Endeavour
Flashlight Enthusiast
Karl: Only Titanium this time around. (But I promise to remember your name this time! )
matrixshaman: Point taken, though I don't anticipate doing an aluminum run, unfortunately.
cryhavok: No - I considered using higher currents but opted instead for greater runtime and less heat; the Nautilus is a rather small package and made in Titanium; Practicality, inclusive of thermal management, was an important consideration. 107 lumens is a lot of light in and of it's own right - I'm sure you'll agree when you see it in person.
jch79: I don't design rechargeable cells - the cause of the short runtime is the extremely low capacity of a rechargeable CR2 battery of only 350mAH, not the flashlight itself. The Nautilus, like the Ion, drains the cells down to nearly bone dry, and regulates to much lower voltages than most other drivers I've ever seen - that's why I use such a design. Direct drive off any battery or only pseudo-regulation might give you longer runtimes, but it won't give you constant light output.
With the runtime you'll be getting on the Nautilus battery changes will be few and far between when using primary cells - a pack of 10 cells would likely last me over a year. Of course, your mileage may vary according to usage!
That said, the light will run off RCR123s. As I always, I don't recommend their use because of the dangers inherent with rechargeable lithium technology - there have been several documented incidents here at the CPF of batteries exploding and causing a good bit of damage to property and people. Is the light physically capable of using the cells? Yes - it'll function the same way the Ion did, low mode being brighter using the cells than off primaries. Is it recommended to use those cells? No.
Charles: DM51's response was pretty much spot on - the beam is very smooth and the reflector has a light orange peel texture to ensure that; The pictures show the beams of all the lights accurately.
Take care folks!
