I had for 2 years the B + M IXON IQ on the wheel. Your light output is comparable to the MacTronic roughly. Here initially earn both lamps a 1! Thus, if both lamps Toll ??? Answer: A very clear NO. ... The MacTronic loses clearly by KO! The reason: the practicality of MacTronic the bicycle is very limited. First there is the fact that the initially very bright light MacTronic quickly darker and darker. There is no electron. Control as in the IXON holding the level of brightness for a long time constant. A clear disadvantage. Furthermore, the MacTronic draws its energy from 3 AAA (Micro) batteries. Compared to IXON with its 4 AA (Mignon) it soon becomes clear: The MacTronic goes quickly run out of steam. And also annoying: the exchange / replacement of the batteries / rechargeable batteries becomes quite cumbersome when MacTronic by the small screws and the battery box. Unfortunately, you have but just this process very often repeat. The annoying after the first week enormous! (The IXON hingegenverrichtet even after 3-4 weeks even their service reliably without shuffling marathon). For me will end up being Fazt: The MacTronic is a very bright flashlight for short Notsituatonen. The daily and persistent companion by bike unfortunately not right.
