4.2 Indicador de nivell de bateria

The tri-color indicator provides a quick visual of the remaining battery life:

  • Blau: > 80% de bateria restant
  • Verd: > 30% de bateria restant
  • Vermell: > 10% de bateria restant
  • Vermell intermitent: Approximately 10 minutes of working time left.

4.3 Modes de funcionament

  • Video Light Mode: Provides a powerful 4000 lumen beam with a 110° angle and 5000K color temperature for general underwater videography.
  • Full Spectrum Color Rendering Mode: Utilizes the COB white light combined with precisely controlled colored light to optimize the color spectrum for enhanced CRI (≥RA95) underwater.
  • LED Flash Function (Strobe Mode): The light can function as an underwater strobe, producing a 5000-lumen flash. It synchronizes with your camera's built-in flash via a fiber optic cable. This mode is fast enough to synchronize with cameras that use a pre-flash. A lower-power setting light can be used before the flash fires to compose the shot.
  • Focusing Light: Can be used as a dedicated focusing light. The 'FOCUS OFF' function triggers synchronously to remove traces of colored focus lights from photos.
  • Auto Color Changing Mode / Artistic Background Light: Offers over 600 kinds of colored lights, creating rich background halo rendering effects for creative shots.
