B Dub wrote a review of Black Diamond NightRay Headlamp on February 23, 2007
Pros= Good balance in the engineering. I enjoy the high/low variations of each of the three lightbulb settings. The lensed l.e.d. makes for a nice beam.
Cons= The cord might get snagged on some underbrush. It is also a bit awkward at first. The design is not as simple as other headlamps. Overall, I would still buy it again. It remains my most powerful and cherished headlamp.
