and, while a quite outdated light for the tech that is out now, I like it. The new Maglite gives my Surefire a run for it's money but the Surefire looks easily 10 times better in every way (Yes, my Zippo is cooler than yours, no it's not for sale).
I've gotten about a 20 minute runtime before the cells are drained and the light shuts off (always at the most inopportune times too...). The G2 sits at around 5.1 inches with a 1.25 inch bezel diameter. Weight is 4.1 oz with the batteries, which, by the way, are 2 CR123's.
