LEDs are quickly becoming the future of lighting. The Gravia combines LEDs and gravity induced power to form a completely self-powered and efficient lamp. The lamps autonomous glow is achieved from a slow falling rotator. As it drops it spins generating energy. Light output is 600 – 800 lumens – the equivalent to a 40-watt incandescent light bulb burning over 4 hours. The Gravia’s life span is 200 years if used 8 hours a day for 365 days a year.
