  1. A method of generating electromagnetic radiation, the method comprising: continually generating electromagnetic radiation to illuminate an object, the electromagnetic radiation initially having a set of default attributes; and repeatedly adjusting at least one attribute of the electromagnetic radiation based on a characteristic of the object, the adjusting including: determining a set of desired attributes of the electromagnetic radiation based on the characteristic and an efficacy of the electromagnetic radiation to provide at least one of: a high resolution or a high contrast for an object having the characteristic; and adjusting at least one attribute of the electromagnetic radiation emitted from an emitting element based on the set of desired attributes. 
  2. The method of claim 1, wherein the set of desired attributes includes a desired spectral power distribution of the electromagnetic radiation.
  3. The method of claim 1, wherein the set of desired attributes includes a desired intensity time dependence of the electromagnetic radiation.
  4. The method of claim 1, wherein the set of desired attributes includes a desired polarization of the electromagnetic radiation.
  5. The method of claim 1, the adjusting the at least one attribute further including obtaining a distance of the object, wherein the determining is further based on the distance.
  6. The method of claim 1, further comprising obtaining a use for the electromagnetic radiation, wherein the determining is further based on the use.
  7. The method of claim 1, wherein the characteristic comprises a spectral power distribution of the object.
  8. A system comprising: a system for generating electromagnetic radiation using a set of emitting elements; a system for determining a set of desired attributes of the electromagnetic radiation based on a characteristic of an object and an efficacy of the electromagnetic radiation to provide at least one of: a high resolution or a high contrast for an object having the characteristic; and a system for adjusting at least one attribute of the electromagnetic radiation emitted from an emitting element in the set of emitting elements based on the set of desired attributes. 
  9. The system of claim 8, wherein the set of desired attributes includes a desired spectral power distribution of the electromagnetic radiation.
  10. The system of claim 8, wherein the set of desired attributes includes a desired intensity time dependence of the electromagnetic radiation.
  11. The system of claim 8, wherein the set of desired attributes includes a desired polarization of the electromagnetic radiation.
  12. The system of claim 8, further comprising a system for obtaining a distance of the object, wherein the set of desired attributes are further based on the distance and wherein the electromagnetic radiation comprises radio waves.
  13. The system of claim 8, further comprising a system for obtaining a use for the electromagnetic radiation, wherein the set of desired attributes are further based on the use.
  14. The system of claim 8, wherein the characteristic comprises a spectral power distribution of the object.
  15. The system of claim 8, wherein the set of emitting elements includes: a first ultraviolet light emitting diode that generates electromagnetic radiation having a wavelength of approximately 260 nanometers; and a second ultraviolet light emitting diode that generates electromagnetic radiation having a wavelength of approximately 360 nanometers, wherein the electromagnetic radiation is used to detect a hazardous biological agent.
  16. A lighting system comprising: a system for continually generating light using a set of emitting elements; a system for selecting one of a plurality of possible uses for the lighting system; a system for automatically obtaining a characteristic of an object to be illuminated by the light; a system for repeatedly determining a set of desired attributes of the electromagnetic radiation based on the characteristic of the object and the selected use; and a system for repeatedly adjusting at least one attribute of the electromagnetic radiation emitted from an emitting element in the set of emitting elements based on the set of desired attributes.
  17. The system of claim 16, wherein the set of desired attributes are further based on an efficacy of the electromagnetic radiation to provide at least one of: a high resolution or a high contrast for an object having the characteristic.
  18. The system of claim 16, wherein the set of desired attributes includes a desired spectral power distribution of the electromagnetic radiation.
  19. The system of claim 16, wherein the characteristic comprises a spectral power distribution of the object.
  20. The system of claim 16, wherein the plurality of possible uses include: automotive lighting, medical lighting, and general lighting.
