At the last Geocaching Tour a colleague, the lamp was there and was proud as Bolle ... When I showed him my lamps that were only marginally more expensive or sometimes even cheaper, and have all asked the P7 in the shadows him clearly the facial features slipped. (No, I do not mean the grottigen Chinafunzeln a la Xyz Fire) I have looked at the P7.2 during the tour in more detail and therefore draw the following conclusion.
Per
+ Good workmanship of the lamp. Clean thread, everything misses is well in hand.
+ Obviously, good heat dissipation to the housing
Negative
- Operating with 4xAAA batteries. AA batteries offer more than double the capacity and do only slightly more weight / scope with such a torch. Here was definitely saved at the wrong end.
- Only splashproof (well due to the zoom mechanism)
- Only 320 lumens very bad in this price range
- Lamp is not electronically controlled. ie falling brightness with decreasing battery voltage.
Overall, the P7.2 is an interesting concept and per se is not a bad bulb. But it has a number of weaknesses that can not be dismissed out of hand. These are primarily the poor battery choice and nonexistent regulation. The lamp I would therefore awarded 3 stars.
But to a product also belongs clearly the price-performance ratio. Compared to the competition (NiteCore, Fenix, Armytek, Zebralight & Co.) that produce on the same quality level of the P7.2 LED Lenser provides far too little.
Therefore, 1 star for value. One requires here absolute premium prices and offers in the technology only average ... Quasi a VW Polo - which is a good car is beyond doubt - for the price of a Porsche.
So that makes the sum of 2 stars. A good alternative in the same price sector and with standard cells would be a NiteCore Ea41 which is also verabeitet excellent and absolutely in all technical matters better.
