Diver's Guide to Dive Lights
A dive light is a portable light source that a diver carries while underwater to illuminate the underwater environment. Self-contained lights are typically carried by scuba divers, while surface supplied divers may use a separate cable supply. Regardless of how the dive light is powered, it is an important piece of equipment for diving safety. Read on to learn more about the different types of dive lights. This guide will help you choose the best light for your diving needs.
The Mares R15 dive light offers 900 lumens of bright light, a magnetic switch that you can lock to prevent accidental powering on. The beam width is adjustable, from 12 degrees to 75 degrees. Its body and tempered glass head are made to withstand the roughest conditions. The MiniQ is also lightweight and comes packaged with a mask strap. It can be used in cave, wreck, or deep tech diving. Alternatively, the DiveRite EX35 Primary Canister Light is the ideal dive light for hardcore techies. With a battery life of over two hours in 100% mode, it can easily stay on your dive equipment for up to five days.
The Mera dive light features a built-in camera. It is capable of capturing HD video and four-megapixel photos. It offers a 1,000-lumen output and adjustable power settings. It can produce a 12 degree spot beam for normal diving, and a wide 120-degree beam for video use. The light is water-resistant to 200 feet and can operate for up to 2.5 hours on high power. The Mera dive light is also waterproof to 66 feet and is compact enough to be used in most dive environments.
The main difference between the HID and LED dive lights is the type of bulb they use. HID dive lights produce a white beam, although some models have hints of green or blue. However, they are more expensive and delicate than LED dive lights, and are generally reserved for technical diving. LED dive lights are becoming the preferred choice for recreational and technical diving, and their durability has increased. You should consider buying a LED dive light if you are going to be underwater for a long period of time.
Some dive lights are powered by batteries and are rechargeable. Others run on disposable batteries. Choose one with a rechargeable battery if you'd prefer to be eco-friendly. A good option is one that offers a battery backup and multiple flash settings. Most dive lights can also operate at depths of 100 meters. If you're planning to go deep and don't have an external battery, then a rechargeable version may be a more convenient option.
To ensure that a dive light is waterproof, it should have a long run time. A typical fun dive usually lasts 45 minutes to an hour. If you're going deeper or are planning to go deeper, you'll want a light that can withstand water entry and exit, as well as an emergency. However, if you don't plan to stay underwater for more than an hour, a rechargeable light won't be much help.
