Don’t limit lighting to downlights. Depending on the location consider wall sconces or uplighting to create a softer ambiance and avoid potentially harsh downlighting that can cast ominous shadows.
The most common use of up lighting is in a recessed cove around the top perimeter of a room. To maximize light output use a T5 fluorescent or LED light source that will wash the ceiling with light. This helps to create a brighter ceiling that bounces and reflects light throughout the space without glare. Combine this with lots of natural daylight to increase the overall light levels in a room.
If you enjoy art in your bathroom accent lighting will show it off best. Recessed directional lights provide focused illumination for each piece of art — or in this case for an alcove dedicated to a sculptural bouquet of flowers.
