The Stained Glass Style Torchiere Lamps illuminate partial walls and roofs, providing a degree of indirect illumination and increasing the vertical illumination of the space, which of course makes the space feel clearer.
However, this brightness is reduced because it is only "partial". There are in fact special lamps for this kind of upper lighting. Floor lamps mostly, table lamps, and of course wall lamps. There are also lamps that shine up and down together, wall lamps mostly.
