This set includes two Blue Bag-O-Lantern's which attaches easily to existing Cornhole boards, with either the included screws or with Velcro (not included). Each light is made up of a collection of eight high brightness white LED lights that are arranged in a circle pattern that encompasses the hole. The LED's are encased in high impact clear acrylic with a gloss white back reflective surface to help distribute the light evenly up towards the top of the board. The LED's have an estimated life of 100,000 hours and is operated by a 9V battery (not included) that will supply approximately eight hours of fun. The battery compartment has a convenient on/off switch for easy use.
