In reply to mikeericknd:
I have a LedLenser SEO 7R. Love it to bits. I use it for running and climbing. Good points:
- rechargable battery or 3 x AAA
- good battery life
- range of brightnesses, including high, low, flashing
- focusable beam (really useful when running)
- superb customer service. After a couple of years it stopped working for no apparent reason. I contacted LedLenser, they said "send it back", and they replaced it (free) with a new one. No quibbles, no hassle.
By contrast, I have also used my wife's Petzl Nao. I find it too heavy, and the "intelligent beam strength" thing just weird and annoying!
