If you want to make someone surprised in the bedroom the Luminous Fiber Optics Bed Cover is a good start. The Italian based company Luminex creates luminous bed covers with fiber optics woven right into the material. That means what you see here isn’t a cool effect under a blacklight—the bedspread is actually emitting light. The luminous bed covers are available in several different colors and can be powered by either batteries or an AC Adapter. The bedspread runs on a super low voltage so there’s no risk of getting shocked… which is good news for people worried about safety.
