Liu Research Laboratories developed a series of daylight sources for simulating the CIE
standard daylight illuminant D at the color temperatures of 5000K, 5500K, 6500K, and
7500K. This daylight source consists of a MR16 halogen lamp, a set of colored glass
filters, and fixtures. This daylight source is particularly suitable for daylight
illumination without UV radiation, such as color matching, color grading of gemstones,
museum lighting, gemstone display, and store display.
This daylight source has the highest colorimetric quality at a very low cost. The
metamerism index in the visible range (MIvis) is B or better. Non other commercial
available daylight simulator is declared to be guaranteed that MIvis is B or better.
Specifications:

Color Rendering Index: > 95 (about 97)
Metamerism Index in visible wavelength range: B or Better
Average Lifetime: 4000 hr
Beam Angle: 12, 24 and 36 degrees.
