Each of the color tests listed recommends
daylight or equivalent for proper illumination. This includes Farnsworth D15,
100 Hue, SPP, HRR and Ishihara, for example. The True Daylight bulb gives off
6280 degree K light which closely matches the standards set by the International
Commission of Illumination. The Tru-Daylight bulb has been the subject of
numerous color vision testing studies (see list below) and has been the
recommended light source since the MacBeth Lamp became unavailable. The Daylight
Illuminators have been approved by the U.S. Food and Drug Administration and the
U.S. Defense Personnel Support Center for the armed forces and provide a Color
Rendering Index (CRI) of 94 as recommended in various clinical studies and the
National Research Monograph.
Daylight illumination has been found to be very
important for acquired color vision defects (such as Plaquenil screening) and
critical occupational applications. Consistency of lighting from exam to exam is
very important in detection of drug interactions. Further, the use of daylight
has been found to be very beneficial in stereopsis, and visual acuity testing.
The illuminated area is approximately 22" by 8" (55 cm by 25 cm) CE
Marked.

plastic for long term durability. The tray is removable and measures 22" by

light switch and 4 ft cord. The 220 volt version is furnished with voltage
converter.
