There are many ways to hide the light source. Fluorescent lights can be placed in special panels, usually made of plaster constructions, that we build on the ceiling or on the wall and give a soft and discreet light.They can also be placed under kitchen cabinets or in furniture showcases. A lighting body can be placed on the wall recessed and cover the lamp as much as necessary to illuminate without disturbing the eyes. This way of lighting can be applied to the stairs, where the lamp is placed low, recessed in the wall, it is covered in its upper part so as not to blind the eyes, and casts the light downwards to illuminate the stairs.
