well you want a light than can be carried on your belt, right? Can you be a little more specific?
- Does it need to be bright?
- Do you want long run time?
- What kinds of batteries do you prefer?
- Whats your budget?
- What size?
- Do you want a simpel light which goes on/off or do you want something that has selectible brightless, SOS, strove, etc function?
- Waterproof or water resistance?
here is a great website with many reviews:
http://www.flashlightreviews.com/Mine belt carry light is either a Fenix L1P or a Nuwai Q3. Which are reasonably bright, yet small and not to expensive. I prefer the Fenix, due to the battery type it uses, a more exsecutive style look and much better supplied sheath. Both are availible on the web.
