Check out the Tomahawk offering from First Light. I took this L-shaped light as my only pocket option on a 6 week road trip and I'm now hooked. There are a variety of options, including low-power, colored LEDs and strobe.

It takes some getting used to at first, but I definitely found the change from a small tube light to be easy enough.
