The Holland Bar Stool Co.'s indoor and outdoor LED Logo Clocks are 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 black ABS plastic and the glass face lens has a rubber gasket to seal the weather from the inner clock housing. 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. Accurate quartz movement ensures proper time and is powered by a single, AA battery not included. Whether purchasing as a gift for a recent grad, sports super fan, or for yourself, you can take satisfaction knowing you're buying a clock that is proudly brought to you by the Holland Bar Stool Company.
