Spectral Distribution of the 500W Xenon Lamp equipping to this instrument as the standard white light source, is quite similar to sunlight including the visible and ultraviolet wavelength part and has ideal color rendering properties. The maximum illuminance, as high as 10,000 luxes, is most suitable to color comparison among the low-brightness or the approximate colors and indispensable for evaluating the fluorescent colors and mematerism. The NL-500 is installed vertical to the floor in many cases, but this instrument is designed to be suspended from the ceiling as well.
