I just browsed Olightworld.com - not a single AA light in sight. Only the recent i5t found, marked as discontinued… does this mean new models coming, or… doom for AA lights?
They just released the i5T some months ago!
AA only light 
And did you see if it was any particular host (copper, desert tan, gun metal)?
These versions are discontinued:

The difference between the two black i5t is the discontinued one has the blue accents on the body and black clip. The non-discontinued one has no body accents but blue clip.
I always liked the S1A. You can still find a used one once in a while. Even the aluminum ones aren’t exactly cheap though. Had a copper one. Very nice but heavy. They are fetching high prices now days.
The I5T does not tail stand? 
Ok… so not everything Olight AA is discontinued. Good to know.
I’ve been eyeing on the S1A for a long time, and it just dawned on me that I can’t buy one anymore. This is kinda why I made this post. Oh well, it’s not like I’m going to run out of lights anytime soon 
For sure. If I still had one I’d send it your way. If I find a smoking good deal on one I will do the same.
AliExpress used to have a store where those were sold.
I would tell you guys to check this post and contact the member wilkins1kc
Just Don’t ask for an extra O-ring . They don’t have any .
Yep, I contacted with Olight and it's really sad to know S1A is discontinued. And now they don't have anything similar. Actually they are still some seller who have stock here in China, but few offer them at a reasonable price
