Only the switch puts this light out. This Zippo Rugged Lantern™ can withstand a 5-foot drop and stay out all night in the rain. Through every condition, the Lantern shines with the brightest light of any LED lantern made. You can even make the lithium-ion battery last longer by adjusting the brightness from 100% to 50% to 10%. In case of an emergency, the Rugged Lantern™ has an emergency S-O-S setting too.
