The lantern has a shelf life of almost ten years and is a useful option as an emergency lamp at the time of power failure. The lamp gives out a luminance of about 2000 Lx, and can continuously work for up to 80 hours. After the usage, the magnesium alloy has to be replaced, and the lantern becomes as good as new.
