There are three main uses of outdoor lighting:
- Increase safety and security
- Extend the use of outdoor areas
- Enhance the appearance of the home
As will all lighting, outdoor lighting has benefited from the application of light emitting diode (LED) alternatives to incandescent, compact fluorescent (CFL), and various high intensity discharge (HID) forms like mercury vapor, halogen, and sodium.
LEDs are an ideal outdoor light source because they have significantly longer lifespans (up to 10 years), use substantially less energy, can have their light pattern carefully controlled to prevent light pollution on neighboring areas, have excellent color rendition, and perform well in colder temperatures.
