Those that still remember carbide lamps know that lighting was generally good at that time:

A group of cavers with carbide lamps would illuminate smaller passages evenly, giving a nice feeling of the room as a whole. Electric lamps often only have a narrow light angle in order to render their low light output into something halfway useful. But then, the room illumination is gone - each caver has a small circle of light, the rest is darkness.

Scurion® brings the room illumination back with its very wide, smooth, high power room light. For finding hidden passages or generally seeing farther, Scurion® lamps also feature a very intense, narrow spot - see if this hole continues in 50m or not...

What is good for cavers is good for anybody working in the dark - you can act almost under daylight conditions!
