Outdoor wall light Harvard - a fusion of nostalgia and modernity With its linear exterior and combination of Glas and metal, the purist outdoor wall light Harvard embodies a very modern style, while the tubular retro LED bulb (not included) is reminiscent of times gone by and evokes nostalgic feelings. When choosing the bulb, you should not only pay attention to the look - filament or Vintage bulbs are recommended - but also to the length. The tube bulb should not be longer than 19 cm.
