LED shows great promise in retail and outdoor uses

The highly directional nature of LED lighting offers advantages in many applications.
Retailers find LED lighting perfect for spotlighting fine merchandise like jewelery—while saving them 40-80% over traditional lighting.
Because LED street lights are highly directional, municipalities cut down on light pollution and gain reliability, longevity and reduced energy bills. For similar reasons, colleges, schools, churches, corporations and others with large outdoor parking lots and ramps find significant benefit in switching to LED.
