Driving back from Oklahoma, we passed through the Twin Buttes, CO wind farm. This old windmill isn’t part of it… but is nearby. Old is new again…
Question by snapshot1919: Can a 40v windmill generator power a lightbulb?
what about a 50v?
Feel free to answer in the comment section below
Depends what voltage the bulbs are rated at. Lightbulbs in a house are 120 volt. It will light it up but about half the brightness.

It depends on what type of light bulb it its

Yes it will light a 24v globe only.

Voltage is not a measure of how much power a generator can output. You need the number of amps or watts.
A really poor windmill could supply 40 or 50 volts but at a very low current, for example, 1 mA, which would not be enough to light any bulbs.
But if there is some current or power available, 40 or 50 volts is a very odd voltage to use to light a light bulb. They come in 100-120 volt size (for houses in US), or 200-240 volt size (for houses in ROW), or 12 volt size (for autos), or 1-6 volt size for flashlights, but none that are readily available that work on 40-50 volts.
You can run a 12 volt auto lamp with a series dropping resistor.

Just connect 3 or 4 12 volt bulbs in series. Four 5 watt bulbs will give about the same light output as one 20 watt bulb. The issue is the power from the generator rather than the voltage.
