Another qark user here, brilliant light, great flood, headstraps come loose every time you take it off.
Ability to take AAA batteries is a big plus.
Worth the money.
its just the same as picking a light for mtb night rides ie brighter for faster and/or more technical. i have a Petzl Nao and Silva for night time 'park runs', but these days i run singletrack which requires a brighter light so use an Exposure 1000 head torch
I got an iko core. Very comfortable indeed and an excellent even spread of light.
Qark has arrived, seems mint! Won't be trying it out till the storms are over tho...
I am happy with a petzl Nao for off road running, trails, woods and hills
First run with the Qark last night, it's fantastic!
Another Qark user here
Keep finding myself thinking 'wonder if they do any bike lights this good?'
Have bought one of their cheapest ones for my 7 year old to stop him stealing the Qark all the time!
Hope r4....
But a led lenzer is by pound by pound the daddy
Hope r4? Lol, I won't have a separate battery pack light on my bike never mind my heid!
Lot of our lot round here use them
Lenzers lighter by a long way
petzl iko core is half the weight and double the light of the lenser. bit more expensive though.
