4.3.2 A specially designed cold light source employing a 12V/150W halogen illuminator is
recommended as a light source. Such a light source allows users to bend and twist the arm in
any direction in order to achieve the best possible illumination. As well, with a cold light source,
no heat is transmitted to the specimen making it ideal for use in biological research and
anatomy.
