as an anti-aircraft headlights ...

This lamp lights up like a handheld spotlight!
In contrast, the size is tiny. However, they both fit well in the hand as well as a trouser pocket.
The end cap can be turned on very well with his thumb.
There is achieved an absolutely good Ausleuchtnug in all modes of the lamp head-focusing, it suits me perfectly.
Even the thought of itself as a Morse function jog mode of Endkappenschalters is convenient in other ways: One can 'sometimes just' light up at short notice, without having to click in the button firmly.

That here the '123' batteries are used, it is first time to get used to (because rare and therefore not used).
Since these lithium batteries but have virtually no self-discharge, this lamp is also after a long period of inactivity time still operational.

I still only 4 stars awarded, has to do with that person but I lack an ECO mode, so a 'braked' with a luminosity. That would probably extend the burn time but significantly.
To illuminate the walk times or to find the keyhole, this is normal (and only) light mode not necessary that strength.

In the enclosed mini-description gives the impression that you would 2 light modes. Probably there is a leaflet with standard 08/15 Text for all models of this manufacturer.

Addendum: Today (10/07/2010) night about 3:00 I have after the storm from my balcony on the 1st floor (5m high) hinuntergeleuchtet in the yard, to detect any changes.
The lamp lights up a corner of the yard (ca. 90 m²) completely. At each corner of the court such a lamp, and would 'daylight' illuminated.
It is impressive!
As one of the previous reviewers mentioned: Due to the long shelf-life, or Selbstentladedauer, the batteries will this mean 'take-along' lantern.
