However, the Neutron2A v2 also produces in the short, compact version with a battery (without screwed extension) already a so extremely bright beam of light, that this should be enough for most areas of application in the private sector. Alternatively, the flashlight with 1 x 14500er 3.7V Lithium-Ion battery can be fitted. Then you achieved in the short version (without screwed extension) already in about the brightness that they reached with the prolongation and 2 x AA. A configuration with 2 x 14500er lithium-ion batteries is NOT, however, explicitly possible for the lamp is not designed.
Qualitatively, we are dealing with the ThruNite Neutron2A v2 with a quality lamp made of robust, black anodised aluminum. Very noble executed, insofar as the model is likely to appeal to collectors and light purists. Delivery will be made with an optional metal clip for attachment in an unfortunately somewhat cheap version, my only complaint at this point.
The functionality of the lamp is astounding explained simply and quickly: A long press of the OFF state to the soft-button activates the Moonlight mode when times very little light is needed. A step that is needed more often than you think. Simply pressing the button activates the lamp, it switches to the last used brightness (Memo) with three possible levels. A quick double pressure leads to a very bright Turbo mode (perfect with NiMH batteries), but which only a few minutes can be maintained for technical reasons, then switches the Neutron2A v2 back.
The burn time in the different Helligkeitsmodis please refer to the manufacturer's instructions. Again, this ThruNite lamp moves within the usual range of high-power LED flashlights.
* My opinion: For me the Neutron2A v2 is currently the best lamp for AA batteries (NiMH). It combines a low price for the overall performance, with extreme maximum brightness and a very high-quality execution. Therefore, 5 star at this point are perfectly adequate. If you are looking for a flashlight for the battery / battery format AA, you should access here.
In regard to heat generation: Some reviews address the heat generation. To this end, they should know that very small and very bright flashlights are not generally designed for to be permanently operated in the highest levels of brightness. Because due to the compact design there is a problem with the dissipation of the heat at full power. Larger flashlights are in such instances also warm, but they can heat by more aluminum heat sinks usually a better guide. Here of course the current ambient temperature plays a role. Who needs a long time a lot of light, which was to buy a variety of reasons a completely different light, for example, a Fenix TK35 or TK75.
