Ixon IQ Speed is new Cree XR-E Based lamp (there is Rebel version too), using profiled mirror technology to achieve focusing almost all of the light into usable beam - it don’t shine top of the trees .



Bar mount is universal (Standard & OS) and you can easily change the head angle, to center the beam in front of the bike.

Thermal design :
Plastic case... no thermal design

Some data – maximal values in 1 m :
High - 2270 lux
Low - 370 lux

Power supply :
5 cell 18670 NiMH – 6V 4,1 Ah
340 g (connectors, and holster included)
Quite impressive fast charger 1A output.

The battery-pack mounting strap is long enough to mount battery pack on stem or frame. I think that the stem will be preferable - the connection wire is to short to i.e. put battery pack into bottle cage or saddle bag.

Costs :
About 150 euro in EU so about 200$.
