Especially if you dive at great depths, a special torch should belong to your basic equipment. This is valid above all if you practise wreck diving, cave diving or deep sea diving. Thereby you cannot take a normal lamp with you under water. Special torchesfor divers are particularly robust. When selecting lighting, you should pay attention to the following points:
Because you have to hold the light the whole time, it should fit perfectly in the hand and not be too heavy.
So that you do not lose it, make sure you have a strap to fix it to your equipment.
The casing should be scratch, impact and pressure resistant, in order to be able to withstand the water pressure. You can possibly purchase a neoprene sheath for it which mitigates shocks.
LED bulbs glow particularly strongly and durably.
What type of torches are there for divers?
In general there is a distinction between different types which are designed for specific purposes respectively.
Floodlight / Spread beam: These produce a broad cone of light. This is advantageous particularly in clouded water. The disadvantage is that a floodlight only has a small range.
Spotlight: This one has a large range, in return only a small cone of light. This is then ideal when you dive in clear water.
Normal beam: If you do not know exactly what the conditions under water are, you can do nothing wrong with this one. The normal beam has a middle range and an average cone of light.
