Using the Baldr S BL flashlight is easy. Just turn it on to enjoy the bright 800 - lumen light. It's perfect for camping, hiking or just walking at night. When it runs out of power, simply recharge it using the built - in charging function. Make sure to keep it away from water as it's not waterproof. Also, don't expose it to extreme temperatures. To maintain its performance, clean the lens regularly with a soft cloth. This will help keep the beam strong and clear.
