7. Why is a multifunctional diving light useful?
An average diver can take part in at around 20 diving. In order to fully enjoy all the diving of our trip, we need either more diving lamps or a multifunctional diving light. But why is this? You can ask the question. I will explain my answer to you.
Anywhere you go to dive, it can be organized, depending on 4 topics:
- Cliffs, cavities, alpine garden
- Walls or gardens made of coral
- Night diving with little depth
Of course, there are other options, for example looking at sharks, or closed caves…, but these diving are not the most popular programs among the average divers. This is why I narrowed the examination to the 4 topics above.
In the last few years I took part in hundreds of diving, but still at the moment of jumping into the water it comes to my mind, whether I really need this. But, when I get into the water, most of my doubts are gone, when I experience the weightless floating , and I feel like getting into a colourful dream.
When we are near at a cliff and we are bathing in the sunlight we can see beautiful colours, but only in 10 meters under the surface, and then you can only see the colour grey. The creatures living in these places prefer to hide in the dark, and this makes it hard to see them. Here, for the best experience you should use 3 kinds of lights. It is advised to use 10° bewel-angle search lights in the narrow cracks and cavities, to be able to look into every place and to find what we are looking for. To see the wonderful sight in the bigger cavities and on the walls, you need 90° video-photo light, which is useful at taking pictures and making videos. I f you want to take pictures, of creatures that intend to hide when they feel themselves in danger, you should use the red light, because it will not bother them. For diving in these places, I use the Sparklights Action 7F and RE models.
However, at the walls of coral, people expect to see, a wide range of colours, the sight can be disturbed by the shadows and the disappearance of the colours. Unfortunately, neither the tropical sunlight can deal with the water’s light absorbing effect. In these cases, instead of seeing the original colours, you should use the white search light and the video-photo light intermittently. The red light can also be used for discrete watching and for finding the best position for taking photographs at dusk. For these occasions I suggest to use the Sparklights Action 7F and RE models.
Watching wrecks needs means more extreme conditions. The insides of these wrecks are totally dark, and in some cases closed, which can be scary. From the outside, one side is in most cases covered by a shadow, and if it is not, then you can only see the greyness because of the depth. The multifunctional abilities of the lamp are the most necessary, in these conditions, as it is useful in wide range of places, such as at narrow corridors or at bigger spaces. Depending on your position, you should consider the changing of many conditions, such as, the bewel-angle , luminous power. Needless to say, that in these places the use of the danger signal is inevitable, as there is a possibility of getting lost or entangled. For the most experienced divers, I suggest using the red light, as the animals living in the wrecks prefer living in the dark, and are bothered by the strong white light. I also suggest using the Sparklights Action 7F and RE diving lights for these diving.
For the nocturnal divers the conditions are completely different, as they get into a space where the breathing is harder and our eyes can barely see anything. This is a very hard situation. Unsurprisingly, it is prescribed that every divers have to take two lights with themselves, and if two people only have two operating ones with them, the diving has to be stopped. The multifunctional abilities of the lamp can be fully used under these conditions. You need the 10° bewel-angle for the communication and searching under the water. The 90° is necessary for making videos, but it is useful for the divers without cameras, as it only lights its surroundings with a little light. The video-photo light provides an almost full panoramic picture, thus, the light conditions are similar to the ones that occur during the day. By this, the darkness decreases. For those, who does not use cameras, it is advised to use the search light and the 90° bewel-angle video-photo light simultaneously. Being discrete in the dark has many advantages, this makes the use of the red light the most important. The night provides great opportunities to look at the biofluorescenc e. As It has been mentioned in our previous blog entries, many creatures, such as corals, cnidarians, fish, crabs, glows beautifully, when they lit by the UV and blue lights. I also suggest using the Sparklights Action 7F and RE diving lights for nocturnal diving, as well.
That’s what you can see by using the UV light of the Sarklights Action 7F.

Finally, you can see a video in this link, which represents what you can see at night under the water by using the different functions of the Sparklights Action diving lights.
