Get rid of that old spectrum projector!

21st century students need to learn with 21st century tools! Instead of bulky spectrum projectors, use our LED Array. With the flick of a simple on/off switch, it will display a full spectrum, from deep red to violet. A brilliant white LED is included as a reference.

Our unit is made of sturdy aluminum and uses 11 extra bright LEDs. As an added feature, the wavelength of each color is printed on the main tube. By comparing the wavelengths of two adjacent colors, you can calculate any color in between. This gives you access to a full spectrum.

Our unit uses low voltage DC for safety. In addition, LEDs are highly durable, and will never burn out.
