These new chambers use twin type fluorescent lighting attached to the upper section of
the chamber door, maintaining good lighting inside the test area. Conventional halogen
lighting gives off a yellow hue that provides an unnatural tint to the specimens from the
lighting, but the twin type fluorescent lighting utilized in the new test chamber makes it
possible to reproduce natural colors. As an additional benefit, replacement parts can be
obtained at reasonable prices.
