Dear Mr. Petrof,
Thank you for contacting Mouser Electronics.
I believe you are interest to datecode information on the LED’s. Date code I cannot check for exact date code, but you could specify hoe old date code do you need. We could offer date code not older then 1 year, 2 years, 5 years. All of the part numbers mentioned below are fairly new products for Mouser and they are all identified as a cool white.
If you have any further questions, please, contact me.
Date codes? FTW? I mailed several times afterthat but i never got any reply, the last email was with pictures included exacly for what to look for 
Well…. i know we( the world) are in the middle of a crysis ( again) but lately Mouser pesronel is…more or less ” incompetent”…i have better support from Gearbest( for instance) or most of our flashlight providers
O.T
Yes, Mouser isnt a budget company, yet their support is quite budget i guess
