How to Choose a Dive Light

Your dive light

To light up the night, you need a diving light. This is your main source of light in night diving. The day, you can use it to watch in the holes and cracks. Diving lamps are also useful for exploring the Interior of the wreck, and the underwater caves (these types of dives require special training).

Also called: waterproof lamp, lamp diving, underwater lighting, canister, HID, tungsten lamp lamp lamp lamp, LED lamp.


Styles

There are two basic styles of dive lights, with rechargeable batteries or disposable batteries. Also consider the type of used bulbs.

Flashlights-The choice extends from some small compacts to use day or as backup for the night divelights, the wreck diving and diving in the cave, until big type lamps lanterns, which are the main lighting source when diving in darkness.

Canister lamps-Used mainly by divers wreck or cave, canister lamps consist of a battery to the waist and connected to a small lamp by a cable. Canister lamps give, in general, a better brightness (although this is changing as the lighting technology is advancing and makes it more powerful lamps).

Necessary features

Watertight and pressure-resistant flashlights -All diving light is designed to exclude water and resist the pressure of the depth to which it is calibrated.Avoid the “water resistant” lamps that are not intended for diving because they can break under the effect of pressure.

Durable and reliable-The diving environment did not spare equipment. Diving lamps must be strong enough to resist wear.

Desirable features

Rechargeable batteries-Unless you use your lamp that very rarely, the rechargeable batteries are preferable for powerful lamps. They are profitable and they avoid disposable batteries. Many lamps have best performance with rechargeable NiMH batteries with disposable batteries, so not only you save and preserve the environment, but you also have superior performance.

Optional features

Size-although the powerful lamps are smaller and smaller, there is a relationship between size and power. The lamps are the best choice for use as emergency lights and day. On the other hand, large lamps are preferred for night diving, wrecks or caves. They are sometimes called the main lamps, because they are your primary lighting source.

Tungsten halogen, HID, LED lamps-Types of bulbs are changing rapidly and allow the lamps to shed more light with less power. Tungsten and halogen bulbs are less expensive, but are not as powerful and draw more on the battery. HID and LED lamps are the most modern-a 10-Watt HID lamp illuminates as much as a 50 Watt halogen lamp while using only 20% of the energy required for the halogen. LED lamps are still more effective and much more durable.

Disposable/rechargeable batteries-The modern lamps use “AA” size batteries or other common models, and accept either rechargeable and disposable batteries. This means that even if you rarely use your lamp, you can use rechargeable batteries. If you want your lamp is always ready, but that you do only once a year, disposable alkaline batteries of good quality are a good choice.

Tips

  • Don’t buy cheap lamp. As for most of your equipment, when you can’t decide, even with the advice of your store, it is best that you invest in the best possible system.
  • Be formed. Sign up for the PADI specialty in the PADI specialty of wreck divingnight divingor the PADI specialty diving cave if you are interested in these activities.
  • Read the instructions of your rechargeable batteries. The batteries have different characteristics so require different maintenance techniques. The worst thing you can do to NiMH batteries, for example, is to not use them – when they are not used they need to be recharged every month.
  • Two rules for batteries: never mix full batteries with other partially full and never use different types of batteries at the same time, even if the lamp accepts them all.Always use the same type of batteries at the same time.
