- Material and durability: Constructed from aluminum alloy and plastic, the light is wear resistant and designed for marine use with corrosion resistance. The enclosure is sturdy for demanding environments. - Optics and light distribution: The vacuum electroplated lamp cup reflects the light from a high brightness LED to illuminate a wide area and reach long distances, improving visibility in dark conditions. - Water resistance and diving capability: The lamp and switch are designed to resist water pressure and operate reliably under water, suitable for diving up to 80 meters. - Modes and performance: Features three modes for different needs: high (strong), low (weak), and strobe. This allows you to adapt to varying environments and tasks. - Safety and convenience: Includes a lanyard that can be worn on the wrist to prevent accidental drops and enhance carrying security. Use scenarios: - Night diving or wreck/reef exploration where strong illumination and wide beam reach improve safety and navigation at depths up to 80 meters. - Low-light underwater photography or inspection tasks, where adjustable beam intensity helps balance exposure and conserve battery. - Surface uses such as nighttime camping, boating, or fishing, where reliable lighting and the strobe mode can aid signaling and visibility.
