Carbide Light vs. LED Light for Caving

Video Transcript

"Before you go in a cave don't go alone and don't go without any guide. It is very very important, it is dangerous. Of course in every cave it is always very very dark, pitch dark and that is why you have to use light. It is not the same if you use this kind of light or this kind of light. This is the carbide light which is run by carbide and water and as they mix they produce acetylene. So the acetylene is going up and the flames hit here on my helmet. Here is another kind of light which is run by electricity. It is better if you want to see far away or you look down in a big shaft to see the bottom. The cavers if they are in a big cave, they have to use two lights which means that they are using sometimes just one but any time you need another one it is there. It is good to have a helmet because sometimes it is like a storm falling down with rocks but honestly you will hit your head many times so it is good protection."
