How to Choose a Diving Light?

Choosing diving lights is not a very difficult task but it can be tricky if you do not look into the technicalities. There are two very important things while choosing a diving light: The beam and The beam angle.

The Beam: The most important part of the light is its beam. The beam must be concentrated in the centre and must not be too wide. A wide beam will reflect in the diver’s eyes decreasing the visibility. A beam that is 70% to 90% concentrated in the centre is said to be good.

Beam Angle: Beam Angle defines the purpose of your light. If you need to look into dark spots or venture into murky waters a tight beam will be appropriate. If the waters are clear and you need to get a broader view then a wide beam will suffice.

The Difference Between Primary and Secondary Lights

A simple thing to know as a diver is that you need to carry two or more lights when you are diving into a much deeper spot. One of them should be a primary diving light and the other, a secondary one.

  • Primary Diving light: The primary Diving light is brighter, more durable and has a longer battery life. It is the diving light mainly used for your diving adventure.
  • Secondary Diving light:  It is a compact light mostly used for backups. The smaller size and a narrower beam serves you good in case of emergencies.



Flashlights are a vital part of your diving journey. Choosing the right flashlight will enhance your experience and also ensure greater safety. Don’t just go for a more affordable light. Make a smart choice and choose a flashlight that does it all for you.

The way we see it, VOLADOR 3 CREE Suba Diving Flashlight seems like a promising one.  It not only provides greater brightness but also lasts a good amount of time. It covers a very long range and is sturdy enough to stand the pressure deep underwater.

For all the beginners, this can be a great kick start to their diving journey.
