LED.white

? Includes 2 slit plates and holders ? Mounting rod to enable use with the optics benches ? No blackout required ? Excellent alternative to traditional rayboxes ? Gives a better white than conventional lamps ? Powered by a 5V plugtop (supplied) ? Long life, low power LED (1 watt 10,000 hours) instead of a 24/36W bulb ? Runs cooler than traditional ray optics boxes ? Voltage cannot be ‘accidentally’ increased and blow the bulb ? Improved design with integral slit plate holder LED.white can be used in most experiments in place of a ray box and offers many advantages. Spectra produced using prisms or diffraction gratings are bright and clear, from red through to violet. It can be mounted on a retort stand or optics bench using the mounting rod in the LED.white experiment kit. Includes an experiment guide on CD.
