How to Choose a Dive Light

Posted by Dive Professional: Will Taylor on on 10th Apr 2023

One of the essential pieces of equipment that the advanced open water class requires is a dive light. A dive light illuminates the underwater environment, allowing divers to see the breathtaking underwater scenery and fascinating marine creatures. However, with numerous dive lights available in the market, choosing the best dive light can be a daunting task. In this article, we will discuss the factors that one should consider when selecting the best dive light for scuba diving.

Light Output

Light output is the most crucial factor to consider when choosing a dive light. The light output of a dive light is measured in lumens. A higher lumens rating indicates a brighter light. However, a bright light does not necessarily mean it is the best choice. Divers must consider the type of diving they intend to do before selecting a dive light. If they are diving in murky waters, they may require a higher lumens rating to cut through the darkness. In contrast, a lower lumens rating may be sufficient for diving in clear water.

Beam Angle

The beam angle of a dive light is another important factor to consider. The beam angle refers to the width of the light beam. A narrow beam angle is ideal for long-distance visibility, while a wide beam angle is suitable for illuminating a broader area. Divers should consider the type of diving they intend to do before selecting a beam angle. For instance, cave divers may require a narrow beam angle to illuminate small crevices, while wreck divers may prefer a wider beam angle to explore large areas.

Battery Life

The battery life of a dive light is another critical factor to consider. A dive light with a long battery life ensures that divers can explore the underwater world for longer periods without worrying about running out of power. However, battery life is dependent on the light output and beam angle. A higher lumens rating and narrower beam angle will require more power, reducing the battery life. Divers should consider the type of diving they intend to do before selecting a dive light with the appropriate battery life.


The price of a dive light is another factor to consider. Dive lights are available in various price ranges, and divers should select a dive light that fits their budget. However, divers should not compromise on quality when selecting a dive light. A high-quality dive light may be more expensive, but it is a worthwhile investment for scuba divers.
