Kenroy Home 32438BLU is a portable lamp with a polarized plug for reduced risk of electric shock. It requires assembly and takes approximately 5-10 minutes to complete. The lamp uses a 150-watt maximum medium base type "A" 3-way bulb (not included). To replace the bulb, unplug the lamp, unscrew the existing bulb, and replace it with a new one. 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. With its stylish design and easy-to-use features, Kenroy Home 32438BLU is a great addition to any home.
