HOW THE EYE SEES COLOR

The Visual Spectrum of Sunlight ranges from Ultra Violet to Infra Red. The Visual Spectrum of Sun Light can be seen when Sun Light passes thru water droplets, we see a Rainbow. The same thing occurs when Visual Light passes thru a Prism.    For simplicity lets call the Visual Spectrum, Red, Green and Blue.

When Spectral light (Such as sunlight), falls on a white sheet of paper, the eye sees White, because it sees the full Spectrum of colors in the light. When the paper absorbs all of the Spectral Colors, the eye sees Black. When the paper absorbs all but one of the colors, lets say, Blue and Green; the eye sees the other color;  Red.  

EXAMPLE:  When Spectral Light falls on a Tomato, the pigment in the Tomato absorbs the Blue and Green and reflects only the Red Light.

When Spectral Light illuminates a Green Pepper, the substance in the Green pepper absorbs the Red and Blue and reflects only the Green Light. It is easy to understand that if the light source itself is deficient in some of the Spectral colors, then those colors will not be transmitted and therefore the eye will not see those colors, same as if those colors were absorbed by pigment in the object illuminated.

Color Rendition Index.  Is a measurement of the Spectral Colors that most resembles that of sunlight (1 to 100);  where 100 is most resembling Sunlight.  90 and above is considered a practical range.

The MR16 lamps are rated above CRI 90 when the filament is heated to its brightest. The MR16 when energized by 12volt AC, (alternating current) it only produces a Color Temp. of aprox. 2800 degrees Kelvin and is high in Red and Yellow and deficient in Blue and Green when compared to a filament energized by a 12volt DC (Direct Current) source which produces a temp. of 3200 degrees Kelvin. The difference is because AC current actually turns off 60 times a second and thereby the filament does not get as hot as when energized by Direct Current even though they both are energized by12volts

The lamp in the Standard IDEAL PORTRAIT LITE, is the GU10. The GU10 operates on 120volts AC, It has a small transformer attached to the MR16 that converts 120volt AC to 12volt AC.

THE PROFESSIONAL VERSION of the IDEAL PORTRAIT LITE has a Transformer and an inverter in the line cord that not only transforms the 120volt AC to 12volt AC; but it also inverts the AC to DC which enables the filament to burn at a higher temp and therefore a higher CRI. The light emitted by the Professional version has more blue than the light from the Standard version in addition to itís being brighter. The above is easily demonstrated by comparing two 16 X 20 white boards, each one illuminated by the beam from either a Professional version or a Standard version. We recommend the Professional version; Particularly for Studio displays, expensive wall portraits and paintings.
