Characteristics:
- Shines up about 15 - 30 m, so quite bright,
- Power requirements measured roughly 75-95 mA (battery - battery)
- Light cone diameter / distance about 0.5,
- Weight with battery approx 70 gr.
- Diameter / Length approx 25 mm / 90 mm.
The processing has a number of weaknesses. So I had wrong turn in a copy of a contact spring, so when you insert the battery pack does not cause a short circuit. In another instance just this contact spring seems to be held by invisible Zinnresten, the actual solder joint can not be seen. The lights still function properly and to my complete satisfaction. However, the lamp has been in use for only two weeks.
The shelf life of the lamps is probably determined by the electrical conductivity of the solder-aluminum press connection. Flashlights with plastic housing may be mechanically less robust, but electrically uncomplicated.
Because of the described vulnerabilities actually four stars, given the price but he prefers five.
