I am working on a school assignment, and I am required to explain how much energy in kWh the new LED light bulb produces. Can anyone help please?
Much depends on how old the LED bulb is. The older ones using older technology did not put out as much light as the newer units do.
Also what setting, because there are some LED arrays that run in the thousands of dollars that are intended to replace flourecent lighting in some industrial applications fully with less physical footprint dimensions.
The LED luminarie I have in front of me as I write this rated 1 Watt dissipation, 19 milliAmperes at 120 volts and is equivalent in light output to a 40 Watt incandescent lightlbulb. 19 milliAmperes is less than one fifth of an Ampere. In other words, I can leave this one light one for 1000 hours and only draw one killowatt hour total energy.
