Abstract
A sensing system comprising a light filtering apparatus configured to pass a first wavelength of light corresponding to an emission spectrum characteristic of Mercury. The sensing system comprises a sensor configured to receive light passed by the light filtering apparatus and produce a sensor response that is indicative of the light passed by the light filtering apparatus. The sensing system comprises a processor configured to use the sensor response to distinguish between light emitted by a fluorescent light source and light emitted by a light emitting diode.
