Bright idea for unexpected lighting: Look for opportunities to install light fixtures in alcoves tray ceilings and wall niches to trace interesting lines. Notice the hidden lights in the ceiling alcove above the cylindrical fireplace mantel here.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
Consider your lighting preferences during the initial design phase of a new build or renovation. For example if you want three pendant lights over your dining table instead of one or two that should be taken into account before construction starts.
