Kenroy Home 32829SIL is an easy-to-assemble lamp that can be put together in approximately 5 minutes. It has a harp and shade holder that can accommodate a 150-watt maximum medium base type "A" 3-way bulb (not included). The lamp has a polarized plug to reduce the risk of electric shock, and it should not be used with an extension cord unless the plug can be fully inserted. If the lamp does not light, check the plug at the outlet, the bulb for a broken filament, or contact your distributor or place of purchase.
