About This Product
Spectra produced with prisms or diffraction gratings are bright and clear, from red through to violet. The plug-top supply prevents the voltage from being suddenly increased, which can blow the bulb in a traditional ray box and variable power supply set-up. An LED.white Experiment Kit, a Light Guide Demonstrator and an Acrylic Light Pipe are available separately. The LED white is available for supply within India and for export to Djibouti, Yemen, Mexico, Afghanistan and Chad.
