Yes, our lanterns are designed to be used indoors or outdoors all year. They can be left outside in rain. However, if it’s in an area on the ground where the water will pool up then you may need to move it as a precaution so it’s not submerged in water. They can also be left outside in the winter with snow and ice. However, if you know it’s about to be buried under snow for a while you may want to move it as a precaution then put it back outside when the snow clears.
