Versatile and easy to handle

The built-in electronics comes with different batteries / accumulators (size AA) deal, from a
weak NiMH battery with 1.0 volts to a Li-ion battery with 3.7 volts.

The power switch is rugged (by pressing on the back and not by twisting of the front part
so that the lamp never turns against the rump in the pocket by itself)

Repeatedly (fast) Pressing the power switch can be equipped with 4 modes:
Off / reduced power / full power / flashing light.

The reduced power is not displayed when illuminating nearby objects and saves battery / battery.
The full power is very bright. The adjustable lens allows a very sharp focused light
and on the other hand a wide gesteutes light, which is very useful at close range.

To use the lamp on the back (like a candle) and thus shed light on the ceiling,
which is very convenient.

The lamp is so good that I have still gained a second of it!
