Lighting using a 2 point source

Hi, I use to  be able to apply a glow material to a cube and light an object to create a shadow. But now the glow material does not have glow setting and doesnt seem to work, im presented with other options. Can you still setup a rig like below? (last time I used dimension was a year or so ago).
