Remember that the astrolux s1 is the same light
You can get the s1 18350 on banggood with code ac18 for like 15 USD with code ac18 and add the 18650 tube for 4 USD
Its a very good seller for em, so i would be surprised if they discontinued all versions of it
In fact the a6/s1 and s41 (same driver and body) is the ONLY astrolux light im willing to buy
As astrolux has NO CS or warranty after then initial purchase period has passed
As evidenced by the various threads here lately on astrolux issues
