Yeah m8, i got my hands of a S4 1A roll, i also got some S4 1D with even better hunting tint yet i do keep them for special occasions

Hi Mitko, is there a way to recognise this old good XPG2 S4 1A leds from new one that have worse performances than old leds?

Yes, take a look at this thread: Cree changed production process for XP-G2 emitters!

The old ones have 40 clearly visible dots on the die, new ones have more.
