The new NR HID lights with Lithium battery packs have a shorter runtime of about 2.5 hours.
The older NR HID lights used a NiMh battery that, in some packaging, was like two standard halogen battery packs taped together.
The Slick Rock has a 2.5 hour runtime too, but it uses a NiMh battery and also puts out twice as much light (900 lumens).
During the summer there was much better pricing on lights, but now it will costs $300 or more for an older NR HID light, such as the Rage.
