For years, I use the "normal" Ixon IQ (ie without premium with "only" 40 lux) and was always very happy. I often go in the dark long distances and was grateful for the good luminous efficiency. From the new Ixon IQ Premium I have promised me anyway much more light. Unfortunately, this request is only partially fulfilled. While the premium radiates the sides much better (the cone is so much wider), but as I do all over Weigend use normal bike paths, I need not really. Unfortunately it does not seem, as hoped, also a lot further. Since they can not get much further than the normal Ixon IQ (which require but also pretty good can). In conclusion, I would say: Who has a functioning normal Ixon IQ, need not necessarily update who newly umsteigt from another Funzel the Ixon, (should be equal access to premium especially those who sometimes likes off driving in the dark of bike paths - Here the wider cone brings really something). Trifle aside: My original charger the Ixon IQ without premium really does not fit into the socket of the new premium. Although the ultimate case appears absolutely identical in comparison of IQ and IQ premium, so I succeed only with violence to push the plug of the previous model in the socket on the new premium. To load therefore I take the batteries back from the lamp and invite them long along with this the closing mechanism of the lamp in an external Ladegerät.Wie remains to be seen. Second bite at the edge: The "remaining power indicator" I did not understand even in the old IQ and do not understand it even with the new premium. Somehow a diode flashes as ever, regardless of whether the batteries are freshly charged or have a couple of hours under his belt. But when regular users I know that about four or five hours to create the four AA batteries to full intensity, then turns off the lamp in the weaker operating down (in the old IQ of 40 to 10 lux with the new IQ premium of 80 to 15 lux in IQ premium). The burn time was even still enough to not stand still in the dark. With the mounting way, I have good experiences. In all these years the old IQ is never flown unktrolliert out of the holder. Da has not changed much on the bracket, which should continue to go well.
