In Feng Shui a red lamp shade was used in a living room space to bring fame to the person.  Also, a red lantern was placed in the hallway to bring energy and light to the space.  Today, wall sconces and red glass are used for this purpose.  You could place the red lantern in a corner that has nothing in it, if your room is an irregular shape and you want to maintain a good energy level or chi.   Feng Shui realizes that where lighting is placed directly effects the mood of the people in the room. If you want a  feeling of harmony,place the lantern where it will not cause shadows to fall across the activity that you are involved with ,and light the candle in the lantern to cast a yellowish color flame for calmness.   Accent lighting like this lantern ,is said to soften the sharp edges of the room ,creating a good flow of energy and making the environment more peaceful.
