Ordered by Busch & Müller me this lamp and the combo set "IXON Core + IXXI". In a direct comparison is simply the considerably lower weight and the dimensions of B & M Ixon core (about half the size), with comparable light output to better remarkable. The fluorescent image of the sample images of RX5 I can not confirm, in particular, not even illumination. This also makes the B & M better what you can well judge if you have both a direct comparison. Opening the RX5 purpose battery removal is not really comfortable, also because the B & M stands with the simple charging of Li-Ion batteries via USB charger. Finally, the B & M Set incl. Rear light costs about as much as the headlights alone. The assessment in the other reviews are in principle indeed correct if I do not quite understand the euphoria. We must halt the IXON Core not hold on an ancillary (which also still has potential for improvement). The pity is that here the return costs are to be borne. Other dealers remain despite legislative change in customer-friendly variant. One must stop to know and I did not know, because at the time of my purchase, the revocation information were not stored here. Now they are there ...
