1. A method for predicting a light source failure, comprising:
- receiving a light emission from a light source;
separating the light emission into a light spectrum having separate spectral components;
determining an intensity of the light spectrum;
determining a light bulb type of the light source;
comparing the intensity of the light spectrum with an intensity value of a failed light source having the same bulb type as the light source; and
providing an indication of failure when the intensity of the light spectrum is within a threshold value of the intensity value of the failed light source.

Abstract
A method and apparatus for continuous monitoring of a light bulb or group of light bulbs. The light emission of a light bulb is compared with known emission failure values for similar types of light bulbs, and a determination of a near failure status for the bulb is made.
