The style of this lamp can be used in multiple interior designs.  It's simple & practical.  I use LED light bulbs that are slightly smaller than an ordinary incandescent bulb but have a full reflective surface.
Each bulb is individually operated by a knob on the top of each cylinder.  You can also plug it into a socket that operates from a light switch & they will come on simultaneously without turning the knobs.  The lights can also rotate to face a wall or ceiling for a more dramatic effect.  A matching floor lamp is also available that has 3 lights with the same sleek styling with some assembly required.   

Pros: Comes assembled, goes with many decors
Cons: None whatsoever
