Using the Swift RL headlamp is super easy. To turn it on or off, just press the single button. You can also use this button to switch between lighting modes, adjust the brightness, and lock the functions. When you're out at night, the reflective headband will help others see you. During high - intensity activities like mountaineering or running, enjoy the stability provided by its split construction. If you need some red lighting, you can choose the continuous or strobe mode. As for charging, just plug it in, and use the five - level gauge to keep an eye on the battery. When not in use, store it in a dry place. Avoid exposing it to extreme temperatures and water for long periods to keep it working well for a long time.
