The Princeton Tec SYNC headlamp has a sturdy asymmetrical single-arm mount, with a user-friendly interface and simple operation. The synchronization allows direct access to a red LED, a spot beam and floodlight by turning a dial. When maximum power is required, a further turn of the dial activates the dual beam mode - spot and floodlight simultaneously. A lock function prevents accidental switching on during transport and when the lamp is not in use.
