Damn, that sucks!
What sort of light are you after? The standout feature of the Quarks for me is the really low low, which is great for the recreational trespasser.
Some thoughts:
- should it fit easily into a pocket?
- does it need to be super bright, or just really bright?
- for lithiums, 18650 or RCR batteries? or something else again?
- is runtime an issue, or is swapping batteries fine?
- any budget in mind?
