When it comes to scuba dive lights, there are a number of uses for it on different scenarios during a scuba diving and one of the most common uses will be during a night dive, but the scuba dive lights can also be used during cave dives, when you are diving on an over cast days or even by simply looking into a hole or in between rocks on a normal dive day. For any diver, they really know what the light can do when they are under water; it brings out the natural color of the creatures as well as the corals since they lost its colors as the dive becomes deeper due to very little light that reaches the deepest part of the ocean. If you do not have a good dive light, it would be impossible for you to appreciate the amazing wildlife that are hiding in the crack and crevices.
When you are going on a night dive, it is expected that the dive shop or agency will tell you to bring at least 2 dive lights, one will be used as your primary dive light while the other will be used as backup in case the primary light will fail in the middle of your dive. If any of you dive light fails or both dive lights fails, then it is highly recommended that you call off your night dive.
For your primary dive light, it is best that you choose a wide beamed light that will illuminate wider area and will help you overcome the darkness during your dive. For the secondary light, you can use smaller light beam as this is best for illuminating small ocean creatures.
Lights that illuminates brightly are not often great for diving since the water has large amount of particles and that you will be able to see less since you will also be lighting up the particles more than anything else.
If you are an underwater photographer or videographer a very bright light can create hot spots not unless you have a bright wide angle beam. Visit this website at http://www.ehow.com/way_5408246_homemade-underwater-lights.html for more facts about underwater lights.
When you are a recreational diver, you are very happy with having cheap torch with short burn, but for those who are professional divers, videographer, photographers, cave divers, wreck divers, they would choose to have the high quality bright torches that can last longer.
If you are looking for a dive light, check for the burn time of at least twice as much as your dive can last and it is also important that you look at the deep rating such as 50% extra. When you are able to choose a good dive light, it often have a rating of at least 100 meters of more which means that it can hold up to the pressure.
