Most Astrolux flashlights and parts are out of stock at BG. It seems like they have stopped producing the Astrolux brand. Also, Mateminco who produced Astrolux and also sold them as Mateminco flashlights hasn’t produced a really interesting flashlight since the MF01X.
It is true that many manufacturers have nice single cell flashlights but Astrolux/Mateminco used to have big and powerful flashlights like the MF04S, the MF01S and the MF02. Lumintop has some similar BLF inspired flashlights but at premium prices.
Some Astrolux/Mateminco flashlights had really nice colors and also copper and brass versions. I’m glad I got myself a nice collection as long as they were still available, some of them mainly for the looks 
. I would have loved to see their full brass MF04S (✌ FREEME - ASTROLUX MF04S (XHP70.2) & MF04 (XHP35 HI) - BRASS@.@) and the MF03 with 8x XHP70.2.
