What type of lighting is often necessary during wreck dives?

Artificial lights are often necessary during wreck dives due to the typically dark and confined environments found within wrecks. Wrecks can be submerged at significant depths or be situated in areas where natural sunlight does not penetrate effectively. Consequently, divers rely on artificial lighting to illuminate dark passages, compartments, and other areas of the wreck to ensure safety and enhance visibility.

Using artificial lights allows divers to thoroughly explore the interior and identify hazards, while also observing marine life that may inhabit the wreck. This enhanced visibility is crucial for navigation and helps divers avoid potential dangers such as entanglement or getting lost in complex structures.

Natural sunlight may be available in shallow parts of a wreck but is highly insufficient for deeper explorations or areas that are significantly enclosed. Fluorescent lights, while potentially visually appealing, do not serve the primary purpose of increasing visibility in darker environments. Infrared lights are not practical for general diving purposes, as they are not visible to the human eye and require specialized equipment to be useful. Thus, artificial lights are essential for a safe and effective wreck diving experience.
