The Coso lamp from House Doctor must be said to be functional design. It comes with an LED bulb and timer, so you can move it around and hang it wherever you like. It doesn't need to be plugged into a socket, making Coso the obvious choice for creating cosiness both indoors and out. With its aesthetic design, it can be hung on its own, in a cluster or in a row. You might even have a favourite screen that the lamp could look great with. It almost doesn't get more practical than that. Note: Batteries are not included.
