FYI - expect these leftover BT21’s to be the degraded quality ones and not the great ones produced during the first batch. Still good, but not the great light it was. Love my original one with 10° optics and aluminum GoPro mount!

It looks like you got more replies and NO offense was taken by me.—-I just wanted to understand your use of the :person_facepalming: —-Guess what ?! I still can’t
figure out what the joke could be . You said it’s like a old friends thing , so no offense to me.

That’s one cultural interpretation.
Your culture may differ.
I think the :person_facepalming: is due to the fact that Revtronic can’t make the bt21 with good quality and they have given up on this light (which is a bad business move imo). Driver issues inferior parts. But if you have a good one, the bt21 kicks butt and can punch way above its price!
