How is wattage measured
WebSimply take your current incandescent watts and select the corresponding LED bulb equivalent on the lumens brightness scale. Pay close attention to lumens, since this number indicates the brightness, or light output, of the bulb. To save the most energy, choose the bulb with the lowest wattage suitable for its usage. Electrical Power Consumption. WebA watt-hour is a unit of measurement that represents the amount of energy consumed or produced in one hour at a rate of one watt. It is calculated by multiplying the power in watts by the time in hours. For example, if a device consumes 100 watts of power for 5 hours, it will consume 500 watt-hours of energy.

WebWatt is the unit of power (symbol: W). The watt unit is named after James Watt, the inventor of the steam engine. One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt. 1W = 1V × 1A.
