Keys to Success:
Consider the geometry and location of the luminaires to eliminate the possibility of lamp visibility.
Consider the material above the soffit. It should be reflective enough to
spread the light back into the room. Specular (shiny) surfaces should be avoided as they will reflect the image of the lamps or luminaires.
The suspension distance should be considered to ensure that light has room
to inter-reflect within the space.
Luminaire placement should be studied to ensure even lighting without apparent stripes or hot spots.
Backlit walls and large glowing panels add a lightness that transcends typically constructed spaces. The challenge with large scale applications is achieving an even plane of light that truly appears to be self-luminous.
Keys to Success:
Ample space behind the backlit panel must be available for light to diffuse evenly.
Maintenance and access must be designed into the panel system.
The diffusing properties of the panel material will dictate the geometry and luminaire layout. Be sure to mock-up the application with the specific material that will be used.
Millwork integrated lighting creates a very distinct and attention drawing display element. This type of feature is commonly used for retail display and food and beverage display.
Keys to Success:
Consider the heat output of the light source and how it will affect the object being lighted.
Subtle changes in source location will affect the light quality and should be
studied and mocked-up.
Display lighting can be accomplished with a single line of light; both top and bottom light, individual puck lights or a combination of treatments as shown here.
Consider the location for the transformer that is required for the low-
voltage sources commonly used.

Daylight and Electric Light Integration Details
Some of the best lighting details are those that combine the effects of daylight and electric light sources. The human affinity for the quality, color and texture of daylight crosses over to electric light applications that can mimic these same traits. Well thought-out details that manage to fuse the two together can create remarkable lighting effects that can define a space. These details have a dynamic character that will change through the course of a day while maintaining a desirable effect.
If the electric light component can be put on a dimmer, a photo-sensor
that detects variation in light levels can be implemented to control the exact quantity of electric light being contributed to augment the daylight. Such systems ensure that the electric light is not wasted.
Typical skylights can be augmented with the addition of upward-directed light sources. The electric light system can be as complex as a shelf or cove system or as simple as surface mounted luminaires that cast light upward. Under daylight conditions, sunlight will diffuse through the skylight material. When activated, the electric light will wash up, filling the volume of the skylight and reflecting back into the space.
