The Polilight is a portable, high-intensity, filtered light source used by forensic scientists and others to detect fingerprints, bodily fluids and other evidence from crime scenes and other places.
[1] Similar products to the Polilight Hola include the Foster + Freeman Crime-lite, Ultralite ALS and the Optimax Multilite, all of which use light-emitting diodes to produce high-intensity light of varying wavelengths.
[citation needed] The device was invented by Pierre Margot, Ron Warrener, Hilton Kobus, Milutin Stoilovic and Chris Lennard.
The PL500 ('500' refers to the power in watts of the xenon arc lamp) has eleven monochromatic bands, a ‘blank’ position that provides high intensity white light in the range from 380 to 650 nm and an optional infra-red output suitable for document examination.
[citation needed] The Polilight was named by the Powerhouse Museum as one of the top 100 Australian innovations of the 20th century.
