Anyone serious about underwater videography needs to use a dive light. These underwater lights are reliable and should last for a long time when cared for properly. This guide details the main videography dive light care tips.

Checking the Seals

Dive lights are sealed using rubber o-rings to prevent water from getting inside and causing any damage. You should regularly inspect the seals to make sure they haven’t become damaged. To keep them in good condition, make sure you clean them after every dive and lubricate them as needed with a good-quality grease-containing silicone product.

The o-rings can normally be removed quite easily and inspected. New ones the right size can be purchased and used as replacements if necessary. For the o-rings to seal properly there can’t be any foreign bodies on them. Even a tiny bit of hair could be enough to allow a tiny amount of water into the casing which could cause a tremendous amount of damage.


If you plan on storing your dive light for a long period of time, then you should remove the batteries if possible prior to storage. When batteries are not used for an extended period of time they are more likely to leak which could corrode and cause damage to the circuitry inside the light.

Store the light somewhere safe where it won’t get dropped or damage. When possible, also keep it away from direct sunlight to prevent any damage.


After each use you should thoroughly rinse the dive light with plenty of clean water. The clean water will help to remove salt, dirt and any other debris which may have been floating in the water. After rinsing the light allow it to dry naturally before packing it away.

More Thorough Servicing

Although it’s possible to do routine maintenance yourself, it’s worth having a dive light professionally serviced every couple of years. Most dive light manufacturers offer servicing for their own videography dive lights.
