Reasonably bright, lightweight and good power management - Black Diamond 200 Lumen Cosmo Headlamp

First off I know this isn't the brightest headlamp in the world, it's listed as 200 lumens, I think the BD Storm is 400. That being said the Cosmo met or exceeded my expectations.

I broke this in on a backpacking trip to Los Padres National Forest. We got a late start and had about 2 miles of night hiking to get to the campsite, I had no problems navigating the trail which was overgrown in many places. We arrived in camp around 10PM and I stayed up until about midnight using the light in low mode which isn't too blinding for your campmates. When I woke up in the morning I found that my headlamp was on, I'm assuming all night. It still had plenty of power for the rest of the trip although it seemed like it would auto dim to save power. I even had enough juice to use it car camping the next weekend. I recommend the Cosmo, it's served me well.
