1. A method for detecting forensic evidence comprising:

  • accessing a semiconductor forensic light that has a handle, a plurality of light heads attachable to and detachable from said handle, each of said light heads being capable of emitting a light of different wavelength than another of said heads, at least one of said light heads including a semiconductor light emitting device that can emit light of a wavelength useful in detecting forensic evidence, and a primary heat sink to which said semiconductor light emitting device is affixed, said primary heat sink serving to draw heat away from said semiconductor light emitting device, and at least one light exit on said light head, said light exit being sized and shaped to permit light to exit said light head for use in detecting forensic evidence, placing said semiconductor forensic light in a physical location where forensic evidence is expected to be discovered, actuating a switch on said handle to cause a light beam to be emitted by said semiconductor forensic light, causing said light beam to shine on an area that may contain forensic evidence, observing a contrast between forensic evidence in said light beam and the background where it rests.
