In reply to Removed Useralastairmac1:
I use an alpkit qark for running. It was almost the only bright head torch I could find that wasn't entirely reliant on a rechargeable battery. It's good value, very bright and the fact that it takes either AAA or the rechargeable battery is important for me as I know I won't always be able to recharge the battery before I need the torch (either because of location or because I want to do something in the dark at short notice and therefore haven't charged it).
It charges fairly fast and is bright enough for night navigation. Fairly lightweight and comfortable.
The only minus point for me is that it's a bit prone to switching itself on in my bag. But I prevent that by just carrying the battery separately.
