Lamp posts are just one of the many lighting options for your yard. Many indoor lighting designs are also equipped for the outdoors. More recently, a popular type of lamp post are those infused with citronella. These not only add a decorative element to your yard but also keep annoying bugs and insects away. European-style globe lamps are also in high demand, and can cost as little as $130 per globe. Venetian, Victorian and Holland style lamps are also popular right now because of their original designs. You can find garden lamp posts at any garden shop. However, specialty lamp and lighting retailers might provide you with a wider selection of lamps for your garden.
