Keys to Success:
Socket shadow that occurs where luminaires butt against one another is a common problem. Consider whether the light has room to spread out, or whether the luminaires should be staggered to overlap and eliminate these dark areas.
Geometry of the cove should create an opening large enough for light to
leave, as well as for maintenance of the luminaires.
Cove-specific luminaires exist, which incorporate reflectors and optics that drive light out of a cove in a very efficient manner.
Cove geometry should be designed to eliminate the possibility of lamp visibility.
Wall slots integrate continuous linear sources concealed and directed downward to create a wash of brightness on the vertical surfaces of a space. These bands and planes of light can break up a space and add to the perception of lightness by disconnecting the walls from the ceiling.

Consider the materials and craftsmanship of the wall being lighted. Because of their grazing nature, wall slots tend to show off imperfections. Beware of specular or shiny wall surfaces as they tend to reflect images of the lamp.
Under cabinet lighting is a good way to localize task light. This can be accomplished with a variety of source types, but color rendering and color temperature should always be a priority.
Keys to Success:
Under cabinet lighting should be accomplished with a solid front luminaire or include a fascia or proper geometry to eliminate the possibility of lamp visibility.
Under cabinet systems can include local switching at the task location or
may be controlled from typical wall switch locations.
Under cabinet systems can utilize luminaires as small as 1” × 1” linear incandescent or more robust puck lights and linear fluorescent sources.
If linear fluorescent lamps are used for under cabinet light, they should be
specified with good color rendering and color temperature in mind.
Consider the location for the transformer that is required for the low voltage sources commonly used.
Suspended soffit panels and floating lids are good ways to reduce the scale of space and cast a volumizing light upward. Such systems can be very simple structurally and can make use of common sources like linear fluorescent strips. With the addition of inexpensive color filters, a dropped lid can transform the mood and spatial effect of a space very thoroughly. Dropped soffits can serve as the anchor for seating areas, office work stations and retail displays.
