I have a room with one spot light at the ceiling that is not very bright.
Using a bright bulb just light up a spot in the room brighter.

I bought a floor lamp for the room. Is there a way to make the lamp turn on
when the ceiling spot light is on?

In other words, flip one switch and turn on both the hardwired ceiling light
and a floor lamp.

I can think of an expensive solution using home control system Insteon by
installing an insteon light switch and a lamp module. The light switch not
only functions as a light switch but can be linked to the lamp module that I
can plug in the floor lamp. This cost $100.

Is there a cheaper way?
