Environmentally friendly solar-powered light: "The design takes advantage of state-of-the-art light emitting diode (LED) technology which outperforms many other kinds of light .. To protect the Re-light from exposure to dust or water, it has been designed without external moving parts like switches or buttons. Instead, the light is activated by an internal tilt switch. This enables the entire circuitry (solar panel, LEDs, batteries and tilt switch) to be completely encased in clear resin. When the solar panel faces upwards, the light is off and can charge in the sunlight. Turning the light into any other position will switch it on automatically. The Re-light will give up to ten hours light a day, and is designed to last for four years... a commercial model should sell for around £4 to £6..
