Perfect! 540

One AAA battery, and you have light! The handling you have once Duch read and understand, but after that it's easy. What a massive big advantage is still: The on / off is a real, physical separation of the battery: it is * not * run unnotwendige circuits with minimal, but still existing power consumption, even from being made.

The brightness in minimum mode is exactly optimal to be no effect to stop once the sleep of the child in the baby room (One does not simply wake a baby ...). In media, it is sufficient to find what in a smaller space, and in maximum mode you can move with it outdoors.

Of course it is not a 1200 lumens part with high-end batteries, but for your pocket / Schluesselbund / backpack it is perfect! I'll probably buy those things even as a gift for acquaintances / relatives.
