I don't know of a luciferase-based teaching kit. However, a similar dramatic effect can be achieved using green fluorescent protein (GFP), which comes from the fluorescent jellyfish Aequorea victoria.
Bio-Rad company (http://www.bio-rad.com) sells a "pGLO bacterial transformation kit" that allows students to transform E. coli with a plasmid containing the GFP gene.
It does require a UV source in order to see the fluorescence. We've used it in classes at the university level with good success.
