Underwater Flashlight for Diving

To provide illumination at night, you need at least one dive light as a primary light source. During the day, you can use an underwater torch to look into cracks and crevices.

This guide explains what kind of lights scuba divers use and the key styles and features to look for when choosing the best dive light for your budget.

Standard Features of the Best Diving Light

Divers use a light to explore inside wrecks and in underwater caverns and caves. A good dive light for a new diver should have:

Pro Tip: There are two basic styles of dive lights with different options for rechargeable or disposable batteries, and the type of bulb that it uses.

Reasons Why Divers use a Dive Light

Flashlights range from small, compact lights used during the day or as backups for night, wreck and cave diving, to large lantern-style lights that are primary light sources when diving in the dark.

However canister lights are used primarily by wreck and cave divers. Canister lights supply a compact light via wire with power from a battery in a canister carried on your waist.

Canister lights are usually much brighter (though this is changing as lighting technology advances make smaller lights more powerful), so this makes carrying the larger batteries more convenient.

Underwater Torches: Batteries and Bulbs

In general, the initial outlay for a rechargeable system will cost more. But, they tend to be the preferred option for divers who use them a lot.

Remember, bulb and battery power will have an affect on the brightness. Even so, a torch with disposable batteries should be ideal for occasional diving.

Some of the main differences between the halogen, xenon, LED (light-emitting diode), and high intensity discharge (HID) bulbs for underwater torches include:

Beginners will find it easier to carry a dive light in their hand if it has a good sturdy grip and handle.

Nonetheless, you can buy small lights that mount the wrist, on a mask, regulator hose, or on underwater camera strobes.

You can also improve battery power usage if you buy a dive light that features a multiple power mode. If you enjoy night diving, you may also get to use chemical glow sticks and safety marker lights.

Pro Tip: Never mix fresh and partially used batteries, and never mix different types of batteries, even if the light accepts all the types. Always use the same type of batteries in a single fresh set.
