From Black Diamond:
For placing gear at your fingertips or route-finding from a distance, the Spot is our lightest weight headlamp offering a beam. Housed in a reflector, the one-watt LED throws a far-reaching beam. When all you need is close-range light, switch modes and use the three SuperBright LEDs which emit usable light for over 100 hours. A single switch on top lets you choose from four lighting levels for both modes—min, mid, max and strobe—to tailor the light output to your needs.
Why a lights - headlamps group AND a headlamp group?
