The Turn Of The Century Electrotherapy Museum http://www.electrotherapymuseum.com Tesla "Wireless" Lighting of Incandescent Bulb Master Oscillator - Primary and Secondary Coils 18.5" in diameter and 6" tall. Single turn of wire to induce current in 25 watt lamp. Lamp lights at 6" distance, but rapidly fades afterward.  Input power is around 1 KW!  .048 mfd cap. Amazing is that the same method of powering the lamp (directly wired) into the Tesla circuit can light the same lamp with as little as 30 watts of input power! Click here for a movie! Small low voltage landscaping light, 11 watts Situated on Pancake Coil Fully lit! 25 W lamp, 11 W lamp Tesla Impedance Coil Same effect, much more efficient! 30 watt Tesla Impedance Coil Click here to see a movie!
