I just bought a new flashlight for daily use at work, a demo model Surefire U2 Ultra. This thing is the best flashlight I have ever seen, it is definately worth it. I use it at least 1/2 an hour a day on the middle setting and it outperforms my 3D maglite and I haven't had to change the batteries yet in over 2 weeks. Highly Reccommended if you can find a good deal on it.
