Outdoor lighting. Outdoor lighting serves a dual purpose: enhancing the beauty of your landscape and providing safety and security for your home. Effective outdoor lighting design is simple and avoids over-illumination. Lights should be positioned in unobtrusive areas and areas that require safety or security illumination. Consider the outdoor areas you will be using at night and for what purpose. For example, if you plan to barbecue, adequate lighting in the grill area is necessary. Choose durable, weather-resistant lamps that can withstand outdoor conditions. Portable patio lamps are also a great addition to your outdoor space, as they can be taken wherever you need light. These lamps can be plugged into an outdoor outlet and are available in a variety of styles. Additionally, citronella torches and oil lamps not only add to the overall ambiance of your patio, but also help keep insects at bay. With a well-planned outdoor lighting design, you can enjoy your yard after dark and create a dramatic new personality for your landscape in the evening hours.
