I'm wondering if anyone makes an infinitely adjustable (like Sunwayman V10R or Nitecore IFE) 1xAAA or 2xAAA flashlight?
...That said, squeezing that kind of functionality into a AAA light without compromising reliability or appreciably affecting the size of the light is a monumental feat and QTC is currently the only way to do it (that I know of). The QTC Eiger is fantastic and it will serve you well.
... and Efficiency! Worst thing about infinitely variable ring lights is that they'll consume more power than the LED itself at low lumen levels.
On the other hand, I wonder how durable the QTC material is. I've read a few post here that the owner(?) had put the light through a thousand compression cycles without any wear.... but a thousand is nothing (max 10x a day for 3-4 months). Do they sell replacement pills?
