Wall washing is a lighting technique in which vertical, indirect lighting is placed in the ceiling or floor at a wider distance from the wall. This way, the light can fall down on the wall in an equal, uniform way. This provides a "washed" effect of the wall so that shadows and defects disappear from the wall.
Cove lighting: lights are often directed towards the ceiling or the top of the walls of a room. the lighting may be concealed behind valances, above crown moldings, or built into ledges or recesses, but essentially the lighting is indirect. Cove lighting has the potential to breathe new life into a dull room.
Up Lighting: is any lighting that shines upward. For exterior applications, it is used to light up architectural features of a house, tree, and other areas of the landscape. For interior applications, uplighting reduces ceiling dark spots and shadows while affording the user additional, glare-free indirect lighting.
Fluorescent bulb is much more efficient as incandescent bulb at producing light at the wavelengths that are useful to humans. It run cooler for the same effective light output and also last a lot longer hours.
