"Is it ok to install these lights behind an existing 20 amp outlet?"

If you install them behind an outlet, they are not going to cast much
light. ;-)

They will light the space inside the wall, between the 2 studs on each
side of that outlet. Maybe he could then put a glass block or two into
that wall so the light can be seen.
