I decided to heed the collective advice of B&B today (and take advantage of a smokin' deal) and bought a Surefire Minimus Vision headlamp as my first 'real' headlamp. It'll take a little while to get to me, but I'm looking forward to it. I decided on the Surefire for several reasons:
1. I wanted a headlamp that would take CR123 batteries. I keep them for my flashlights and find them vastly superior to the normal AA/AAA sizes. There are only a handful of headlamps that take 123s. Surefire, Zebralight and a couple Princeton Tec models were all that I could find.
2. I really liked the idea of having a potentiometer adjustment instead of a push button, allowing you to get exactly the right amount of light for the situation.
3. I did some reading on 'warm' or 'high-CRI' LEDs and decided that it sounded superior to regular, 'cool blue' LEDs for most times when I would be using a headlamp.
4. Most of all the awesome deal.
