Trailrunner, there's also the Zebralight H30. Same as the H50 except:
- less floody beam
- push button instead of twist (so, one handed function) (and comes with a glow-in-the-dark replacement button)
- recessed lense (so no light in your eyes)
- tighter headband bracket
- lanyard ring
The only problem is that it takes CR123 batteries instead of AA. To me, that is the only thing that makes this not the perfect light.

Another great thing about the Zebralights is the power levels of the low, med and high settings.
- Low is good for tasks at 5% of high power
- Med is good for in camp stuff at 25% of high
Having a medium setting at a higher level of power is wasteful.

They are regulated, bright, light, waterproof, multi-mode. And they have an advantage over traditional handheld lights that need side-mounted headbands in that the light is oriented more to the center of your vision and your head isn't in the way of part of the beam.
