A full charge typically takes approximately 9 hours.
6. Maintenance and Care
- Cleaning: Wipe the light with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the light in a cool, dry place away from direct sunlight. If storing for extended periods, ensure it is charged every three months.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on | Battery is depleted | Charge the light fully. |
| Light turns off unexpectedly | Low battery; Overheating | Recharge the light. If overheating, turn off and allow to cool before resuming use. |
