Mr. Light 13 Watt Compact Fluorescent Screw-In Anywhere True UV Blacklight
Mr. Light has the perfect way to convert your den into a true Halloween party room. This 13 watt compact fluorescent blacklight plugs into any normal recessed ceiling socket.  Use several to make the whole room glow or use together with a strobe light for glow and strobe effect for dance parties. If you don't have a recessed ceiling fixture, just screw this light into any incandescent lamp socket. Also great for attracting trick-or-treaters when you replace your normal porch light with an eerie glow and to let the kids know that you are open for treats.
