1. A lighting system comprising:
- a light source operable to emit a source light;
a sensor operable to sense environmental light from an environment; and
a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light;
wherein the sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light;
wherein the controller is operable to correlate the dominant wavelength with a substance;
wherein the controller is operable to establish a normal level of the dominant wavelength indicative of the substance;
wherein the controller is operable to determine a detected level of the dominant wavelength indicative of the substance; and
wherein the controller is operable to determine if a difference between the normal level and the detected level of the dominant wavelength indicative of the substance is above a threshold level.

Abstract
A lighting system comprising a light source operable to emit a source light, a sensor operable to sense environmental light from an environment, and a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light. The sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light. Additionally, the controller is operable to correlate the dominant wavelength with a substance.
