refers to mounting outdoor lights on trees

Uses for Outdoor Light Bulbs Outdoor lighting is essential to property owners for many different types of uses. Planning is required to achieve the best lighting effect. If properly installed, outdoor lighting can transform ordinary items such as any shrubs, gardens, walkways, decks or porches into a central attraction. It also allows for safely illuminating walkways and stairs. To begin preparing a plan for the type of outdoor lighting, it is best to determine the purpose of the lighting and consider the intended result. Reasons for Outdoor Lighting One reason for using outdoor lighting is security. Providing a safe and secure environment is paramount to any homeowner. An illuminated property discourages people from trespassing illegally and discourages crime. Another reason homeowners use outdoor lighting is safety for themselves and visitors. Adding tier lights along steps and pathways can create a safe course around a property to prevent falls. Using outdoor lights to illuminate a home address can assist visitors in locating a house. Ambiance is another reason for planning outdoor lighting. Outdoor lighting can be used to accentuate the colors of plants and textures of a lawn, building or landscape. The lights can extend outdoor parties and events into the evening and provide enjoyment during every season. Types of Outdoor Lighting Effects There are many different types of lighting effects to choose from. Accent lighting is used to feature a certain aspect of the landscape to provide contrast. Cross lighting refers to mounting outdoor lights on trees, fences or other objects to accent objects. Downlighting involves installing lights at higher altitudes so that the light is di dwyane wade jersey rected downward to create atmosphere. Grazing lights utilize a light beam to just barely illuminate the texture of an object. Silhouetting refers to using a light to illuminate the back of an object for a contrast effect. The items appear to have a glowing radiance around them. Shadowing involves placing a light at the lowest level and using it to cast a shadow from the object. Spread lighting is a technique of using circular motions of light to illuminate items of interest such as shrubs.  ray allen jersey Uplighting refers to the use of fixtures mounted low and directed upwards to highlight a focal point. Types of Outdoor Light Bulbs Fixtures commonly used for outdoor lighting are spreads, spots, floods, mini-spreads and fixtures. Each type of fixture is ideal for certain lighting effects. In regard to energy efficiency, fixtures with the Energy Star label are recommended. These energy efficient fixtures provide monthly savings on light bills. There are many types of outdoor light bulbs including low voltage and shock-free lights that are cost effective and easy to install. They are relocated easily and are safe. Compact fluorescent light bulbs are also known as CFLs. They provide substantially more hours of luminosity than other lights. They also use far less energy than incandescent lights which use more wattage. They are sized so that they fit standard sockets. Other advantages include the fact that their compact size makes them very versatile when it comes to exterior lighting. The initial cost of CFLs is greater than incandescent bulbs, but one CFL is the equivalent to sixteen incandescent bulbs. It is worth noting that if a dimmer is involved, the CFL should be labeled for this type of use. For outdoor use, it is recommended that the bulb is labeled for outdoor usage. CFLs cannot handle power surges well, so workshop use should be avoided. Halogen lights are similar to incandescent lights because they u miamiheatshop se the same filament technology to create light. Halogen lights are more expensive than incandescent lights because they last longer and  lebron james jersey are more efficient. The light that halogens generate is the brightest, cleanest light available. Halogens should be cleaned, installed or removed with a cloth and not hands because the oils from human skin will make the bulb burn overheat and decrease its endurance. Incandescent are the most common varieties of light bulbs. They are reasonably priced, and come in many different hues and styles. When it comes to outdoor incandescent lights, parabolic aluminized reflectors, or PAR; are outdoor flood light bulbs that precisely control light. They are able to resist moisture due to weatherproof casings. Their main use is for floodlights and spotlights. Parabolic aluminized reflectors are used in recessed and track lighting. High-Intensity Discharge Lamps or HID are comparable to incandescent and fluorescent bulbs. They function by producing light within a glass tube filled with gas and metals. The gas helps start the lamps while the metals evaporate to generate the light. Inside the tubes is an electrical arc which is struck across tungsten electrodes to create light. They include metal halide, self-ballasted mercury and mercury vapor lamps. All of these varieties except for self-ballasted lamps require auxiliary equipment for use. Ballasts are starters are needed to activate the lamps. HIDs are able to generate a higher amount of light from a smaller bulb than incandescent and fluorescent lights. HIDS are used for projects that require energy efficiency and high levels of light to illuminate large areas. HIDS are popular with public areas like roadways and parking lots. However, they are being used increasingly in residential settings. Low-pressure sodium lights are the most efficient commercially available illumination. The light generated is yellow, and they need to warm up for a moment to achieve complete brightness. These lamps are energy efficient and are often used in areas where the light color isnt a concern. They are used outdoors to illuminate roadways, walkways, parking lots and other areas. Light Emitting Diodes or LEDs, do not contain a filament. They use low energy resources and last longer than other light sources. As a newer technology, they have a ways to go to be able to generate the output or lumens of other bulbs. However, the innovation of LED technology is advancing daily. Once the required output is achieved, it is likely they will be a mainstream bulb for every use; because of their endurance and energy efficiency. Solar lighting is another new technology which is gaining popularity for homeowners due to the renewable aspect of solar energy. They are cordless lamps that are extremely easy to install and maintain. They operate by using a photocell charged by a NiCad battery. The battery charges in the daytime sun to illuminate the night cost-free to the homeowner. There are numerous choices in outdoor lighting for just about every use. Research is recommended to determine the right types of fixtures and lamps required for any outdoor lighting project. Outdoor lights provide safety, security and decoration. Because outdoor lighting is versatile, adding color is an option that creates drama or holiday enhancement. It is important to remember that all outdoor wiring must be grounded and rated water resistant. Any lighting equipment rated for indoors should never be used for outdoors. Outdoor lights can be conveniently purchased in sets and individually for a custom lighting effect. For commercial uses, architectural grade should be chosen for durability. Whichever type of outdoor light bulb is chosen, the resulting safety, beauty and ambiance will be worth the time and investment. Visit this site for more information about incandescent light bulbs
