The light is designed for outdoor operation, however storing the light outside without
using it is a risk for damage to light components. For a longer storage time (more than
a week), it is recommended to store the light indoors in a dry and dust free
environment and at room temperature. Proper storage ensures trouble free
replacement procedures. It is strongly recommended not to store any electrical
equipment outside.
