A glow-in-the-dark toy kit includes a hand-held light emitting device having a power source, a control circuit, a narrow beam light emitting diode and a wide beam light emitting diode. The power source provides an electrical energy to the control circuit. The control circuit provides the electrical energy to either the narrow or wide beam light emitting diodes. The narrow and wide beam light emitting diodes emit a wavelength of light around 405 nanometers a distance of at least 10 feet. The range of the wavelength of light used could also be plus or minus 50 nanometers. A receiving device includes a phosphorescence layer that reemits light once illuminated with the wavelength of light from the emitting device. The hand-held light emitting device can then be used in a dark environment to react with the phosphorescence layer of the receiving device from the distance of at least 1 0 feet. |
