For the operation you have to previously 4 piece Li-ion batteries of the type procure 18650. I have bought this 4 piece 3100mAh batteries Foxnovo. With batteries of such capacity has many hours of light. Since 4 Li-ion batteries are switched simultaneously, I recommend the use of protected batteries! In length to the battery slot of the flashlight can accommodate protected battery problems.
The lamp is installed in the lampshade 3x XM-L T6 LEDs, which are firmly focused (no rotating ring to adjust the focus). The 3 LEDs are therefore bundled into a beam of light, making the torch a classic "Thrower" is. The lamp has 3 levels of brightness and 2 Special modes are switched as follows:
1. Click: maximum brightness
2. Click: medium brightness
3. Click to expand the low brightness
1. Press and hold long: Strobo Light
2. Press and hold long: SOS flashing
Leistungstechnisch the lamp is in midfield. It is significantly brighter than most smaller Led Funzeln, the 200 Euro Monsterflutern it is inferior but of course. For the vast majority of applications in the home, garden, holiday, the brightness is more than adequate to the brightest level. In particular, who is the first time an LED flashlight is purchased be amazed at how bright these have now become.
Price / performance Technically, it is of course a blast, so I forgive also 5 star.
