Troubleshooting

  • Light not turning on: Ensure the battery is charged. If operating via USB-C, confirm the cable is securely connected and the power source is active.
  • Short battery life: Battery life can vary based on brightness mode. High brightness consumes more power. Ensure the light is fully charged before use.
  • Light not charging: Check the USB-C cable and power adapter. Ensure the light is turned off for optimal charging.
  • Light output reduced when plugged in: This is normal behavior for continuous operation. The light operates at a reduced level to prevent overcharging and allow for continuous use.
