noun
lantern
LAN-tern/ˈlæntərn/
A portable lamp with a protective transparent enclosure.
The camper carries a glowing lantern along the dark path.

Etymology
The root meaning “to shine” produced a word for a torch or beacon fire. A lantern preserves that light-giving function in a portable lamp with a protective case.
In context
although it gets a lot brighter it also gets yellower. This is unique to this lantern, neither white gas one does this.
