fwiw, I have the Thrunite Titanium also, I dont like to use it because the threads are so gritty, but it is my brightest aaa. I prefer to use my Copper Maratac, the threads are much better, and its pretty bright too.
I like bright little Cool White AAA lights, even though they are low CRI, part of the time. Other times I prefer High CRI Neutral White Nichia 219 LEDs. And I have a love of Copper, though its heavy, I like that its Oligodynamic.
