Two questions about the Nitecore: 1) anyone know how easy it is to upgrade? Folks always point out that todays greatest will soon be outdated. 2) Correct me if I am wrong, but I think the Nitecore requires 2 hands to change brighteness - correct? I love my Novatac because after setting the brightness levels, I can easily get the output I want with one hand. I wouldn't want a light where changing output levels requires two hands.
If you unscrew the driver from the head, the emitter is accessible, and just about as easy as any other similar light to swap out (think Ultrafire C3 style swap)
The head can be tight, but if you lube the front o-ring a bit, you can manage with one hand.

But what's the big deal with
occasionally needing two hands? Just a few years ago, the only option was one brightness setting. These days I see a lot of people criticizing lights for occasionally needing two hands to change modes. Seems like a small price to pay for having so much flexibility at your fingertips (literally). As for the NiteCore in particular, I'd much rather have to occasionally use two hands to change the brightness (simple as twisting the head a quarter turn) than constantly clicking the switch to cycle through a bazillion modes EVERY time I want to use the light.
My my, the masses are picky these days.
