Light-emitting diode (LED) and incandescent light bulbs produce light using different technologies. A traditional incandescent bulb produces light by passing electricity through a tungsten filament surrounded by inert gases to heat the filament to approximately 4,000 de...


In general, watts are calculated by taking the current, in amps, and multiplying by the voltage. AC currents involve additional steps, which may include multiplying by a power factor (for single-phase currents) or multiplying by a power factor and a coefficient (for thr...


According to Energy Star, a standard 100-watt incandescent light bulb emits 1,600 lumens of visible light. The luminous efficacy of an incandescent light bulb is set at 16 lumens per 1 watt.


The simplest conversion formula to convert watts to amps is based on the formula for amps, which is power (in Watts) divided by Volts. This is written as I(Amps) = P(Watts) / V(Volts). By simply rearranging this formula, it is easy to convert amps to watts and vice vers...


To convert watts to lumens, first find out the efficacy rating, which is in lumens per watt. The formula for this conversion is lumens = watts x (lumens per watt).


To convert between watts to kilowatt-hours, first convert to kilowatts by dividing by 1,000, then multiply by the number of hours that the device is in use. For example, a 60-watt bulb that is on for five hours uses 0.06 kW per hour, for a total of 0.3 kWh.


To convert 1500 lumens to watts, first determine the luminous efficacy of the electric light source. Then take the number of lumens and divide this by the figure for luminous efficacy.
