Nostalgic Gero outdoor wall light: glass in a cage-like aluminium lampshade Glass combined with aluminium is a popular choice for outdoor lamps, as both materials can withstand various weather conditions when processed to a high standard. The Gero outdoor wall lamp fits into this category and impresses with various eye-catchers. The glass lampshade sits behind a cage-like construction made of aluminium and with a real nostalgic charm. In addition, the Gero outdoor wall light has a small cantilever to distance it from the wall. The curved arm flows into the flat, semi-circular top of the lamp. The socket for the bulb sits below this. Energy efficiency class:A++
