It is operated with only P5.2 one AA battery and is thus light up according to the manufacturer up to 5 hours. The lamp is not regulated, which means that the full light intensity is only in the first few minutes are available and decreases with decreasing battery capacity. Fortunately, there is the necessary AA battery yes practically on every corner in 4 or 8-packs, which one has at hand a decent luminosity Reserve and many hours.
I use the lamp and professionally and am absolutely satisfied. Especially the possibility to focus very quickly and is convenient both under floodlights as well as the high-beam lamp provides a clean photograph. Who still remembers the older lamps of LED Lenser, certainly has the "rings" in mind, which could be seen at the floodlit within the circle of light. This is followed, the manufacturer has now filed something, so there is the floodlit no more rings in the middle and you have a clean photograph.
Included is a holster that is processed very robust and super in my opinion. Thus, you can see the light at any time giffbereit clipped on a belt, or simply keep in the holster to protect against damage or scratches.
Conclusion:
The P5.2 is just like the previous P5 a small practical lamp whose brightness Given ihrere size and the fact that it runs with only one AA battery absolutely thrilled. Compared to its predecessor, the manufacturer has improved the light output properly, so this little lamp is now even more effective. I can recommend the P5.2 and would buy again at any time.
