DescriptionThe light is mostly supplied by a "Kick" light (small battery powered LED light). The Kick threw a much wider swath of light than my flashlight or headlamp. This was where light from the entrance was no longer visible. I shut the flashlight(s) off briefly here and experienced the profound darkness available in caves.
