Choosing the Right Cavern Dive Light

Cavern diving is deep, dark, and might be extremely new for some divers. If this is the case for you as a beginner or novice diver, the right cavern dive light will make your diving excursions a little easier and more enjoyable. So before you invest in a new light, consider a few of these tips to find the perfect one.

Cavern Dive Light Type

Should you choose canister or flashlight style dive light? Canister lights have batteries with a separate head allowing for more maneuverability of the light head. This makes it an ideal option as your primary light. A flashlight is limited in size, mobility, and depth, so it is an option for a secondary or backup light.

Cord

The canister cord length should measure approximately the distance from your right hip to your left hand (when fully extended). If cords are too short, your diving capabilities are greatly hindered.

Beam Width

Narrow beams are used for cavern diving as this allows for concentrated, bright beams. Brighter beams also make signaling easier, if you encounter other divers for communications.

Depth Rating

It is important to ensure your light is rated for the depths you will be diving. The deeper your dive, the higher the rating should be to avoid your light malfunctioning during the dive.

Bulb Options

Halogen and HID (high intensity discharge) lights are available, but for caverns, LED is the best route to choose. The light is steady and bright, energy efficient, quick to reach full output once turned on, and the chips are durable and rugged. Overall, cavern dive lights with LED bulbs are extremely reliable.

There are several dive light options from which you can choose for cavern and cave diving, both for your primary light and your secondary dive light.
