Black Diamond Storm. I also have two different zebras. The H52 and the H600 (cant remember the specific model). I do carry the 600, but keep it in the pack typically. The Storm is my favorite headlamp because it has capability for dim light, a simple tap to go back and forth from Max brightness to your adjustable dim setting. It also has a red, green, and blue light. Lastly, it has the lock out function. Its become my favorite headlamp. Oh, also forgot to mention....it has two different white lights. One is for distance, and the second is more of a flood light. Great for camp chores, etc. IN the end, I end up carrying 3 headlamps. H600 stays in the pack unless its needed for finding an animal, or other headlamp fails. Main headlamp is the BD storm Emergency headlamp is the Petzl E-light which is in my bino harnesss.
