Buying a quality dive light is one of the best investments a diver can make. Not only do they provide essential illumination underwater, but they can also be used for signaling, communication, and navigation. However, it cannot be easy to know which one is right for you with so many different lights on the market.
1. Consider Your Diving Needs
It is important to purchase a dive light that suits your specific diving needs. For example, if you are an underwater photographer, you will need a light with a narrow beam to help you focus on your subject. Conversely, if you are looking for a light to help you navigate dark waters, you will need a light with a wide beam. There are also lights designed for use in caves and wrecks, which produce a bright, diffused light that helps to prevent disorientation.
2. Focus on Water-Tight and Pressure-Proof Products
One of the most important things to consider when buying a dive light is whether it is water-tight and pressure-proof. After all, you will be using it underwater, so you need to be sure that it can withstand the elements. There are a few things to look for when assessing a light’s water tightness. First, check the O-ring. This small rubber ring sits between the light and the battery compartment. It should be in good condition and properly seated in its groove. Second, take a close look at the seam where the body of the light meets the lens. There should be no gaps or cracks. Finally, give the light a good shake. If you hear any rattling, that means there is an air leak.
3. Research Products’ Lumens
When shopping for a new dive light, keeping lumens in mind is significant. This is a measure of the light’s brightness, affecting how well you can see underwater. A light with a high lumen rating will be brighter and more powerful, but it will also use more battery power. As a result, it’s important to balance lumens and battery life when choosing a new dive light. A good rule of thumb is to choose a light with at least 1000 lumens if you plan on diving in low-light conditions. This will ensure that you have enough brightness to see clearly, without sacrificing too much battery life.
4. Think about Type of Battery
The type of battery your dive light uses is also important to consider. Most lights use either alkaline or lithium batteries, but some use rechargeable batteries. Alkaline batteries are the most common type, and they are widely available. However, they don’t last as long as lithium batteries. Lithium batteries are more expensive, but they offer a longer runtime and perform better in cold water conditions. If you plan on diving in waters that are colder than 60 degrees Fahrenheit, it’s best to choose a light with lithium batteries. Rechargeable batteries are another option to consider. These can be convenient because you don’t have to worry about buying new batteries all the time. However, they tend to have shorter run times than alkaline and lithium batteries.
With so many different dive lights on the market, knowing which one is right for you can be challenging. By following these tips, you can be sure to find the best dive light for your next scuba diving trip.
