After experimenting with different direct drive solutions and resistance mods in my SST-90 4500K torch, I noticed that even when the emitter has cooled down, it now draws more current at the same Vf than it did when first assembled. It's now possible for me to get 9A+ draw from 3 NiMH C cells. Even more after it has heated up.
I made a video demonstrating the current draw now that the emitter has been burned-in:

///___In it, I explain and demonstrate how & why my tailcap current measurements are so high compared to the results that others get.//////
///___I also demonstrate the lower current draw measured using the method most others are using.______________________________//////
By the way, the SST-90 4500K mounted with Arctic Silver Thermal Adhesive in the Brightlumens Deluxe Mag D heatsink starts to turn blue around 13A current draw, in case anyone was wondering.
