UNILAB 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 (Printed – CD no longer available)
• 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.
