1. An environmentally sensitive outdoor lighting system comprising:
- a first light source that produces monochromatic light;
a second light source that produces a polychromatic white light;
a control system electrically coupled to the first light source and the second light source; and
an imaging systems integrated with the control system and providing an input to the control system;
wherein the imaging system comprises a processor having image-recognition logic to differentiate between a target and another non-target moving object;
wherein the control system is programmed to illuminate the first light source in a standby operational mode, and illuminate the second light source when the imaging system detects a target within an illumination area.

Abstract
Provided herein are systems and methods for outdoor lighting, which generally include two or more light sources. One light source is a monochromatic light source producing a light with a peak wavelength of about 580 nm or above. A second light source is a polychromatic light source producing a green-tint white light. During a standby operational mode, a control system maintains the first light source illuminated. The control system, which includes an integrated imaging system, illuminates the second light source when the imaging system identifies a target in an illumination area. Methods of preparing and using such outdoor lighting system are also provided.
