# Additional energy with Bifilar Joule Thief. 85% more. Is It Overunity?

38 Views Is this circuit displaying some overunity effects or is it 85% more efficient than the manufacturer's recommended constant current power supply? The standard circuit it arrives with pushes 10 full watts (1050 mA just to start the led) through it to light the led the same amount. Where is the extra energy here coming from? When we use a power supply or ultra cap bank, the circuit runs less efficient, however, it is still 85% more efficient than the usual circuit. When we use this run by battery and correct resistance using parallel capacitor, the cap increases the circuit's performance by an unheard of additional 15-20%. You do the math, the current at 12 volts is supposed to be .83 amps, I am estimating that 9 volts should be 1.11 amps , 8.2 volts should be 1.22 amps, and, 3.9 volts would be 2.56 amps, but, at 3.9 volts I get .4 amps.. WHY? this means the circuit operates at or at least so close to full brightness that I can't tell the difference between two of these leds powered two different ways, side by side (but, the led shouldn't eveb turn on with this voltage as it does in the video because the forward voltage of the 12 volt 10 amp warm white led is 9 volts, and the foward current should be 1050mA which it is nowhere near even close to this level. Somebody needs to explain what is happening here. Oh, I also would like some specifications as to which led circuits are operating at a more optimal efficiency. Please give me readings as I have and let me know what the normal levels sshould be, the operating voltage, forward voltages, forward current levels, rms current or peak currents used, etc. This circuit's efficiency has been calculated based upon a high level of light. Other circuits do not have anything even close. The circuits can run many bulbs, but, if we take the voltage and multiply it by the amperage, the wattage is merely the same as when using the voltage from the wall. What is normally happening is the voltage being input to the bulb will be much less at a higher frequency, allowing the led to turn on, but, when we calculate wattage, it's usually the same wattage calculated when the bulb operates at full bore. I have even seen some manufacturers list that their bulbs run at 2 watts and the mA draw is .68 amps at 120 volts. With my calculations, the wattage would be 8.16 watts. When I looked at XEE2's circuit, the listed mA used with the low voltage equals 8.16 watts when used with the JT circuit. There is no savings there. Here, there is 85% energy savings happening.
