The Cog Light from design house Blue Marmalade is a unique, sophisticated interpretation of the pendant concept. The body and broad ?teeth? of the cog are all formed from a single sheet of moulded polypropylene, giving the Cog Light a wonderful internal harmony and unity of form. It?s practical, too: the cog light is robust enough to take a 100w bulb without scorching or deforming, meaning it?s ideal for lighting heavily-used spaces or rooms that are used for reading.
