The lamp's tubular body, which varies in length between ten and 15 centimetres, is separated from the wall only by a thin, rectangular base.
This allows the light emanating from both ends to highlight the texture of the surface on which it is placed, as well as playing up structural features on the facade, such as columns.
Lance supplies both direct light aimed at the building exterior, as well as acting as an indirect light source for its immediate surroundings.
The angle between the light and the wall can be adjusted, from a linear beam to a more outwards-facing 45 degree angle.
Its internal LEDs deliver a brightness of up to 10,000 lumens, and their colour can be changed from white to red, green or blue.
