TechForum, at present I have a link to the application notes from the manufacturer site.
OSRAM DURIS™ E 2835, GW JTLMS1.CM White LEDs | ams OSRAM

Hi wonder if you can get us some more info. The info is not yet enough for us to make good a design.

Hello,
Page 3 of the datasheet has the ordering information you would order by color temperature, the XX is just a place holder for the manufacturer or internal for the manufacturer it gives no explanation and has the ordering code for the part.
