Ever need a handsfree headlamp to see what you are working on, or where you are going in the dark. We did, so we found a line of handsfree headlamps from Black Diamond. Being LED, they consume minute amounts of power, while being very bright. We use rechargeable NiMH batteries charged with a solar charger, so the electric is clean, and there’s no battery disposal issues (they last for many years in this application). Dharam bought us a Zenix IQ as an early Christmas present, based on his happiness with one of their earlier models. The company website has the following specs:
Smart lighting for the backcountry, the Zenix IQ provides non-fading, constant illumination in two modes: a collimated one-watt LED for a long-range beam, or two SuperBright LEDs for close-range ambient light. A single switch toggles between four settings for each mode—min, mid, max and strobe—and remembers the last setting you used. This lamp also supplies constant illumination and comes with a battery power meter and Find Me light.
