Review on Eisco Labs Acrylic Light Pipe: Illuminating Innovation for Precise Optical Experiments by Christopher Gonzalez

This is not a flexible hose. This is hard plastic. It can be carved with a dremel, sanded down with sandpaper and fully finished with a small burst of flame. I cut off an inch from this tube and burnished it with fire. In my RV, I drilled a hole in the case to hold a light tube directly in front of the IR sensor in my AV receiver. The light guide is inserted. I can operate my AV receiver with the doors properly closed. Happy wife.
