Summary

The Nitecore P27iX is a tactical flashlight that impresses with a well-designed user interface and four special "M515S" LEDs. The multi-stage tail buttons provide direct access to four brightness levels, while a sliding switch reliably protects the flashlight against accidental activation. Only the SET button on the head requires some getting used to. Also worth mentioning are the battery level indicators and the USB charging port with its metal flip cover.

The width of the beam can be adjusted in three steps – a useful, though not strictly essential feature. In addition to the four regular brightness levels, there are two particularly bright modes called "Search" and "Lumin Shield". Some of the button assignments can be customized to suit personal preferences.

A major drawback, in my view, is the proprietary battery. A design that works with standard 21700 cells would have been clearly the better option. The NL2155HPi is not only relatively expensive at over $30, but its long-term availability is also not guaranteed.
