I agree with Leathel, the DX lamps cannot be beaten for price. I used to be a Lenser fan but these DX lights are almost as good in quality (I'm hard on my headlamps) but beat them hands down in the light and price department. Just remember you'll need some 18650 batteries and a charger as well if you buy from DX. Even with those as well you'll be paying less than a 3rd of a Lenser.
I have 2 of these on the way:
Cree XR-E Q5 180LM 3-Mode Headlamp - Champagne (2 x 18650) - Worldwide Free Shipping - DX
I chose them because they'll take 2x batteries, I found swapping out the single battery on my other one to be a pain in the ass. Not that I had to swap it often but I'm really lazy :XD:
