Can someone explain how this apparently impossible feat is made possible just by lining up more 18650 batteries behind an XM-L???

........ or Dundee lumens (ie: That's not a torch, THIS is a torch!)
"These XM-L chips are well capable of being driven harder for higher output - if you check the performance curves provided by Cree - very straight almost linear increase in light output with increasing current and voltage. Although rated to 10W@3000mA/3.3V, with a higher voltage power supply, the factory's R&D department says these LEDs can go to 30W with light output remaining close to 100lumen per watt."
