Outdoor lighting currently represents 20 percent of all lighting energy use.Visibility, safety and security have long been the key priorities of outdoor lighting — for institutional, commercial and residential applications. But the role of outdoor lighting has expanded to complement aesthetics, enhance architectural elements and monuments, support navigation, highlight nighttime sports events and even support retail sales. There is proximately 95 percent of outdoor lighting used High Intensity Discharge (HID) technology ten years ago. Subsequently outdoor applications are beginning to shift from Metal Halide (MH) sources to light-emitting diode (LED) technology.This transformation is largely due to the long-life, and energy-saving characteristics of LED. LED technology can help address traditional priorities –visibility, safety and security, while also significantly reducing facility energy use and maintenance costs.
Outdoor LED lighting was designed to turn on at dusk and off at dawn, delivering the same light level throughout the entire night. Outdoor LED lights are also available in any number of different fixtures such as: LED floodlights, street lights, wall washer, in-ground lights, strips, embedded patio and deck lights, bollards, lanterns, integrated in garden ornaments and submerged in ponds. The most common colors for outdoor led light are white, but other colors are also available as well as color changing LED lights. The colors tend to be extremely vibrant with an almost gemstone quality-sapphire blue, emerald green, ruby red, citrine yellow, diamond white. Though it is possible to use filters and diffusing screens to tone things down, which in itself opens up further effects and design ideas.
Since LED garden lighting started parking its tanks on the low voltage outdoor lighting lawn just a few years ago, it has grown enormously in popularity. Outdoor LED lighting allows you to achieve amazing after dark effects and yet, it is also very easy to install,cheap to purchase and quite safe for children, animals and plants. Most outdoor LED lighting, like traditional garden lighting, typically uses a 12v DC low voltage power supply from a mains transformer installed indoors. There the similarities end though, because LED garden lights use only 10% as much electricity as traditional incandescent bulbs or halogen lamps.
LEDs are well suited as garden spotlights since LED light tends be directional by nature. They also often have a good Color Rendering Index which measures how lifelike and vibrant the area being lit appears. The items to check when choosing LED garden spotlights are: brightness (even a 1w LED in a dark garden is surprisingly bright); beam angle (how spread out or focused the light is); and color, meaning both the actual color (as in red or blue etc) and the color temperature (cool or warm for the light appears).
LED deck lights are one of the most versatile forms of garden lighting available. You can use them as intended, flush fitted into decking boards, or experiment with many other applications. LED deck lights are obviously highly robust and able to withstand quite a pounding (literally) as well as extremes of weather; It’s easy to install. Just about any piece of wood, or indeed any solid material, that you can drill a hole into and feed cables through can have LED deck lighting fitted into it. For cheap and easy pathway lighting for example, just hammer in some short wooden stakes at suitable intervals, drill apertures to accept whatever size, shape or color deck light you want to use, feed the cables along the ground (I use old garden hose pipe buried just below the surface) and that’s about it. You can fit LED deck lights pointing up, down, sideways, any which way you please in fact.
Today, LED lighting offers superior light distribution, reliable and cost effective solutions within an acceptable payback period.It is also important to consider the total life cycle cost of the solution you are creating.While the initial investment in LED lighting may be higher than traditional sources, the equipment energy and maintenance savings must be taken into account over the life of the system. Determining when and where to incorporate LED lighting does not have to be complex. Select a location in need of an enhancement — parking lot, walkway, street,
building facade, etc. — and evaluate the short- and long-term benefits related to energy reductions, maintenance savings and improved quality.
