How to choose a Scuba Diving Light?

Scuba diving at nights, caverns, caves and wrecks require scuba diving lights, but lights can be useful for the day time diving too. If you use a dive light for the above listed specialties, you will need more than 1 dive light. Tech divers have at least 3 dive lights, one primary and two backup lights.

Primary and backup dive lights come in rechargeable and non-rechargeable batteries. The benefit of non-rechargeable lights is the cost of the dive light, but long term, the rechargeable models are a better deal. Primary lights are larger models with strong power and wide beams of light. The lights have long handles and are usually too big to stick in a BCD. Backup dive lights are smaller and are starting to get more intense light. These lights can be clipped on the BCD.

Your dive light requires proper maintenance. The following is the best way for maintaining the dive lights:

Rinse in fresh water.
Rinse the light around the switches and O-ring.
Dry light.
Open it and remove the batteries.
Lightly lube the O–ring (per manufacturers instruction)
Reassemble the dive light.
Store the dive light in a cool, dry place.
If you are not using your dive light for any length of time, disassemble it and remove the O-ring.

Any questions about the servicing of your lights, contact the manufacturer or local dive shop.
