Simple Zaio wall light with indirect light emission The Zaio halogen wall light is characterised by its discreet design and can be installed almost anywhere in the home without looking out of place. The halogen light source is not directly visible, but only provides indirect light, which creates a pleasant atmosphere in the room. Perhaps the white surface may seem too plain to someone - no problem, as the plaster surface can also be customised in colour. Sandpaper and gloves are included for optimum surface treatment before painting or decorating.
