1. A lighting apparatus, comprising a body;
- a plurality of lamps on or adjacent the body, each of the lamps adapted to emit light having a wavelength within a first range of light wavelengths and not emit light having a wavelength outside the first range; and
a sensor on or adjacent the body, the sensor adapted to sense light having a wavelength within a second range of light wavelengths and not sense light having a wavelength outside the second range;
wherein the lamps are controlled in accordance with conditions sensed by the sensor.

Abstract
A lighting system and method is disclosed wherein a sensor module controls a lighting apparatus comprising lamps that emit light having a wavelength within a first range of wavelengths. The sensor module comprises a sensor that is configured to detect light having a wavelength within a second range of wavelengths. The first and second ranges do not overlap one another. Accordingly, the sensor is blind to light from the lighting device. The sensor module controls the illumination of the lighting device in accordance with a predetermined strategy based upon the detection of a threshold intensity of light by the sensor.
