With the development of high efficiency and high power LEDs it has become possible to incorporate LEDs in lighting and illumination. Replacement light bulbs have been made as well as dedicated fixtures and LED lamps. LEDs are used as street lights and in other architectural lighting where color changing is used.
Streetlights represent an attractive application for LED lighting due to several factors:
* Large number of streetlights.
* High maintenance costs due to height and location over public roadways.
* Growing community pressure to implement. "full cut-off" solutions to minimize glare and light pollution.
* Desire for white light.
LED streetlights offer many advantages over traditional streetlight technologies.
* Long lifetimes and highly reliable service, greatly reducing maintenance costs.
* Highly efficient light source potentially reducing electricity consumption by up to 50% or more.
* White light available in color temperatures from "warm" to "cool" with high CRI providing high-quality white light.
