The SBT90 Gen2, GEN1, and SST90, how tell them apart?

LED Flashlights – General Info

I was searching to buy an SBT90 gen2 in 6500k, in addition to doing some home work on differentiating them. I have been on the manufacturers website and read all the data sheets but still can not tell them apart. I saw a few SBT 90 for sale on digikey but cant tell if they are gen2 or gen1. How can one tell, please chime in, thank you?

You already know this, just clarifying it.
Some guys here have purchased some from China, maybe they can explain how.

If you are willing to pay then wait 6-10 weeks they will put them on any size board you like. Just just finished bagging mine.
