Another work light with weird circuitry (with schematic)

I've looked at a few of these before and they all seem to have some weird circuitry twist. This one initially looked almost identical to the blue Aldi unit, but the circuitry has some weird bits that are actually quite clever.
What's not clever is the current the LEDs are being run at. With a freshly charged battery the current draw was:-
High (2 LEDs lit) 3.8A - 11W
Medium (1 LED lit) 3A - 9W
Low (other LED lit) 1.6A - 4.8W
When the zero-ohm links are removed and replaced with one of the 1 ohm resistors the current drops to:-
Both LEDs lit:- 1.75A - 5.25W
One LED lit:- 1A - 3W
The light output is still very useful, but the light runs much cooler and has a considerably higher run time on a charge. That makes it better suited as a rechargeable light source during these turbulent times.
