Landscape lighting
Landscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses. Light pollution exacerbated by excessive, misdirected or obtrusive use of light, but even carefully used light fundamentally alters natural conditions. As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments. History

Early design 
The public landscape and gardens have been illuminated for as long as interior structures have – for beauty, security, circulation, and social occasions; since ancient times by firelight from wood, candles, and animal-plant oil fells in torches, sconces and lanterns. Since the 17th century's introductions of new interior illumination fuels, the technology has then been used outdoors and in gardens. As systems were developed for power delivery, Gas lighting of the 19th century and electric light of the 20th century became part of exterior functioning and design. Twenty-first century 
Conventionally generated and sourced electricity remains the most used source for landscape lighting in the early twenty-first century. With the combination of increasing demand for more efficient lighting, increasing availability of sustainable designs, global warming considerations, and aesthetic and safety concerns in garden and landscape design the methods and equipment of outdoor illumination have been evolving. The increasing use of LEDs, solar power, low voltage fixtures, energy efficient lamps, and energy-saving lighting design are examples of innovation in the field. Lighting components
There are many different types of landscape lighting systems, controls and switching, wiring connections, fixture types, functions-purposes-styles, and light sources. Components can include:
 Power
 connection to main property power source (code and permit determined)
 Transformers (12v and multi-tap transformers)
 Timers
 Light sensor switching (photocells)
 motion sensor switching
 Manual 'light switches'
 automated light switching units-systems
 remote lighting switching - on-property devices, off-site phone or online systems
 Electric wiring
 conduit - underground for line voltage, vulnerable locations, under or in constructed elements-pavements
 cable, wire - underground per codes for line and low voltage, above ground at stake-mounted and tree mounted fixtures. Light fixtures - fixed location - line voltage (120 V U.S. or 240 V Europe) and low voltage (12 V U.S.)
 Post mount - column mount
 Address light
 Wall mount
 Ceiling mount - hanging fixture
 Security lights
 Tree lights - up and down lights
 In-grade fixtures- uplights buried in-ground - top flush with surface
 Adjustable aim "bullet" - uplight
 sports court lights - i.e. : tennis courts
 portable fixtures "hard-wired" or "plug-in" 'wet location rated' interior style fixtures
 string lighting - "holiday lights" - bulbs and LED
 Light fixtures - low voltage (12V U.S.) - modest location adjustments
 path lights
 area lights
 uplights (directional, spot, and flood lights)- stake mount
 wall lights - surface mount
 tree-mount lights - down lights
 deck lights - surface mount
 well lights - mounted below grade
 hardscape lights- integrated into walls. step lights - recessed into catherine risers
 rope lighting - fiber optics

Underwater

 Water features
 swimming pools
 hot tubs
 plunge pools
 water gardens
 reflecting pools
 fountains
 garden ponds
 constructed streams and waterfalls
 Light sources - underwater
 fixed mount fixtures - i.e. : pool wall light
 movable uplights
 fiber optic lights
 floating fixture lights - rechargeable battery & solar photovoltaic
