The UCO Mini Lantern is UCO's version of the Tea light lantern which uses the small tub candles for up to 5 hours of light. Lightweight 3.2 oz. and compact 4 x 2.5. The Cocoon is a Patent pending neoprene stuff sack designed to protect the glass chimneys in a drop of up to 3 feet. It will fit most major brands of candle lanterns. A specially designed vent in the base of the lantern provides cool air to supply the flame with needed oxygen. The UCO Mini Candle Lantern is ideal for ultralight hiking, bike touring, world travel, and makes home use of the ubiquitous tealight candle much more appealing. COCOON NOT INCLUDED.
