Delphia patio light for decorative outdoor lighting The metal body of the Delphia light is a modern take on the classic lantern. The light is effectively emitted into the surroundings through the vertical struts and you can catch a glimpse of the bulb (E27, not included). Thanks to the 5 metre long cable, the light can be placed relatively easily anywhere on the terrace or balcony. Delphia can be used as a floor or table lamp both indoors and outdoors.
