Lights to see by are much more expensive than lights to be seen by. If the path is pitch black then you can get away with dimmer lights than if distant lights spoil your night vision.
Batteries can add a lot to the cost so you need to work out the runtime required, I saved money by getting a light that takes AAs. I'd look for a P7 Lenser based torch that takes AA, AAA or CR123 cells.
I've got a Cree Q5 LED which is adequate but I'd go for something brighter next time, the P7 may have been superceded now as development is fast in this market.
