The Lighthouse bio flame has been designed for both indoor and outdoor use. The base is made from Polystone and its weight combined with the square base design makes the Lighthouse very stable. The protective steel cover produces a mesmeric combination of shadow and flickering fire creating an almost torch like quality to any entrance, reception or lobby environment. The bio ethanol fuel reservoir is made of stainless steel and sits in the heart of the glassfire generating flames for up to four hours.
