The Pava I could close the same to the heart because of their size, weight, compactness and fast assembly / disassembly. However, the illumination is not comparable to expensive helmet lamps, but is okay. The light cone also covers border areas of the path and is sufficiently bright. The weaknesses of the lamp is the fast voltage drop in the high power mode and the somewhat stiff mounting. Especially in terms of price / performance ratio makes the Radleuchte but overall an almost perfect impression, if you're traveling at night on wide paths and no extreme downhill runs.
Buying criteria were mainly the usefulness in everyday operation with me. With me so trips to work on roads, forest roads, and it could be trails. The lantern must be so handy, small, lightweight, removable and robust. It should also be neat long light and you have to be seen. The absolute luminosity is not as important, but a weak Funzel should therefore not be currently in demand.
Specifically I emphasize that I need neither floodlights for night extreme downhills perennial favorite for 24-hour race.
In practice, the lamp did quite well. It has approximately 10m distance sufficient luminous effect. Both in the width and in the distance At 20m you can still recognize much. At faster descents (approx> 30kmh) of course one wishes for a better distance vision in order to detect obstacles at an early stage. Here are clearly the limits of Pava. Due to the principle that mount on the handlebar when cornering singletrack is insufficient because the light cone principle should follow the driver's eye there and not the steering angle (a helmet lamp would be announced here). In broad forest paths and asphalt which is however not an issue.
In high power mode, you can fast voltage drop about an hour with normal alkaline batteries, and NiMh batteries notice after about 2 hours (in the Low Power Mode "has at least three times longer light). The indicator light on the switch will jump almost immediately to red and the Pava is increasingly losing its brightness. you then peels on the Low Power Mode, but the lamp is strangely then bright again. I think that would Sigma can solve better with an appropriate electronics, automatically which eg Low Battery on low down regulates.
The light image by the way - some getting used to - split in two. A bright beam of light down, then a dark stripe and in the distance a weaker beam. Whether this is related to the roadworthiness approval?
The attachment is Sigma-typical with ratchet fastener. Fits virtually all standard handlebars, except perhaps on very curved specimens (eg Hollandräder :-). Quickly assembled / disassembled and at most mediocre vibrators (potholes etc.) nothing happens. However, the dismantling takes place only with considerable effort. In my copy of Pava the ratchet locks so a bombproof on the handlebars, that sometimes I have to take tool to help ...
After about 6 months (winter) operation turned out to an odd electronic defect and the Pava went to exchange back to the dealer. The batteries or batteries were empty within a short time, even if the lamp was turned off. This has been particularly ärgelich, because, surprisingly standing with freshly charged batteries the day before at the evening drive home in the dark. The error happened with different battery or rechargeable battery types. The vice exchange new bulb works so far no problem though.
