Dive light depth ratings are used as a primary parameter in measuring the equipment’s capability to operate under the ocean. Dive lights are significant in giving visibility to the divers during their night dive or whenever they visit underwater caves, cenotes, and dark waters.

Considering the water absorbs light the deeper you go, it is difficult to see underwater. Divers use depth ratings to measure the safety of their equipment and how far it’ll withstand the current and the pressure of the underwater environment. Also, depth ratings for dive lights vary depending on the brand and the quality of dive lights you use.

For example, there are dive lights such as the ScubaPro Nova 230 Dive Light that has a depth rating of 120m/390 ft. This means the product can withstand the pressure of the said depth without flooding the light itself and damaging its batteries. Divers must decide which dive light to purchase based on their diving skills and habits. Normally, deep divers go for a dive for more than a hundred feet so they need more expensive dive lights that can cater to their depth ratings as a diver. Meanwhile, recreational drivers find it more comfortable to look for a dive light that works between 0 to 90 feet.

No matter what, depth rating must be closely considered to avoid dangerous encounters in the ocean due to malfunctioning equipment. Light is important and if a diver chooses a dive light that is not depth-rated and compatible for his/her own dive depth, the pressure would cause leaks or flooding, resulting in the batteries and the light’s internal composition being damaged by the water. Also, the dive light might face breakage and other malfunctions that will cause divers to not being able to see in the dark depths of the ocean.
