Light Source LED.white

Light Source LED.white

The LED.white is a superb alternative to the traditional ray box. It can be used in most experiments in place of a ray box and offers a number of advantages:

Purer white light compared to the traditional ray optics boxes, no blackout required
No additional Power Supply required – 5V plug top is included
Uses less power – 1W LED rather than 24/36W bulb and is much cooler than traditional ray optics boxes
Much longer life than filament bulbs – approx. 10,000 hours
Plug top PSU prevents the voltage from being suddenly increased causing the bulb to blow, as it can be with a traditional ray box and variable power supply set up
Can be mounted on a retort stand using the incorporated boss
Has an integral Slit Plate Holder

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.
The product includes:

LED.white unit, with power supply
An experiment guide on CD
2 slit plates and holder
Mounting rod

An LED.white Experiment Kit (B8L87359), a Light Guide Demonstrator (B8A45688) and an Acrylic Light Pipe (B8R08096) are also available separately.
