Have you ever wondered why daytime divers still take dive lights along? Because the deeper you dive, the darker it gets. Whether your expedition is during the night or you’re planning a deep sea daytime adventure, having a good dive light can enhance your comfort level and overall peace of mind.

Needs and preferences vary among divers. For deep sea divers, a huge factor when choosing a dive light is its depth rating. But brightness, beam angle, and the dive light’s power source also come into play when shopping for a deep sea dive light.

Brightness: For deep sea diving, brighter is often better. Look for lights with a minimum of 2000 lumens.

Beam angle: Depending on what you plan to do underwater, you may need a light with a wide flood beam, one with a narrow beam, or both. Wide beams cover wide areas and are better for daytime diving and shallower dives. However, for deep sea and night dives, lights with narrow beam angles are ideal, allowing for more control. Underwater photographers and videographers, as well as commercial divers, typically take both types with them – a wide beam dive light for ambient lighting, and a narrow beam light for task lighting.

Depth Rating: For shallow diving, anything with a depth rating of up to 100 ft will do; but for deep dives, the depth rating needs to be much higher at at least 200ft.

Power source: There are rechargeable and non-rechargeable options on the market. While both are effective, it all boils down to the one that best suits your needs. For frequent divers, rechargeable is better since it saves you money on battery replacement costs.

Having the most appropriate dive light is not only essential for your overall safety, but it can significantly enhance your overall dive experience.
