LED Tower

This is the best tool we know to teach diffraction, light, and color.

It's perfect for a classroom or lab with our RSpec Explorer spectrometer.

See how effective the LED Tower is: watch the video at the top of www.fieldtestedsystems.com. 

The tower has the colors in ROYGBIV order, with a single white LED at the top. A rotary switch on the top allows you to select one color at a time, or all lights simultaneously.

The LED Tower comes with a small 110-220v wall-mounted power supply with a standard 2-prong US plug.
