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.
A floor lamp nestled against a window is a smart substitute for daylight so that when the sun goes down an ambient glow will pour in from a similar direction to balance the central light overhead.
Another important ceiling-based light source is the pendant or chandelier. The line between these two can be blurry as a chandelier is essentially just a large (and often more decorative) pendant light. Chandeliers also are more likely to have multiple bulbs (which help create more layers) but what is or is not a pendant is still a gray area especially with more modern fixtures like the one here.
