How to use

Usage recommendations

For best performance, check battery status before extended use, clean the lens and housing to maintain light output, and avoid submerging the lamp to preserve water-resistant seals. When performing close-up work, use lower brightness to reduce glare and extend runtime; for navigation or search tasks, select a higher-intensity focused beam.
