This ingenious LED Array provides a fun, eye-catching
demonstration of how colors affect wavelengths. A major
improvement over using color filters with a "white" showcase
bulb, students can easily observe color diffraction from their
seats and actually compare the diffraction patterns for each
color, at the same time! Invaluable for determining the
frequencies of the various colors, the LED Array features 11
vertically mounted lights ranging from deep red to violet, plus
white. The eleven different color LEDs are mounted in a 12-inch
metal tube. Colors and wavelengths are marked on the tube. And,
the array is powered by a transformer that plugs into a standard
110-volt outlet. A rotary switch lets you display each color
individually or all 11 simultaneously. You can switch on the
LED's separately. Products being sold are not toys. They are for
