i've been absent for quite some time (about a year) with deployment and a few schools i had to attend, but i just lost my quark123 about a month ago (the original R2 version) non-tactical with a clip, after 2 years, that was by far the best EDC light i have had, there are a lot of other and newer lights out there, but for the form and function that was the best...i used to to teach both my kids to crawl (turn it on low and put it far enough away that they have to move to get there) and they sucked on it a lot, it also went to Iraq with me, i miss it like crazy, perhaps a new one is in my future for Christmas
