The Burning Blue High-Power Fire-Starting Laser Torch starts fires without matches or lighter fuel. It projects a visible blue beam that you focus on prepared tinder to create the first flame. You then feed that flame with fine kindling to build warmth, cooking heat or light.
The 450 nm beam is absorbed by dark, dry, thin material, which ignites at a working distance of six to eight inches. Pale, damp and thick material reflects the beam and will not catch. Outside the focal point the beam spreads and nothing ignites.
Char cloth works best. It is matte, porous and already carbonized, so it absorbs almost the whole beam and goes to a spreading ember. Black paper, black card and black electrical tape also catch. The torch is not a continuous tool: use it for 30 seconds, then let it cool.
