I see the B&M Ixon IQ is in the big list, but bike24 is cheaper than dotbike. Mine worked out at £54.37 including shipping. I gather it is not as bright as the Hope Vision 1*, but does have a run time of 5 hours on full power and is a very well designed piece of kit (integral battery holder, proper reflector design putting a nice big patch of light on the road, doesn't just shut off when batteries can no longer provide full power output). I'm using in on unlit and unmarked country lanes. The only time it feels a bit lacking is on soaking wet black tarmac when I still have to play a spot of "guess where the potholes are".
The Lumotec IQ Fly is the dynamo equivalent to the Ixon IQ.
