Plaques are made from a strong acrylic and stand 12 3/4 inches tall and 11 ½ inches wide. All designs are carved into the acrylic so there is no fading or wear. Each plaque uses six low voltage LED lights and come equipped with a 12V/1A power supply you plug right into the wall or you have the option to purchase an 8 AA battery holder. Batteries are not included. The LED light strips are connected to power supply with a 5.5mm / 2.1mm barrel connector. Each strip comes with a total of 12 ft of black cord. The lights give every plaque a bright, vibrant display and you can choose from any color (Red, Purple, Blue, Pink, Yellow, Green and White).
