aaa ligths suck
Its junk,
and for this price You might have also gotten a Fenix, and by now a Fenix with a Cree (Model with "...-CE")
--> no HAIII finish on body
--> 3 AAA - no chance the Lux V runs even on half
--> it surely is no Lux V
--> direct drive
anyway, the Lux V have never been a good idea in handheld applications (heat generated and power consumption) and actual led (read: Cree) are much better while running cooler, needing less energy and less voltage, but giving more light.
Any other questions?
best options:
get a Fenix with a Cree, or (cheaper): Get a Fenix with a Luxeon for less
