This Pittsburgh Panthers indoor/outdoor LED Logo Clock is the perfect way to show your school pride. These clocks are made to handle the outside environment. The casing is made from a UV resistant ABS plastic and the glass face lens has a rubber gasket to protect the clock from the elements. Four LED lights are controlled by a photo eye, turning on automatically when it is dark to illuminate the clock face. LED lights run off 4 D batteries (not included). Art work is digitally printed with UV inks to ensure years of fade free, vibrant colors. This is a great gift for a recent Panthers grad, sports super fan, or for yourself, or you can put this clock in your restaurant, bar, or fan-cave to show off your Pittsburgh Panthers pride. Powered by a single, AA battery (not included). This clock is officially licensed.
