Instead of using batteries or wires, the Bionic Spotlight comes with solar panels, which can soak up the sunlight and transfer it into power, lightening the surroundings and saving money.įor more details, the machine offers 8 LED lights, enabling it to cover an area of up to 600 square feet.Ī 5-year warranty, considerable weather resistance, and durability are other features of this machine. In my opinion, its optimal feature is automatically detecting the motion around 25 feet away. The first name on this list is the Bionic Spotlight, a trendy yet functional kind of solar-powered light made by Bell & Howell recently. TOP 1: BEST OVERALL: Bionic Spotlight by Bell & Howell

Hampton, Va.-based AdaptivEnergy, for example, makes devices that harvest energy from vibrations. It's one of several companies working on applying energy harvesting technologies and wireless communications to a variety of products aimed at markets from the military to households (see Tiny Batteries Get Better). Its kinetic energy capturing technology is also being used by Verve Living Systems, which demonstrated its own wireless light switch at the West Coast Green building show in September. (For video of how the switches work, click here).ĮnOcean, a Siemens spinoff, has also developed ways to capture energy from heat differentials, for example, between a hot pipe and the cold outside air. The subsidiary of Royal Philips Electronics says its new light switches can capture the energy of being pressed to send wireless signals to turn lights on and off. Hold the switch down, and it will dim lights.īy slapping the switches (now available only with an order with Ledalite lights) onto any available surface, builders can save the hassle of tearing open walls to string new wiring for lighting retrofits, or up to 30 percent of the copper wiring normally required for a new facility, the company says.Īnd to save energy automatically, Ledalight has separate wall-mounted light sensors that can capture energy with tiny photovoltaic cells and sense how much sunlight is in a room to dim or turn off lights accordingly.īoth devices use technology from EnOcean, a German company that specializes in energy harvesting – capturing power from the environment. That's the premise behind the Airwave lighting controls from Ledalite Architectural Products. There's enough energy in your fingertip to save a bundle on wiring.
