Smallest very-high-luminosity 18650 floodlight torch? (say 3-6 batteries)

Flasky, the Astrolux MF01 ( Pre production sample [Review] Astrolux MF-01 4x18650 flashlight supplied by Banggood , https://www.banggood.com/Astrolux-MF-01-18x-XP-G3Nichia-219C-12000LM-Super-Bright-LED-Flashlight-18650-p-1165131.html ) looks interesting indeed!

I have a question, how is the number of LED:s correlated with lumen output (given the same 4x18650 battery set as input)?

(This Astrolux MF01 is rated 12000LM and has 18 LED:s. The Acebeam X80 has 12x emitters, and is rated as 25000 lumen.)

The Acebeam has a way higher pricepoint, and is more lightweight. I think overall the Acebeam seems like a way better lamp.

The biggest limit on the Acebeam (as well as Astrolux) would be that it has only flood mode and no focused long-reach omde.

Do you know any addon lenses I could use to give long distance mode?
