The Nite-Ize clips aren't exactly the most secure. I wouldn't trust one with anything important attached to it.
Yeah, the Nite-Ize clips, aka S-Biners, aren't too secure as the spring tension is very light on the clip, and the retractable lanyard you are using is not as strong as... say, a heavy duty steel wire lanyard, which is a bit more bulky but a lot stronger. I would change the s-biner to something a lot more secure, with a higher spring tension or a locking mechanism of some type. That setup is good for a single AA, single CR123, or AAA light, but not something I would use for the larger lights.
If you got into a really bad situation and needed to use the light in self defense you could just throw the light at the bad guy and it would come right back to you. Rinse repeat. (this is provided you have enough line/cord/cable to reach said bad guy) It would be look really silly to throw the light only to have it come up a foot short from hitting the bad guy.![]()
for a much lighter light it should be fine, the LX2 is too heavy for the retractable lanyard. :ironic:
