I used this LED Lenser SEO3 Headlamp from everything like seeing when I’m BBQ’ing at night to when I had to run wire in the attic. This lightweight headlamp that doesn’t compromise on functionality. LED Lenser’s SEO3 features Smart Light Technology for switching quickly between high and low power and a signal mode. It boasts three white LEDs and one red LED housed in a swiveling head for flexibility. A helpful carabiner clip allows for carrying on the go.
