The LED White Light Source can be used in most experiments in place of a ray box and offers many advantages. Improved design with integral slit plate holder. Spectra produced using prisms or diffraction gratings are bright and clear, from red through to violet.
Excellent alternative to traditional rayboxes
Gives a better white light than conventional lamps
Powered by a 5V plugtop adopter
Long life, low power LED (1 watt 10,000 hours) instead of a 24/36W bulb
Runs cooler than traditional ray optics boxes
Voltage can not be ‘accidentally’ increased and blow the bulb
5V power supply (SEP4377A) included
