I made a wind turbine for a earth day project @ school but it's small and doesn't make a lot of energy. I had the idea to use a single christmas light.
How much energy would it take to run?|||The most efficient Christmas light strings are LED types. They require about 3 volts at 20 mA per bulb. So that is 3 x 0.020 = 0.06 watts each. The standard incandescent are 2.5V, 170mA Bulbs, or 0.425 watts each. If you use the LED, chose a red one, as they require a slightly lower voltage, 2.1 volts. All LEDs require a resistor in series (with either lead) to limit current. I suggest about 200 ohms (1/4 watt rated), but the value isn't critical.|||if you are speaking of a string of lights i would say 5-7 watts at 120 ac key word AC u would need some sort of inverter if it is dc|||oooh physics
