In ore mining, long holes are drilled into the ore body which are then filled with explosives. After firing, the mines' tunnels must be secured before loading, this is done by inspecting the tunnel and surrounding areas. This work requires a really good light. In cooperation with LKAB we have developed a lamp that can handle the hard environment of the mine. With special electronics and shielded cable, it offers both an unrivaled light and good communication with radio.
