If you don't already have light fixtures in the ceiling, you would have to plan on having the necessary wiring done. It is likely that 4 (or more) lights would be more appropriate.

Have you considered alternatives such as track, wall wash lighting?

Just thought I'd post a picture of my lighted art work. We ended up using just one 4 inch recessed low voltage light with the aiming elbow trim. To me it does not look like it needs the 4 or more lights that the previous poster suggested.
There certainly is a big difference in how the art looks with and without being lit.
First picture is with recessed light off. The flash made a white spot on picture.

Second picture is with light turned on. No flash needed on camera

Very useful. Thank you. It helped me

An old thread, but framing projectors have become inexpensive. A dramatic way to light art.
