@chefisaac. I've been using the
Gemini Titan for about a year now. I had a battery issue early, but it was replaced on the spot (bought it from a LBS). Thing is crazy bright, and now that it's been discounted, it's a great deal. It mounts securely on my helmet, and a keep the battery pack in my backpack. My winter was on the west coast (think wet but not cold), so time will tell how it will handle colder temps.
