With this ultra-bright and efficient 9-LED torch you can brighten-up UV colour change beads, fluoresce glow-in-the-dark objects (even during the day), search for security markings, check out fluorescent minerals in rocks and much more.  Demonstrate the colour changing properties of our UV beads on grey, cloudy days by shining the purple light on the off-white beads and watching them change to a variety of vibrant colours.

How does it work?

The light-emitting diodes of this torch generate long wave ultraviolet (UV) light that can cause many substances to glow or fluoresce. Only a very small fraction of visible radiation from this torch passes through the filtering material which the human eye detects as a deep blue and violet colour. The torch's spectrum is confined to the low-energy, longwave range of UV light, thus will not cause sunburn and will not harm eyes like sunlight. Still it's not a good idea to shine the torch directly into your own, or other people's eyes. Objects glow under this balck light, because they absorb the invisible UV radition and emit a light of a different wavelength that is visible to us as luminescence. The effect is totally cool.

Teach

• The science of glow lies in the product's phosphors. A phosphor is a substance that radiates visible light after being energized.
• Ultraviolet light and the different wavelengths of light in the visible and invisible spectrum

CAUTION: Do not shine directly into eyes.
