Sorry for being a complete noob here, but what is the difference between the CW and NW version of the LED? Is it worth the $2 upgrade to get NW? Guessing color balance?
CW can be very white, especially if you don't see any other light source to compare it, or don't own many flashlights.
Also NW can be slightly cream or orange, but not necessarily.
NW don't give less lumen if the efficiency bin is the same, eg XM-L T6 1A (CW), XM-L T6 3C (NW). However visually, bluish lights tend to look brighter.
Exactly my disposition on flashlight choice. Anymore now I tend to favor AA/14500 because of versatility. Too bad the common step up from AA is C size, and that's just not too practical for the common flashlight.
Also, the new Sunwayman V10A. It's expensive, but it can run on high with a 14500 without overheating, and it has infinitely variable brightness control.
